Melon-headed whales are dark gray to black with a pointed snout, rounded head, and a narrow white to gray patch around the lips sometimes called a "sad face" marking.
Adults typically measure 8.2 to 9 feet in length and weigh between 350 and 460 pounds, one of the smaller members of the blackfish group.
Melon-headed whales are sometimes called "electra dolphins," but despite the name they belong to the same blackfish group as pilot and false killer whales.
Melon-headed whales inhabit deep tropical and subtropical offshore waters worldwide, rarely venturing close to shore except where the seafloor drops off quickly.
They feed primarily on small squid and fish, hunting cooperatively at depth, often at night when prey rises toward the surface.
Melon-headed whales travel in some of the largest pods of any cetacean, from a few hundred to well over a thousand individuals, sometimes mixed with other dolphin species.
