Two pilot whales in the Indian Ocean

Pilot whales are two species of oceanic dolphins, whose scientific name is Globicephala. The two types of pilot whales are the long-finned pilot whale and the short-finned pilot whale. Their behaviour resembles that of the larger whales more than that of dolphins.

The two look similar at sea and are usually just known simply as pilot whales or calderón in Spanish. They and other large dolphins are also known as blackfish.
