Long-finned Pilot Whale
Globicephala melas
Similar species
Very similar to Short-finned Pilot Whale, but the distribution of the two species is only thought to slightly overlap. The only obvious physical difference is the flipper length, hence the common names. Also similar to False Killer Whale.
Identification
Practically indistinguishable from Short-finned Pilot Whale in the field. The species has a broad-based dorsal fin placed far forward on the body that varies in size and shape from triangular and falcate in young, to large and rounded in adult males. Overall body colour is brownish-black to slate grey and a whitish or grey saddle is present behind the dorsal fin. Note, animals with extensive white markings behind the dorsal fin are confined to the Antarctic. Those occurring closer to the Australian mainland lack such distinctive marking. A grey to brownish elongate streak is often present behind and above the eye. An anchor-shaped whitish patch on the underside between the flippers may be visible at times. The broad melon is noticeably swollen and overhangs the lips. They form small, social groups of 10-50 animals but may also form schools of hundreds. Pilot whales usually undertake short dives lasting from about 1 to 10 minutes. Groups may log at the surface for long periods and may also associate with other whales and dolphins.
