The dwarf sperm whale, Kogia simus, is an shy animal and prefers to live a long way from shore, although specimens have been found stranded on beaches. Rarely seen at sea, except in extremely calm conditions, it is the smallest of the whales and is even smaller than some dolphins. Dwarf sperm whales reach a maximum size of about 8 feet, and weigh about 600 pounds. The body is bluish grey with a lighter underside and slightly yellow streaks. There is a white false gill behind each eye. The flippers are very short and broad. The top of the snout overhangs the lower jaw, and it has curved sharp teeth. The dwarf sperm whale has a spermaceti organ in its forehead, which is able to expel a dark reddish substance when frightened or attacked . Dwarf sperm whales live in deep, temperate, subtropical and tropical waters in both the northern and southern oceans, and feed primarily on squid and crab.
