This is because the density of water is much greater than that of air and they are able to travel faster by leaping out of the water. ...both whales and dolphins carry ‘ whale lice ’ — small crustaceans that inhabit folds in the skin of whales and dolphins, feeding off the loose skin.
There are approximately 89 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 whale ...
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 ...
Researchers have warned that human impact on the ocean is putting increasing pressure on dolphins and whales, and their ecosystems. The UK whale and dolphin conservation charity Orca recorded ...
Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea.Close to forty extant species are recognised. They include several big species whose common names contain "whale" rather than "dolphin", such as the Globicephalinae (round-headed whales, which include the false killer whale and pilot whale).
There are also fewer than ten pilot whales, Amazon river dolphins, Risso's dolphins, spinner dolphins, or tucuxi in captivity. Two unusual and rare hybrid dolphins, known as wolphins , are kept at Sea Life Park in Hawaii , which is a cross between a bottlenose dolphin and a false killer whale .
As a result, phytoplankton levels are low, and the pelagic ecosystem is less dense than in other oceanic regions. This explains why cetaceans, and whales in particular, are mainly found near rivers and outlets (Alboran Sea, Aegean Sea) and in areas where deep currents resurface, such as the Ligurian Sea. [2]
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 ...
