In an intriguing development for marine biologists and shark enthusiasts alike, a thresher shark has been observed in the Gulf of Trieste, according to a report from the Miramare Marine Protected Area. This species, typically found in tropical waters, has ventured into Italian seas, showcasing its remarkable adaptability.
The thresher shark is distinguished by its exceptionally long tail, which is equal in length to the rest of its body. This feature is not just a striking physical trait but serves as a crucial tool for hunting. The tail functions like a sword, slicing through the water and allowing the shark to herd schools of fish. This technique enables the thresher shark to pass through dense fish populations without scattering them.
Marine experts highlight that recent studies have revealed another fascinating aspect of the thresher shark’s hunting strategy. The tail is also employed to stun prey, which predominantly includes small pelagic fish such as sardines and mackerel. This behavior has been documented through the frequent recovery of thresher sharks caught on longline hooks by their tails.
The thresher shark was spotted near an oceanographic buoy in the Gulf of Trieste, raising new questions about its migration patterns and the environmental factors influencing its presence in these waters. This sighting underscores the importance of ongoing research into the migratory behaviors of marine species and their interactions with different ecosystems.
