This includes the sperm whale, oceanic dolphins, usually pilot and Orcas, and a few beaked whale species. The most common species to strand in the United Kingdom is the harbour porpoise ; the common dolphin ( Delphinus delphis ) is second-most common, and after that long-finned pilot whales ( Globicephala melas ).
The sperm whale's eye does not differ greatly from those of other toothed whales except in size. It is the largest among the toothed whales, weighing about 170 g. It is overall ellipsoid in shape, compressed along the visual axis, measuring about 7×7×3 cm. The cornea is elliptical and the lens is spherical.
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
Orcas are versatile predators with many populations actively hunting down whales such as the Grey Whale....the Sperm Whale, at 18 metres long, is the largest toothed animal to have ever lived....in spite of their enormous mass, baleen whales are capable of leaping completely out of the water, particularly the Humpback Whale
Sperm whale stranded on a beach in Spain. Macro-waste varies enormously in size, from abandoned fishing nets hundreds or even thousands of meters long [57] – a death trap for even the largest whales – to microscopic microplastics suspended in the water
Sperm whales are listed as an endangered species in the U.S. Eventually, the whale's carcass is likely to be either towed out to sea, taken to a landfill or buried, officials said.
What sperm whales are saying with their clicks remains a mystery to human ears. Still, uncovering the scope of whales’ vocal exchanges is an important step toward linking whale calls to ...
