Anchovies
Small, shimmering fish that travel in large schools, anchovies are vital players in Crete's marine food chain and a beautiful sight in clear waters. These silvery fish can form schools of thousands, creating mesmerizing underwater displays.
Open water, coastal areas
May - October
The European anchovy is abundant in Cretan waters, particularly around the north coast near Almyrida and Souda Bay. They form the backbone of the local fishing industry and have been a staple of Cretan cuisine for millennia. Ancient Minoans harvested anchovies, and today they remain a beloved ingredient in traditional Greek dishes.
Anchovies are schooling fish that move in tight, synchronized formations as a defense against predators. They feed on plankton near the surface, often attracting larger predators like tuna and barracuda.
Look for shimmering walls of silver near the surface during morning dives. Schools often congregate near rocky outcrops where currents bring plankton. Stay calm and let them surround you for an unforgettable experience.
Octopus
Masters of disguise with incredible color-changing abilities, octopuses are curious and intelligent, often hiding in rocky crevices or gliding along the seabed. They possess remarkable problem-solving abilities and can recognize individual humans.
Rocky reefs, caves, sandy bottoms
Year-round
The common octopus thrives in Crete's rocky coastline, especially around the dive sites near Almyrida. Cretan fishermen have traditional methods of catching octopus that date back centuries. In Greek mythology, the octopus was associated with the sea god Poseidon, and octopus remains a cherished delicacy in Cretan tavernas.
Highly intelligent and curious, octopuses actively hunt crabs, mollusks, and small fish. They can change color and texture in milliseconds to camouflage or communicate. Each arm contains a cluster of neurons, essentially giving them eight 'mini-brains'.
Search rocky crevices and look for telltale signs: shells and debris piled outside den entrances. Early morning or dusk dives offer the best sightings as they're more active during low light. Move slowly – they're shy but curious if you're patient.
Lionfish
Bright and striking but invasive, lionfish thrive in Crete's warm waters, reminding us of the delicate balance of marine ecosystems. Their venomous spines and voracious appetite make them formidable predators with few natural enemies in the Mediterranean.
Rocky reefs, wrecks, caves
Lionfish arrived in the Mediterranean through the Suez Canal (a process called Lessepsian migration) and were first spotted in Cretan waters around 2015. Greek marine biologists actively monitor their spread. While beautiful, they pose a threat to native fish populations.
Lionfish are ambush predators that corner prey using their fan-like pectoral fins. They hunt at dawn and dusk, consuming up to 30 times their stomach volume. In their native Indo-Pacific, sharks and groupers control their numbers, but Mediterranean species haven't learned to prey on them.
You'll definitely find them on the Minnewaska wreck and our Koutalas dive site, often hiding under overhangs and in crevices. Never touch them as their spines deliver a painful, venomous sting. Beautiful to photograph but maintain a safe distance.
Trumpetfish
Long and slender, trumpetfish mimic their surroundings perfectly, quietly hunting while adding elegance to shallow coastal waters. They can change color to match corals, seagrass, or even shadow larger fish.
Rocky reefs, seagrass beds
June - October
Another Lessepsian migrant, the Atlantic trumpetfish has established populations along Crete's south and north coasts. They're regularly spotted at Almyrida's rocky reefs. Their arrival reflects the Mediterranean's ongoing transformation as waters warm.
Masters of stealth hunting, trumpetfish often position themselves vertically among sea fans or grasses, swaying with the current. They sometimes 'shadow' larger fish like groupers to get close to prey, then strike with lightning speed using their tubular snout.
Look for them hovering vertically near rocky walls or hiding among posidonia seagrass. Their camouflage is excellent, so scan slowly. They're not shy and can be approached closely for photography – just avoid sudden movements.
Stingrays
Smooth and graceful, stingrays glide over sandy seabeds, playing a key role in balancing the marine ecosystem with their gentle presence. Their flattened bodies and elegant movements make them one of the most mesmerizing sights underwater.
