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.
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family.

A cosmopolitan species, it inhabits a wide range of marine environments, from Arctic to Antarctic regions to tropical seas.
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).

An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species.
