Orcas may attain larger sizes as males have been recorded at 9.8 m (32 ft) and females at 8.5 m (28 ft). [32] Large males can reach a weight of over 10 tonnes (9.8 long tons; 11 short tons). [33] [34] Calves at birth weigh about 180 kg (400 lb) and are about 2.4 m (7.9 ft) long.
Orcinus is a genus of Delphinidae, the family of carnivorous marine mammals known as dolphins. It includes the largest delphinid species, Orcinus orca, known as the orca or killer whale. Two extinct species are recognised, Orcinus paleorca and O. citoniensis, describing fossilised remains of the genus. [2]
Type A or Antarctic orcas look like a "typical" orca, a large, black-and-white form with a medium-sized white eye patch, living in open water and feeding mostly on minke whales. [ 2 ] [ 4 ] Type B1 or pack ice orcas are smaller than type A. [ 4 ] It has a large white eye patch.
This image assumes an average length of 4.6 metres for a great white shark (males measure 3.4 to 4.0 m (11 to 13 ft), and females measure 4.6 to 4.9 m (15 to 16 ft) on average), and 6.5 metres for a killer whale (males typically range from 6 to 8 metres (20 to 26 ft) and females from 5 to 7 m (16 to 23 ft). Hence, a killer whale is on average 1 ...
False killer whales are large marine predators. They are the fourth-largest extant species of oceanic dolphin, exceeded in size only by the orca, and the two species of pilot whales. Females reach a maximum size of 5 m (16 ft) in length and 1,200 kg (2,600 lb) in weight, and males 6 m (20 ft) long and 2,300 kg (5,100 lb).
The skull of the leopard seal. The leopard seal has a distinctively long and muscular body shape when compared to other seals. The overall length of adults is 2.4–3.5 m (7.9–11.5 ft) and their weight is in the range 200 to 600 kilograms (440 to 1,320 lb), making them the same length as the northern walrus but usually less than half the weight.
Wild orcas can travel up to 62 miles a day, but captive orcas are held in tanks equivalent to a bathtub. ... See if you can tell the difference between real killer whales and look alike marine ...
Thus, biologists have since used skull differences to distinguish the two species. [3] [4] The size and weight depend on the species, as long-finned pilot whales are generally larger than short-finned pilot whales. [12] [13] Their lifespans are about 45 years in males and 60 years in females for both species. Both species exhibit sexual dimorphism.
