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.
The whale was fed "100 pounds (45 kilograms) of fish, mostly ling cod and herring, in four daily feedings." [176] Weighing approximately 3,000 pounds (1,400 kilograms) [177] and "just under 15 feet (4.6 metres)" long, this was still an immature orca, whose dorsal fin could not yet indicate gender.
Orcas. Orcas are large, active and intelligent. Males range from 6 to 9.7 m (20 to 32 ft) and can weigh over 8 tonnes (8.8 tons), while females range from 5 to 7 m (16 to 23 ft) and weigh 3 to 5 tonnes (3.3 to 5.5 tons). [5] The orca is the largest species of the dolphin family.
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.

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 ...
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 false killer whale ( Pseudorca crassidens) is a species of oceanic dolphin that is the only extant representative of the genus Pseudorca. It is found in oceans worldwide but mainly in tropical regions. It was first described in 1846 as a species of porpoise based on a skull, which was revised when the first carcasses were observed in 1861.
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.
