However, the amount of fish taken is very little compared to what the sperm whale needs per day. Video footage has been captured of a large male sperm whale "bouncing" a long line, to gain the fish. [163] Sperm whales are believed to prey on the megamouth shark, a rare and large deep-sea species discovered in the 1970s. [164]
Brygmophyseter, known as the biting sperm whale, is an extinct genus of toothed whale in the sperm whale family with one species, B. shigensis. When it was first described in 1994, the species was placed in the genus Scaldicetus based on tooth morphology , but this was later revised in 1995.
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 ...
This places the beaked whales as some of the few food competitors of the sperm whale. Other possible squid predators include the pilot whale , killer whales , larger southern elephant seals , Patagonian toothfish , [ 40 ] southern sleeper sharks ( Somniosus antarcticus ), Antarctic toothfish , and albatrosses (e.g., the wandering and sooty ...
Sharkbook is a global database for identifying and tracking sharks, particularly whale sharks, using uploaded photos and videos.In addition to identifying and tracking sharks, the site allows people to "adopt a shark" and get updates on specific animals.
English: The size and growth of the whale shark (Rhincodon typus), represented by various individuals reported in the literature.A small 55 centimetres (22 in) pup, a 5.62 metres (18.4 ft) juvenile, a generic 9 metres (30 ft) young adult, a large 12.1 metres (40 ft) adult, and an exceptionally large adult with a precaudal length of 15 metres (49 ft).
Offshore orcas feed on sharks and larger fish in deeper water still, rarely, if ever, coming close to the shore. The researchers collected examples and evidence of killer whales traveling even ...
They have also been reported to eat some deep-sea shrimps, but, compared with dwarf sperm whales, relatively few fish. [9] Predators may include great white sharks [28] and killer whales. [29] Pygmy sperm whales and dwarf sperm whales are unique among cetaceans in using a form of "ink" to evade predation in a manner similar to squid.
