Orca gladiator (Bonnaterre, 1789) The orca ( Orcinus orca ), or killer whale, is a toothed whale that is the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus. Orcas are recognizable by their black-and-white patterned body.
Tilikum was the largest orca in captivity. [8] He measured 22.5 feet (6.9 m) long and weighed about 12,500 pounds (5,700 kg). [9] His pectoral fins were 7 feet (2.1 m) long, his fluke curled under, and his 6.5-foot-tall (2.0 m) dorsal fin was collapsed completely to his left side.
The humpback whale ( Megaptera novaeangliae) is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera. Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons). The humpback has a distinctive body shape, with long pectoral fins ...
Pitman, who has studied killer whales in Antarctica for over 10 years, said there's a similar divide between mammal- and fish-eating killer whales in those waters.
The most common natural predator of sperm whales is the orca (killer whale), but pilot whales and false killer whales sometimes harass them. [194] [195] Orcas prey on target groups of females with young, usually making an effort to extract and kill a calf. The females will protect their calves or an injured adult by encircling them.
The fin whale ( Balaenoptera physalus ), also known as the finback whale or common rorqual, is a species of baleen whale and the second-longest cetacean after the blue whale . The biggest individual reportedly measured 26 m (85 ft) in length, with a maximum recorded weight of 77 to 81 tonnes. The fin whale's body is long, slender and brownish ...
The groups near to or under the sea ice have a degree of protection, as the killer whale's large dorsal fin, up to 2 m in length, impedes their movement under the ice and does not allow them to get sufficiently close to the breathing holes in the ice. [39] Beluga whale behavior under killer whale predation makes them vulnerable to hunters.
Man is fined for trying to 'body slam' killer whale. ... Orca, whose numbers in New Zealand are estimated to be between 150 and 200, are apex predators that can weigh 12,000 pounds or more.
