Why Crete’s Underwater World Is So Exciting
Crete is Greece’s largest island, set in the heart of the eastern Mediterranean. Millions of travelers visit each year for its gorgeous beaches, ancient culture and warm hospitality. What many underestimate: the waters around Crete are a true marine paradise.
Anyone who swims, snorkels or dives will encounter a rich variety of fish, marine mammals, sea turtles and smaller sea creatures. Some are colorful and easy to spot, others are perfectly camouflaged and nearly invisible at first glance. For visitors, it’s helpful to know which animals live in the sea around Crete — and whether there are any species you should treat with care.
In this guide you’ll discover everything about marine life around Crete — from harmless reef fish to dolphins and sea turtles, practical tips for swimmers and snorkelers, and even rare encounters with whales.

Fish in the Sea Around Crete
Swim or snorkel in crystal-clear water and you’ll almost always meet colorful shoals of fish. Many are classic Mediterranean species that thrive in rocky coves and seagrass meadows.
The Most Common Fish Species
-
Seabream (Sparidae): Among the most common families. The salema bream (Sarpa salpa) stands out with its golden stripes.
-
Painted comber (Serranus scriba): A curious fish often cruising near the shore among rocks, with distinctive blue markings.
-
Wrasses: Small, colorful fishes common along rocky coastlines — easy to spot while snorkeling.
-
Parrotfish: Brightly colored and unmistakable — also found in Cretan waters.
-
Barracuda: Sleek, silvery hunters. They may look intimidating but are harmless to humans, often seen in groups.

Fish of Interest to Anglers
Crete also attracts anglers. Seabream, tuna and mackerel are popular targets. In some areas, you can join fishing trips — either offshore by boat or from the shoreline.
Marine Mammals: Dolphins and Monk Seals
Dolphins off Crete
Dolphins are widespread in the Mediterranean, including around Crete. The common bottlenose dolphin (Tursiops truncatus) inhabits coastal waters here. Playful and curious, they often leap from the sea. With a bit of luck, visitors spot them on boat trips — especially in the south and in the area between Crete and the Cyclades.
Mediterranean Monk Seal
A true rarity is the Mediterranean monk seal (Monachus monachus), one of the world’s most endangered seal species. Small colonies live in Crete’s remote caves and coves. Sightings are extremely rare but possible — especially along the island’s west and south coasts.
Sea Turtles — the Famous Caretta caretta
Crete is one of the Mediterranean’s most important nesting sites for the loggerhead sea turtle (Caretta caretta).
-
Nesting beaches: Especially along the north coast near Rethymno and Chania, and in Messara Bay in the south.
-
Sightings in the water: While snorkeling or swimming you may see them gliding calmly through the sea.
Important note for visitors:
-
Keep your distance — do not touch or feed turtles.
-
On marked nesting beaches (often protected by WWF), avoid lights at night and don’t place sunbeds there.
Jellyfish in the Waters Around Crete
Many travelers ask: Are there dangerous jellyfish in Crete?
The good news: jellyfish do appear, but most are harmless.
-
Moon jellies: Transparent, often with a bluish sheen — generally harmless.
-
Mauve stinger (Pelagia noctiluca): Can appear sporadically, especially in high summer. The sting is painful but not life-threatening.
Tip: If you spot jellyfish, keep your distance. Lifeguards sometimes issue small advisories at the beach.
Sea Urchins and Other Bottom Dwellers
Sea Urchins
Very common in rocky coves. If you go barefoot, their spines can hurt. Tip: wear water shoes.
Moray Eels
They live in rock crevices and caves. They look menacing, but are shy and won’t attack unless provoked.
Octopus and Cuttlefish
Cretan waters are rich in cephalopods. Octopus are masters of camouflage and fascinating to watch — divers see them especially often.
Scorpionfish
Extremely well-camouflaged bottom fish. Their spines are venomous but not life-threatening to humans. Be careful when walking barefoot or snorkeling near rocks.
Sharks and Large Fish off Crete
A topic that interests many visitors: Are there sharks around Crete?
Yes, but: most Mediterranean sharks are harmless and shy.
-
Catsharks: Small bottom-dwelling sharks — completely harmless.
-
Blue shark: Lives in deeper waters, rarely near shore.
-
Large sharks: In theory, bigger species such as the great white exist in the Mediterranean, but sightings are extremely rare — virtually unheard of off Crete.
Whales off Crete
Rare, but possible:
-
Sperm whales: Migrate through the deep waters south of Crete.
-
Fin whales: Also occasional visitors to the Mediterranean.
If you want to see whales, book dedicated boat trips — sightings are much rarer than dolphins.

-
Mini crabs and shrimp in the shallows.
-
Small fish in schools — often right between your legs while you’re bathing.
