A variety of whale species possess large physical brains, which are relatively small compared to their body size, [31] and also have very low neural density when contrasted with terrestrial species. [32] Fin whales, humpback whales and sperm whales have been found to have spindle neurons, whose function is not well understood, which is a type ...
Humpback whales in the sanctuary. Almost two-thirds of North Pacific humpback whales (estimates range from 4,000 to 10,000 whales) migrates to Hawaiian waters each winter to bear and nurse their calves and to mate, although not to eat. Their throats are only the size of a large dinner plate or a volleyball.
Coronula diadema is a species of whale barnacle that lives on the skin of humpback whales and certain other species of whale. [2] This species was first described by Carl Linnaeus in the 1767 12th edition of his Systema Naturae. [1]
Pods of female sperm whales sometimes protect themselves by forming a protective circle around their calves with their flukes facing outwards, using them to repel the attackers. [89] There is also evidence that humpback whales will defend against or mob orcas who are attacking either humpback calves or juveniles as well as members of other species.
There are approximately 89 [8] living species split into two parvorders: Odontoceti or toothed whales (containing porpoises, dolphins, other predatory whales like the beluga and the sperm whale, and the poorly understood beaked whales) and the filter feeding Mysticeti or baleen whales (which includes species like the blue whale, the humpback ...
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). [8] Solitary species naturally do not strand en masse. Cetaceans that spend most of their time in shallow, coastal waters almost never mass ...
During this feeding season humpback whales actively feed for up to twenty-two hours a day. [4] They do this so they can store enough fat reserves to live through their breeding season when they do not eat at all. [4] Humpback whales typically spend summer months in feeding grounds with cooler waters that they return to every year. [5]
