Sharks and Dolphins in Zante: Your Complete Guide to Marine Life in Zakynthos Waters

Are you planning a trip to the stunning Greek island of Zante (Zakynthos) and wondering about the marine life you might encounter? This comprehensive guide answers all your questions about sharks and dolphins in Zante's crystal-clear Ionian Sea waters.

Are There Sharks in Zante, Greece?

The short answer: Yes, but shark encounters are extremely rare and poses virtually no danger to swimmers.

Shark sightings in Zakynthos are extremely rare, with most interactions being benign. Greek marine biology experts confirm that while about 35 shark species are found in Greek waters, they exist in very, very low concentrations throughout the Mediterranean.

Shark Species Found Around Zante

The Mediterranean Sea around Zakynthos is home to several shark species, though sightings remain exceptionally uncommon:

Common Harmless Species:

• Basking Shark - The largest species found in Greek waters, completely harmless as it feeds on plankton

• Thresher Shark - Generally harmless and stays in deeper waters

• Spiny Dogfish - Sometimes ventures into shallow waters off the Greek coast but has no interest in humans

• Catshark - Part of the approximately 200 fish species variety in Zakynthos waters

Rare Visitors:

• Blue Shark - Might visit but rarely meets humans

• Shortfin Mako - Occasionally spotted but prefers deeper, offshore waters

• Great White Shark - The species most commonly associated with shark attack incidents in Greece, although this species is rare in Greek waters

How Dangerous Are Sharks in Zante Waters?

Shark attacks in Greece are remarkably rare. Over a 180-year period (1847-1981), there were only 15 total recorded shark attack incidents in all of Greece, with the last recorded incident occurring in 1981. More specifically:

• In the past 170 years, there have been only 15 shark attacks and one fatality in Greek waters

• The Ionian Sea, which surrounds Zante, has not had any confirmed shark attacks

• No shark attacks have been reported in Greece for about seven decades, with the last attack occurring in 1953 in Corfu

Why Are Sharks So Rare in Zante?

Several factors contribute to the low shark populations around Zakynthos:

1. Water Temperature and Nutrients: The warm but nutrient-poor waters mean sharks are not common in the Mediterranean

2. Habitat Preference: Sharks like deeper, colder waters where they usually hunt fish, seals, squid and other marine animals

3. Conservation Concerns: About 50% of shark and ray species in the Mediterranean face extinction due to overfishing and getting caught in fishing gear

Dolphins in Zante: A Magical Marine Experience

Unlike sharks, dolphins are commonly spotted in the waters around Zakynthos and offer visitors magical encounters.

Dolphin Species Around Zante

Visitors to Zakynthos can see dolphins, including common and bottlenose dolphins, which live in the waters around Kefalonia and Ithaca in the wider Ionian Sea region.

Primary Species:

Bottlenose Dolphins (Tursiops truncatus)

• Can grow up to 4.1 meters long

• The archetypical "Flipper" - tends to prefer shoaling and bottom-dwelling species, feasting upon a wide variety of fish, squid and octopi

• A distinctly social species, usually travelling in groups of as many as a dozen, but have been seen in aggregations of several hundred

• The cetacean species most frequently found in coastal Mediterranean waters

Common Dolphins (Delphinus delphis)

• Smaller but can swim fast, over 60 km/h

• Can be recognised by their hourglass lateral pattern, with a buffy-beige, almost yellow anterior zone and a bluish-gray posterior zone

• Very sociable dolphins, enjoying the company of boats, especially sailboats

Striped Dolphins (Stenella coeruleoalba)

• Named after their dark bluish-black stripe running across the entire length of the body

• In the east Mediterranean, the Striped dolphin is the most common and most sighted dolphin

Risso's Dolphins (Grampus griseus)

• Usually seen in groups of 3-30 animals, and often mix with other dolphin species

• Characterised by dark skin almost always streaked with long, light scars, which can turn older individuals completely white

Dolphin Behavior and Interactions

Dolphins are beautiful sea mammals that enjoy interaction with humans often choosing to swim alongside boats. Anyone who has seen dolphins knows what majestic creatures they are and how impressive it is to see their power and grace as they dip in and out of the water.

What to Expect:

• Dolphins frequently approach boats and may swim alongside vessels

• They often surface leisurely side-by-side but when moving quickly are aerial acrobats and often breach, bowride and porpoise

• Best spotted during boat trips rather than from shore

• Most active during early morning and late afternoon

Conservation Status of Dolphins in Greek Waters

Conservation is crucial for maintaining healthy dolphin populations:

• Mediterranean bottlenose dolphins are currently classified as Vulnerable in IUCN Red List

• Common dolphins were classified as Endangered in the IUCN Red List in 2003, having declined throughout the Mediterranean since the 1960s

• Common dolphin numbers have dropped significantly in recent decades, showing the big challenges marine ecosystems face

Threats include:

• Incidental mortality in fishing gear, prey depletion caused by overfishing, habitat degradation, boat traffic, noise, and health effects caused by pollution

Other Marine Life in Zante Waters

Zakynthos offers incredibly rich marine biodiversity beyond sharks and dolphins:

Sea Turtles

• Loggerhead Turtles (Caretta caretta): Perhaps the easiest of all marine animals to find, best seen during April, May, and June in the bay of Laganas

• The Southern coast of Zakynthos is the favourite breeding area of the sea turtle Caretta Caretta

Mediterranean Monk Seals

• Zakynthos is the permanent home to around 15 seals, which have taken up residence in the caves on the west coast

• With just over 600 animals left in the wild, this truly is a rare breed of seal

Rich Marine Ecosystem

The rich and varied marine life in Zakynthos includes octopus, barracuda, moray eels, large grouper, tuna, crayfish, langusta, white bream, bluefish, greater amberjacks, parrotfish and many other reef fish.

Swimming Safety in Zante Waters

Swimming in Zante is exceptionally safe regarding marine life encounters:

Shark Safety

• Shark encounters are minimal, with a low level of associated danger

• People who swim where they would normally swim have no reason to be concerned

• Sharks here are not interested in humans, focusing on their natural prey

General Water Safety

• Crystal clear waters with visibility ranging from 20-40 meters make conditions ideal for swimming and snorkeling
