Offshore deaths of multiple whales are unlikely to lead to multiple strandings, since winds and currents are variable and will scatter a group of corpses. Most carcasses never reach the coast, and are scavenged , or decompose enough to sink to the ocean bottom, where the carcass forms the basis of a unique local ecosystem called a whale fall .
Before extensive research on whale vocalizations was completed, the low-frequency pulses emitted by some species of whales were often not correctly attributed to them. Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...
Cuvier's beaked whale, goose-beaked whale, or ziphius (Ziphius cavirostris) is the most widely distributed of all beaked whales in the family Ziphiidae. [7] It is smaller than most baleen whales —and indeed the larger toothed cetaceans (like orca and sperm whales )—yet it is large among the beaked whales and smaller cetaceans, appearing ...
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
Strandings of sperm whales have occurred across much of their global range. About 60 per cent of the world's recorded sperm whale strandings occur in three regions – Tasmania, New Zealand and the North Sea. [1] 132 strandings of sperm whales were recorded around the coast of the United Kingdom (mostly in Scotland) between 1990 and 2011. [2]
A dramatic operation to save the lives of more than 100 pilot whales ended in partial success on Thursday after wildlife officials managed to return most of the stranded animals to sea.
The degenerative disease might contribute to the mass strandings of some dolphins and other toothed whales, researchers said. ... Whales, dolphins and porpoises have been stranding in greater ...
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
