Which Sharks Are There in Croatia? 9 Common Adriatic Shark Species

As I mentioned above, Croatia is a country located along the Adriatic Sea, the body of water separating the Balkan Peninsula from the Italian Peninsula. The Adriatic Sea is known for its rich biodiversity, and its waters are home to several species of sharks. Let’s take a closer look at the Adriatic sharks found in Croatia.

Blue Shark

The blue shark (Prionace glauca) is a slender, long-distance swimmer often found in open waters. It can grow up to 3.8 meters in length and weigh up to 206 kg.

They prefer warm waters in the summer but migrate to colder ones in the winter.

Great White Shark

The great white shark (Carcharodon carcharias) is a large, predatory fish best known for its fearsome reputation. However, great white sharks are rare in the Adriatic and not commonly sighted in Croatia. They are mostly found in the Atlantic Ocean and the Mediterranean Sea, where temperatures are more suitable.

Bull Shark

The bull shark (Carcharhinus leucas) is a medium-sized species commonly found in coastal waters. They can grow up to 3.5 meters in length and weigh up to 316 kg. While bull sharks are known for their ability to swim in freshwater, they are still primarily saltwater sharks.

Do Sharks Attack in Croatia?

Shark attacks in Croatia are rare, but they can occur. The Adriatic Sea shark attacks have been monitored since 1868, making it one of the world’s longest-standing records of shark attacks. The United States Shark Research Institute from Princeton, New Jersey, is now responsible for maintaining these records.

According to the available data, there have been only 21 documented cases of shark attacks in Croatia in the last 135 years, with only 11 of these being fatal. This indicates that the frequency of shark attacks in Croatia is very low, especially compared to other regions. For instance, the United States recorded a staggering 47 unprovoked shark bites in 2021 alone.

Despite the low numbers, some factors may increase the incidence of shark attacks in Croatia. For example, the Adriatic Sea is relatively shallow compared to other parts of the world, and its waters can become quite warm in the summer months, which may increase the activity of some shark species.

Additionally, the tourism industry in Croatia has been booming in recent years, with many visitors drawn to its pristine beaches and crystal-clear waters. This increase in human activity, coupled with the presence of baited water sports equipment and the feeding of marine life, may attract sharks closer to the shore.

Most shark species are not dangerous to humans, and fatal attacks are extremely rare. In fact, sharks play a critical role in maintaining healthy marine ecosystems and are vital to the balance of our oceans. That being said, beachgoers need to take precautions, such as avoiding swimming at dawn or dusk when sharks are most active, staying in groups, and refraining from wearing shiny jewellery or brightly coloured clothing.
