Pygmy Killer Whale

The pygmy killer whale is a small, robust oceanic dolphin with a rounded head, no distinct beak and a dark cape that contrasts with paler flanks. A narrow white line may occur around the mouth. Adults are approximately 2.1–2.6m long. The species inhabits deep tropical and subtropical waters worldwide. (Wikipedia, general species account)

It feeds on fish and squid and usually travels in cohesive groups ranging from several animals to a few dozen. At sea it may be confused with melon-headed whales, but its rounded flippers, more robust build and characteristic head pattern help separate it. (Wikipedia, general species account)