Sandy bottoms, seagrass meadows
May - September
The common stingray is native to Cretan waters and frequents the sandy areas between Almyrida and Georgioupoli. Local fishermen have respected these creatures for generations, and they feature in ancient Cretan art. The warm, shallow bays of northern Crete provide ideal habitat for juveniles.
Stingrays spend much of their time partially buried in sand, ambushing crustaceans and mollusks. They detect prey using electroreceptors that sense the electrical fields of hidden animals. Despite their venomous tail spine, they're docile and only sting in self-defense.
Scan sandy bottoms carefully – they're masters of burial. Early morning dives often reveal them actively feeding. Approach from their front where they can see you, and never corner or touch them. The sandy areas near Ombros Gialos are prime stingray territory.
Squid
Agile and fast, squid dart through Crete's waters with remarkable camouflage skills, playing a vital role as hunters in the marine environment. Their intelligence and communication abilities rival those of their octopus cousins.
March - June, September - November
European squid are commercially important in Crete, with Chania's harbor hosting a traditional squid fishing fleet. Night fishing for squid using lights is a beloved local tradition. In spring, large aggregations gather in Cretan bays to mate, offering spectacular diving opportunities.
Squid are active predators that hunt in groups, communicating through rapid color changes. They can propel themselves at speeds up to 40 km/h using jet propulsion. Their large eyes provide excellent vision, and they're remarkably intelligent for invertebrates.
Night dives dramatically increase squid sightings as they're attracted to lights. Look for them in open water above sandy bottoms. During mating season, they're less skittish and allow closer approach. Their chromatophore displays are spectacular under torchlight.
Moray Eels
These serpentine creatures are often seen peeking out from rocky hideouts, their striking patterns and impressive teeth making them memorable encounters. Despite their fearsome appearance, they're generally shy and reclusive.
Rocky reefs, crevices
The Mediterranean moray eel is abundant around Crete's rocky coastline, particularly near Almyrida and Koutalas dive site. Ancient Greeks believed moray eels were sacred to Apollo, and wealthy Romans kept them in elaborate pools. Today, they're a highlight of Cretan diving.
Morays breathe by constantly opening and closing their mouths – not a threat display. They're nocturnal hunters with an excellent sense of smell, preying on fish and octopuses. Many form symbiotic relationships with cleaner shrimp that remove parasites.
Check rocky crevices – morays often share space with lobsters. They're curious and will sometimes emerge to investigate calm divers. Never hand-feed them (a common but dangerous practice).
Grouper
Large and curious, groupers are often the highlight of dives, approaching divers with interest and commanding presence. These intelligent fish can live over 50 years and grow to impressive sizes.
The dusky grouper was once severely overfished in Greek waters but is recovering thanks to marine protection efforts. Around Crete, established dive sites where groupers are protected have resident individuals that divers can visit repeatedly. Some dive operators name their regular grouper companions!
Groupers are territorial and often return to the same cave or wreck for years. They're protogynous hermaphrodites – all start as females and larger individuals become males. Remarkably intelligent, they can recognize individual divers and even cooperate with moray eels when hunting.
Groupers respond well to calm, slow divers. Avoid swimming directly at them; approach at an angle. Regular dive sites have habituated groupers that are very approachable. The SS Minnewaska wreck is home to several large resident groupers.
Sea Bream
Silvery and abundant, sea bream are commonly spotted in schools around rocky reefs, adding movement and life to every dive. Several species inhabit Cretan waters, each with distinctive markings.
Rocky reefs, seagrass, sandy areas
Various sea bream species including the two-banded bream (Diplodus vulgaris) and white bream are staples of Cretan marine life. They've been depicted in ancient Minoan frescoes, proving humans have admired them for over 3,500 years. Today they remain central to Greek fishing and cuisine.
Sea bream are diurnal and feed on algae, small invertebrates, and sea urchins. They often form mixed schools with other species. Their strong teeth can crack sea urchin shells with ease, making them important for reef health.
