HWDT works 'directly with local communities to ensure whales, dolphins and porpoises are protected and valued throughout Scotland's west coast.' [5] Much of their data is collected through citizen science from members of the public as well as local boat tour operators and fishermen. [3]
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).
[9] 14 species of marine mammals including killer whales, Peale's dolphins, Commerson's dolphins, leopard seals, southern elephant seals, and southern sea lions frequent the surrounding waters. [12] Elephant seals, fur seals, and sea lions all breed on the islands, and the largest elephant seal breeding site has over 500 animals in it. [13]
Davina the Dolphin (formerly Dave the Dolphin) was a sociable solitary dolphin who resided off the coast in the Folkestone and Hythe area of England for approximately eighteen months. [1] This was a very unusual situation as dolphins normally reside with family groups known as pods, and are not usually seen on their own. [ 2 ]
The British Isles have few endemic species due to past frequent glaciations and because of the proximity to Continental Europe and former land bridges which enabled species to re-colonise the islands from the continent following glaciations. [1]
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).
The clymene dolphin (S. clymene) is the only confirmed case of hybrid speciation in marine mammals, descending from the spinner dolphin (S. longirostris) and the striped dolphin (S. coeruleoalba). [6] Stenella dolphins tend to be more active during nighttime and spend their daytime resting. Although these dolphins are supposed to spend 60% of ...
