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.
Once the stocks of larger species were depleted, orcas were targeted by commercial whalers in the mid-20th century. Between 1954 and 1997, Japan took 1,178 orcas (although the Ministry of the Environment claims that there had been domestic catches of about 1,600 whales between late 1940s to 1960s [213]) and Norway took 987.

Pilot whales are cetaceans belonging to the genus Globicephala. The two extant species are the long-finned pilot whale (G. melas) and the short-finned pilot whale (G. macrorhynchus). The two are not readily distinguishable at sea, and analysis of the skulls is the best way to distinguish between the species.
False killer whale breaching. The false killer whale is an apex predator, inhabiting tropical and subtropical waters. [32] [33] Generally, the false killer whale targets a wide array of squid and fish of various sizes during daylight hours. [9] [34] They typically target large species of fish, such as mahi-mahi, wahoo and tuna.

Six species of dolphins have the word "whale" in their name, collectively known as blackfish: the orca, or killer whale, the melon-headed whale, the pygmy killer whale, the false killer whale, and the two species of pilot whales, all of which are classified under the family Delphinidae (oceanic dolphins).

Toothed whales range in size from the 1.4 m (4 ft 7 in) and 54 kg (119 lb) vaquita to the 20 m (66 ft) and 100 t (98 long tons; 110 short tons) sperm whale. Several species of odontocetes exhibit sexual dimorphism, in that there are size or other morphological differences between females and males. They have streamlined bodies and two limbs ...