You'll encounter sea bream on virtually every dive in Crete. They're most active in morning hours. Schools often gather near cleaning stations where small wrasse remove parasites. Great subjects for underwater photography practice due to their abundance.
Nudibranchs
These colorful sea slugs are tiny treasures for observant divers, displaying an incredible variety of patterns and hues. Over 3,000 species exist worldwide, with dozens found in the Mediterranean.
Rocky reefs, algae, sponges
March - June
Crete hosts numerous nudibranch species including the striking flabellina, the purple dorid, and the solar-powered Elysia. The nutrient-rich waters around Almyrida support diverse nudibranch populations. Spring is prime season when they emerge to mate and lay distinctive spiral egg ribbons.
Nudibranchs are specialized predators – each species typically feeds on one type of prey like sponges, hydroids, or anemones. Some incorporate their prey's stinging cells for defense. Many species are hermaphrodites and perform elaborate mating rituals.
The most common place to find nudibranchs is on the Minnewaska wreck, where they thrive on the encrusted surfaces. Slow down and look closely at rocks, sponges, and algae. Photography requires macro lenses and patience. Early morning and overcast days often yield more sightings.
Seahorses
Rare and enchanting, seahorses cling to seagrass and algae, offering patient divers a magical underwater encounter. These unique fish are monogamous and famous for their unusual reproduction.
Seagrass meadows, algae beds
The short-snouted seahorse inhabits Crete's posidonia seagrass meadows, though populations have declined due to habitat loss. Conservation efforts are underway across Greece to protect these beloved creatures. Sightings near Almyrida are treasured moments that divers remember for years.
Seahorses are poor swimmers who anchor themselves with prehensile tails. Males carry fertilized eggs in a brood pouch and give 'birth' to hundreds of tiny fry. Pairs perform daily greeting dances, changing colors and swimming side by side.
Search seagrass beds very carefully – seahorses camouflage brilliantly. Never touch or hold them as stress can be fatal. If you're lucky enough to find one, maintain distance and limit photography time. Alert your guide so others can see, but never crowd the animal.
Mediterranean Barracuda
Sleek and fast, these impressive predators patrol the waters around Crete, their silver bodies flashing in the sunlight. While smaller than their tropical cousins, they're no less impressive.
Open water, rocky reefs
The European barracuda is native to Cretan waters and is commonly seen at most dive sites around Almyrida. Unlike tropical barracuda, they're not considered dangerous to humans. Schools of juvenile barracuda are a common sight during summer months in shallow bays.
Barracuda are ambush predators that rely on speed and sharp teeth. They often hunt at dawn and dusk, using bursts of speed up to 45 km/h. Large individuals are usually solitary, while juveniles form protective schools.
Look for them in open water near drop-offs and reef edges. They're attracted to shiny objects, so remove jewelry before diving. Schools of juveniles make excellent photo subjects. Larger individuals often hover motionless, allowing close observation.
Cuttlefish
Often called the 'chameleons of the sea,' cuttlefish are masters of camouflage with remarkable intelligence. Their ability to change color, pattern, and texture in an instant makes every encounter mesmerizing.
Sandy bottoms, seagrass meadows, rocky reefs
The common cuttlefish is abundant in Cretan waters, particularly in the sandy bays and seagrass meadows around Almyrida. Spring is mating season when cuttlefish gather in shallow waters, making them easier to spot. Local fishermen have targeted cuttlefish for centuries, and they remain a prized ingredient in traditional Cretan cuisine.
Cuttlefish have the most sophisticated color-changing ability in the animal kingdom, controlled by millions of chromatophores in their skin. They hunt by mesmerizing prey with pulsating color displays before striking with lightning-fast tentacles. Males perform elaborate courtship displays, and they're known to be highly curious about divers.
Search sandy areas adjacent to seagrass beds and rocky outcrops. They're often found hovering just above the bottom or partially buried in sand. Approach slowly – they're curious and may display for you. Spring mating aggregations near Koutalas offer spectacular encounters. Night dives can reveal their incredible bioluminescence.
