PYGMY KILLER WHALE2014
By Amelia Meyer
Scientific Name: Feresa attenuata
Other Names: Slender Blackfish, Slender Pilot Whale
Although the Pygmy Killer Whale is, technically, found in tropical and subtropical waters around the world, it is rarely seen in the wild. They are only a little bigger than the average dolphin and have been known to display aggressive behaviour towards both humans and other cetaceans when kept in captivity. It is unknown if this behaviour is also shown in the wild, although some body scarring indicates that it may well be.
The Pygmy Killer Whale is robust in front of the dorsal fin, but much more slender towards the rear of its body. The body colour ranges from a dark blue-black or grey to a brown-grey. There is a darker shade of colour on its back in front of the dorsal fin, known as a cape. There is a large white patch on the underside of the whale, which is bisected by a deep groove.
The dorsal fin is tall and concave and the pectoral fins long with rounded tips. The fluke (or tail fin) has a slight central notch and pointed tips.
