A explanation

of how this new species of orca is different from others and where it is found.

It has a smaller eyepatch, a fainter saddle, and a more bulbous head as compared to other orcas.

Explanation:

The regular orca, type A, has a more streamlined shape to its head, with a large eyepatch and a bold white saddle (the white part behind their dorsal fin), whereas the new species of orca, type D, or the sub-antarctic orca, has a rounder, shorter head, tiny eyepatches (the white spot above their eye) and a faint saddle behind their dorsal fin.
