Peponocephala electra 

At birth and is 1 meter (3 ft) long. An adult grows up to 3 meters (10 ft) long. Weighs in excess of 200 kilograms (440 lb)

The melon-headed whale, Peponocephala electra, is found in tropical and subtropical waters worldwide, most commonly in the Philippine Sea. They favor warm, pelagic waters. Melon-headed whales travel in pods of 100-1,000, although even larger pods have been reported.

The Melon-headed Whale has a body shape rather like a torpedo - its head shaped like a rounded cone giving the animal its common name. The body is more or less uniformly light grey except for a dark grey face - sometimes called the "mask". The flippers are long and pointed. The dorsal fin is tall with a pointed tip - reminiscent of its cousin the Orca. When viewed in profile the head is not as rounded as the Pygmy Killer and this may be an aid to identification.
This whale is capable of swimming very quickly, particularly when startled. When doing so it often makes short low jumps clear of the sea surface, causing lots of splash. Melon-heads usually gather in large numbers (at least 100 and possible as many as 1000 on rare occasions) and sometimes strand together.

The Melon-head weighs about 10-15 kilograms (22-33 lb) at birth and is 1 meter (3 ft) long. An adult grows up to 3 meters (10 ft) long and weighs in excess of 200 kilograms (440 lb). The whales' lifespan is at least 20 years and probably more than 30 years for females. Their primary diet is squid.
