False killer whale

What do false killer whales look like?

You’ll recognise these dolphins pretty easily because of their long, slender, black or dark grey bodies, a narrow pointed head with no beak and a prominent bulbous forehead, or ‘melon’. They have long, slim S-shaped flippers that make them look as though they have elbows and a tall, tapered dorsal fin. These dolphins will usually have a slightly paler neck and some individuals have a pale ‘W’ shape on their chest. They look similar to pygmy killer whales and melon-headed whales and are very difficult to tell apart. False killer whales are much bigger and their size and unique flippers mean you can tell them apart, but only if you know what you are looking for.

What’s life like for a false killer whale?

Family and friends are everything if you’re a false killer whale. They are highly social, forming strong, lasting bonds and friendships. These spirited dolphins tend to swim energetically in groups of 10 to 40 dolphins, jumping out of the water, performing flips and generally mucking about together. Sometimes they will join with other pods to form superpods of hundreds of individuals. Can you imagine what an awesome spectacle that is if you are lucky enough to witness it?

A false killer whale mum will nurse her baby for up to two years while she teaches her or him everything they need to know about being a dolphin.

What do they eat?

False killer whales mostly eat fish and squid but sometimes they go for other marine mammals, such as smaller dolphins or even humpback and sperm whales, although scientists aren’t sure if they eat them or just kill them to get rid of the competition for food. They eat bigger fish than many other dolphin species with an appetite for tuna and mahi-mahi and can consume up to five per cent of their own body weight every day.

Feeding isn’t a solitary pursuit. They will hunt together and share food around between pod members and have even been known to offer food to human divers and snorkelers.

Where do they live?

These remarkable dolphins are found in tropical to warm, temperate waters all over the world. Sadly, most of what we know about where they live and the routes they travel, comes from studying individuals who have stranded - in fact we don’t even really know if they migrate.

The populations seem to be pretty spread out, and are often found in deeper seas which means that we don’t know an awful lot about them. But there is one population, who live in shallower waters off Hawaii, that is well–studied, and a lot of what we do know comes from this group.
