Dusky dolphins mainly feed on fish and squid. Common fish species eaten include anchovies, lantern fish, pilchards, sculpins, hakes, horse mackerel, hoki and red cod, while squids preyed on include those of the genera Nototodarus, Todarodes and Loligo. [13]
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).
Although oceanic dolphins are widespread, most species prefer the warmer waters of the tropic zones, but some, like the right whale dolphin, prefer colder climates. Some have a global distribution, like the orca. Oceanic dolphins feed largely on fish and squid, but a few, like the orca, feed on large mammals, like seals.
Dolphin meat is high in mercury, and may pose a health danger to humans when consumed. [17] Ringed seals were once the main food staple for the Inuit. They are still an important food source for the people of Nunavut [18] and are also hunted and eaten in Alaska. Seal meat is an important source of food for residents of small coastal communities ...
Scientists found that members of the new species are smaller than their offshore common bottlenose counterparts, eat different fish and have spines adapted to navigating the tight spaces of rivers ...
The spinner dolphin feeds mainly on small mesopelagic fish, squids, and sergestid shrimps, and will dive 200–300 m to feed on them. [14] Spinner dolphins of Hawaii are nocturnal feeders and forage in deep scattering layers, which contain many species. The dwarf spinner dolphin may feed mostly on benthic fish in reefs and shallow water. [7]
Individual members then take turns plowing through the ball, feeding on the stunned fish. [52] Coralling is a method where dolphins chase fish into shallow water to catch them more easily. [52] Killer whales and bottlenose dolphins have also been known to drive their prey onto a beach to feed on it.
Emperor penguins eat mostly fish but also supplement their diets with krill, other crustaceans, and squid. Like other penguin species, emperor penguins are equipped with a spiky tongue for help ...