Mediterranean Monk Seal
One of the world's most endangered marine mammals, the Mediterranean monk seal is a rare and precious sight in Cretan waters. These gentle giants have called these coasts home since ancient times.
Sea caves, rocky coastlines, remote beaches
March - May
Crete is one of the last strongholds for the Mediterranean monk seal, with an estimated population of fewer than 700 individuals remaining worldwide. The remote southern coast of Crete, with its numerous sea caves, provides critical habitat for breeding and resting. Greek conservation organizations actively protect these animals, and Crete's caves have been used by monk seals for millennia.
Monk seals are shy and elusive, preferring remote caves and beaches away from human activity. Females give birth in sea caves, nursing their pups for several months. They feed on fish, octopus, and crustaceans, diving up to 200 meters deep. Despite their size, they're gentle and non-aggressive toward humans.
Monk seal encounters while diving are extremely rare and should be treasured. If you're lucky enough to spot one, maintain a respectful distance of at least 10 meters and avoid following or cornering the animal. You might just catch a glimpse of them tucked inside the mysterious Elephant Cave.
Sea Turtle
Ancient mariners of the Mediterranean, sea turtles are gentle giants that have navigated these waters for millions of years. Encountering one underwater is a truly magical experience that stays with divers forever.
Open water, seagrass meadows, rocky reefs
The loggerhead sea turtle (Caretta caretta) is the most common species in Cretan waters. Crete's south coast, particularly around Rethymno and Chania, hosts important nesting beaches. The warm waters around Almyrida serve as foraging grounds where turtles feed on jellyfish, crabs, and mollusks.
Sea turtles are air-breathing reptiles that can hold their breath for up to 7 hours while resting. They migrate vast distances between feeding and nesting grounds. Females return to the same beaches where they hatched to lay their own eggs. They're generally calm around divers and may approach out of curiosity.
Keep a respectful distance of at least 3 meters – they're protected by law. Never chase or touch them. Early morning dives increase chances of encounters as they're often resting on the bottom. Look for them near seagrass beds where they feed. If one approaches you, stay still and enjoy the moment.
2025 became a landmark year for Almyrida, as tiny sea turtles emerged from their nests for the very first time and made their journey across the beach to the sea, marking the beginning of an exciting new chapter for the coastline.
Upside Down Jellyfish
These unusual jellyfish spend most of their time pulsing gently on sandy seabeds with their bell facing downward. Their distinctive behavior makes them one of the most fascinating creatures to observe in shallow Cretan waters.
Shallow sandy bays, seagrass margins, warm lagoons
The upside down jellyfish is a Lessepsian migrant that entered the Mediterranean through the Suez Canal. First spotted in Cretan waters in recent years, they've established populations in warm, shallow bays along the north coast. Their presence reflects the ongoing warming of Mediterranean waters and the changing marine ecosystem.
Unlike typical jellyfish, Cassiopea rest upside down on the seabed, pulsing gently to circulate water over their oral arms. They host symbiotic algae (zooxanthellae) in their tissues, which photosynthesize and provide much of their nutrition – essentially making them solar-powered. They can release stinging mucus into the water even without direct contact.
Look for them in shallow, sandy areas with good sunlight penetration. They're often found in clusters near seagrass margins. Avoid touching them or disturbing the sediment nearby as they release stinging cells into the water. Excellent subjects for photography due to their stationary nature. Keep a respectful distance to avoid the irritating mucus they release.
Silver-cheeked Toadfish
A charismatic pufferfish with distinctive silver markings on its cheeks. Despite its invasive status, this curious and playful species has become a delightful encounter for divers in Cretan waters, often approaching to investigate bubbles and cameras.
