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.
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]
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 ...
The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
The term "Great Whales" covers those currently regulated by the International Whaling Commission: [8] the Odontoceti family Physeteridae (sperm whales); and the Mysticeti families Balaenidae (right and bowhead whales), Eschrichtiidae (grey whales), and some of the Balaenopteridae (Minke, Bryde's, Sei, Blue and Fin; not Eden's and Omura's whales).
However, this value lowered to ~12.1 m if aquarium whale sharks were included. [6] • The 'large adult' silhouette is based primarily on measurements of a whale shark reported by Kaikini et al. (1959) and inspired by images of large females seen around the Galapagos. [7] • The largest size possible for whale sharks is uncertain.
The ancient shark, which grew up to 65ft long and weighed over 50 tons, ate sperm whales by ripping off their heads with its huge teeth, a new study has shown. The ancient shark, which grew up to ...
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.
