Through this, environment plays a large role in the differentiation and evolution of this dolphin species. [87] The divergence and speciation within bottlenose dolphins has been largely due to climate and environmental changes over history. According to research, the divisions within the genus correlate with periods of rapid climate change.
Pliodelphis (meaning "Pliocene dolphin") is a genus of small delphinid (oceanic dolphin) cetaceans that lived in Belgium during the Early Miocene epoch, about 5 million to 4.4 million years ago. The genus contains the type species Pliodelphis doelensis , named and described in 2021 based on a partial skull recovered from the littoral Kattendijk ...
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 snubfin dolphins (Orcaella) contain two of the 35 species of oceanic dolphins that make up the Cetacean family of Delphinidae. [5] The phylogenetic status of Orcaella has long been confused. Although the snubfin dolphins share similar external features with the Monodontidae (narwhal), [ 2 ] a genetic study conducted by Arnason and ...
It includes all modern oceanic dolphins, porpoises, and their relatives, such as Lipotidae [2] and Iniidae. [ 3 ] [ 1 ] [ 4 ] [ 5 ] Short-beaked common dolphin (Delphinus delphis)
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).
Dolphins and other smaller cetaceans are sometimes hunted in an activity known as dolphin drive hunting. This is accomplished by driving a pod together with boats, usually into a bay or onto a beach. Their escape is prevented by closing off the route to the ocean with other boats or nets.
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. [3] 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).
