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 ...
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 .
A female bottlenose dolphin performing with her trainer. They are considered one of the most intelligent cetaceans. Cetacean intelligence is the overall intelligence and derived cognitive ability of aquatic mammals belonging in the infraorder Cetacea (cetaceans), including baleen whales, porpoises, and dolphins.
A Wholphin. The first recorded wholphin was born in a Tokyo SeaWorld in 1981; he died after 200 days. [4]The first wholphin in the United States and the first to survive was Kekaimalu, born at Sea Life Park in Hawaii on May 15, 1985; her name means "from the peaceful ocean". [4]
Large whales tend to lobtail by positioning themselves vertically downwards into the water and then slapping the surface by bending the tail stock. Dolphins, however, tend to remain horizontal, either on their belly or their back, and make the slap via a jerky whole body movement. All species are likely to slap several times in a single session.
A common bottlenose dolphin (Tursiops truncatus). A dolphin is an aquatic mammal in the clade Odontoceti (toothed whale).Dolphins belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and possibly extinct Lipotidae (baiji or Chinese river dolphin).
The common dolphin (Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. [3] Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media.
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).