Sandy and muddy bottoms, seagrass meadows, rocky reefs
The silver-cheeked toadfish entered the Mediterranean via the Suez Canal and was first recorded in Cretan waters around 2010. It has since become increasingly common along the north coast. While toxic if consumed (and illegal to sell in Greece), it poses no danger to divers and has become a favourite sighting due to its inquisitive nature.
Playful and remarkably curious, toadfish often approach divers to investigate, seemingly fascinated by bubbles and camera equipment. They're confident swimmers that hover in the water column, watching divers with their expressive eyes. Their endearing personality makes them memorable encounters despite their invasive status.
These friendly fish often approach on their own – stay still and let them come to you. They're particularly drawn to the sound of bubbles and may follow you throughout a dive. Great subjects for photography as they're not shy. Look for them over sandy areas and near seagrass beds. Their curious nature makes every encounter a joy.
Flounder
Masters of disguise, flounders are flat-bodied fish that lie motionless on sandy seabeds, their remarkable camouflage making them nearly invisible until they dart away. Both eyes migrate to one side of their body as they mature, a fascinating adaptation to life on the bottom.
Sandy bottoms, muddy seabeds, seagrass margins
The wide-eyed flounder (Bothus podas) is common in Cretan waters, particularly in the sandy bays around Almyrida and Georgioupoli. These bottom-dwellers have been part of Mediterranean ecosystems for millennia and are often spotted by observant divers scanning the seafloor. Local fishermen have long appreciated flounder for their delicate, sweet flesh.
Flounders are ambush predators that bury themselves in sand with only their protruding eyes visible. They can change color and pattern to match their surroundings with remarkable precision. When disturbed, they explode from the sand in a cloud of sediment, swimming with an undulating motion before settling again nearby.
Scan sandy bottoms very carefully – their camouflage is exceptional. Look for the subtle outline of their body or the telltale pair of elevated eyes. Move slowly to avoid startling them. Early morning dives when they're actively hunting offer better chances. The sandy areas near Koutalas and Ombros Gialos are prime flounder territory.
Scorpionfish
Masters of ambush, scorpionfish are perfectly camouflaged predators that blend seamlessly with rocky reefs. Their venomous spines and spectacular appearance make them both fascinating and formidable creatures of the Mediterranean.
Rocky reefs, caves, rubble bottoms
The red scorpionfish is a native Mediterranean species commonly found around Crete's rocky coastline, particularly at dive sites like Koutalas and the SS Minnewaska wreck. Known locally as 'skorpina,' it's prized in traditional Greek cooking for its firm, flavorful flesh and is the star ingredient in authentic fish soup (kakavia).
Scorpionfish are patient ambush predators that remain motionless for hours, waiting for prey to venture within striking distance. They can swallow fish nearly their own size in a single gulp. Despite their sedentary lifestyle, they're capable of remarkably fast strikes when prey approaches.
Look carefully on rocky surfaces and around the base of walls – their camouflage is exceptional. Never touch the substrate without looking first, as their venomous dorsal spines can cause painful stings. They're most active at dawn and dusk. Great subjects for macro photography due to their ornate features and willingness to stay still.
Striped Red Mullet
A classic Mediterranean bottom-dweller, the striped red mullet is instantly recognizable by its two long, whisker-like barbels and reddish-pink stripes. It uses these barbels to sift through sand and sediment for small crustaceans and worms, making it a fascinating subject for patient divers.
Sandy and rocky bottoms, seagrass meadows
The striped red mullet (Mullus surmuletus) is common in the shallow coastal waters around Crete, particularly near sandy bays and Posidonia meadows off Almyrida and Georgioupoli. It is a familiar sight on relaxed reef dives and a historically valued fish in Cretan cuisine.
Striped red mullet are bottom-feeders that use their sensitive barbels to probe sediment for food. They are often seen in small groups or pairs, rooting through the seabed with their snouts. When disturbed, they swim in short, darting bursts before settling back to the bottom.
Look down and scan sandy patches near rocky reefs or seagrass beds. Move slowly and avoid stirring up sediment, as this reduces visibility. They are easiest to photograph during the day when they are actively foraging.
