Maritime police have filmed five sperm whales, the largest of the toothed whales and the largest toothed predator, swimming in the Šibenik archipelago off Croatia’s Adriatic coast, Blue World Institute of Marine Research and Conservation said…
Despite their size, sperm whales are completely harmless to humans, but Blue World is advising citizens not to converge on the group due to the fact that they are probably upset because they are in an enclosed, shallow space, and that harassment may cause accidental stranding.
The institute aims to ensure the safe release of the sperm whales from shallow parts of the Adriatic, and asks the public to report any observation of them either via phone -051 604 666 or 091 4637424, or email [email protected].
The sperm whale’s, who normally live in deep water, clicking vocalization, a form of echolocation and communication, may be as loud as 230 decibels underwater,making it the loudest sound produced by any animal. It has the largest brain of any animal on Earth, more than five times heavier than a human’s, and can live for more than 60 years. Sperm whales are not a common sight in Croatia, with the last sighting of a group in 2009. (blue world)
