False Killer Whale

The false killer whale is a large oceanic dolphin, the fourth largest after the orca and the two pilot whales. It is black or dark grey, slightly lighter below, with a slender body, an elongated tapered head with no beak, a sickle-shaped dorsal fin and narrow, pointed flippers with a distinctive bulge on the leading edge. Females reach 4.5–5 m and 1,200 kg, and males 6 m and 2,200 kg. Its name comes from a skull that resembles the orca's (Wikipedia, general species account).

It is highly sociable and forms pods of up to 50, sometimes together with other dolphin species such as the common bottlenose dolphin. It typically eats squid and fish but has been known to eat other dolphins. It is a deep diver, with a maximum known depth of 927.5 m, and a fast swimmer at around 30 km/h. Gestation takes about 15 months. It is threatened by fishing operations, as it can become entangled in fishing gear (Wikipedia, general species account).