Rainbow Wrasse
One of the most colourful fish in the Mediterranean, the rainbow wrasse is a small, energetic cleaner fish that zips around rocky reefs in vivid shades of green, blue, and orange. They are reliable companions on almost every Cretan dive.
Rocky reefs, seagrass beds, shallow coastal waters
The Mediterranean rainbow wrasse is abundant around Crete's rocky coast and Posidonia seagrass meadows. Their bright colours and busy behaviour make them a favourite subject for underwater photographers. They are especially numerous in the protected shallows of Ombros Gialos and Koutalas.
Rainbow wrasse are active cleaners, picking parasites and dead skin from larger fish. They are fast swimmers and fiercely territorial, darting in and out of crevices to defend their patch. Their colouration varies with age, sex, and mood, adding to their rainbow-like appearance.
Watch for them flitting around rocky outcrops and cleaning stations. They are bold enough to approach divers, but their rapid movements make them tricky to photograph. Use a fast shutter speed and stay calm. They are a great indicator of a healthy reef.
Dentex
A powerful silver predator with a reputation for speed and strength, dentex patrol deeper reefs and rocky drop-offs. Spotting one in Crete is a sign that the ecosystem is healthy and full of life.
Rocky reefs, deep drop-offs, wrecks
The common dentex is a prized Mediterranean game fish found in deeper Cretan waters, particularly around the rocky reefs of Kalami and the deeper sections of the Apokoronas diving park. Though shy, it is occasionally seen by advanced divers along walls and drop-offs.
Dentex are agile predators that hunt in small groups or alone, preying on fish, squid, and crustaceans. They are cautious and powerful swimmers, often vanishing into the blue when approached. Larger individuals are territorial and can live for more than 15 years.
Keep an eye on the blue as well as the reef. Dentex often patrol the edges of walls and deeper sections of the dive site, appearing suddenly before disappearing just as quickly. Staying relaxed and moving slowly will improve your chances of a memorable sighting.
Tuna
Fast, powerful, and built for speed, tuna are the open-water icons of the Mediterranean. Their sleek silhouettes racing through the blue are a thrilling reminder of the ocean's wild energy.
Open water, drop-offs, deep reefs
Several tuna species, including little tunny and Atlantic bluefin, pass through Cretan waters during warmer months. The deep waters off the north coast, especially around The Wall, can produce dramatic encounters as these pelagic hunters chase schools of baitfish.
Tuna are highly migratory, warm-blooded predators capable of maintaining high speeds over long distances. They hunt in fast-moving schools, often working with barracuda and amberjack to corner prey. Their metallic colouring and torpedo-shaped bodies reduce drag as they sprint through the water.
Tuna encounters are brief and exhilarating. Keep your eyes on the blue water during safety stops and along deep walls. Stay calm and avoid chasing them. If baitfish suddenly scatter, a tuna or barracuda may be nearby. The Wall and offshore boat dives offer the best chances.
Greater Amberjack
A muscular, silver predator with a dark diagonal stripe through the eye, the greater amberjack is a bold and inquisitive hunter. Encountering one on a drift dive is a true highlight for experienced divers in Crete.
Open water, deep reefs, wrecks, vertical walls
The greater amberjack is found in deeper Cretan waters, especially along the dramatic drop-offs of The Wall and around offshore wrecks. Strong, curious, and often approachable, these fish have become a signature sight for advanced divers exploring the north coast.
Amberjack are fast, powerful swimmers that often gather in small groups around wrecks, reefs, and drop-offs. They are opportunistic predators, feeding on smaller fish and squid. Curious individuals will follow divers, sometimes circling closely before vanishing into the blue.
Amberjack are most often seen on deep drift and wreck dives. Hold your position near the wall or wreck and let them come to you. Their curiosity can lead to close passes, making for spectacular video. Keep gear secure in strong currents, as they often appear when conditions are energetic.
