The name implies a hybrid of whale and dolphin, though taxonomically, both are in the oceanic dolphin family, which is in the toothed whale clade. This type of hybrid was considered unexpected given the sometimes extreme size difference between a female common bottlenose dolphin (typically 2 meters long and 300 kilograms) and a male false ...
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 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 ...
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).
The monodontids, oceanic dolphins (Delphinidae) and porpoises (Phocoenidae) together comprise the Delphinoidea superfamily. Genetic evidence suggests the porpoises are more closely related to the white whales, and these two families constitute a separate clade which diverged from the Delphinidae within the past 11 million years.
The bottlenose dolphin is a toothed whale in the genus Tursiops.They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus contains three species: the common bottlenose dolphin (Tursiops truncatus), the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and Tamanend's bottlenose dolphin (Tursiops erebennus).
An Atlantic white-sided dolphin off the coast of Cape Ann, Massachusetts. The Atlantic white-sided dolphin is a small delphinid. At birth, calves measure just over a meter long; adult males grow to about 2.8 m (9.2 ft), and females to about 2.5 m (8.2 ft), [3] weighing between 180–230 kg (400- 510 lb) once fully grown. [3]
This dolphin is found mainly in the Alboran Sea and the north-western Mediterranean [13] [14] [17] [34] where its population is estimated at between 3,000 and 5,000 individuals. [2] The other pilot whale species, the long-finned pilot whale (G. macrorhynchus), seems to have been seen at least once in the Mediterranean, probably as a stray group ...
