Orca, sometimes known as ‘killer whales’, are unmistakable with their black and white markings. Although we do have a small group of orca who live in British waters, you would be lucky to see them!

About

Orcas are incredibly clever animals, roaming huge distances in search of prey in tight family groups that share their own special language. Their black and white markings are unmistakable, making them very easy to spot. However, the UK’s resident orca community consists of just eight individuals, four males and four females, which means seeing them is rare! Known as the ‘west coast community’ this resident group of orcas arrive in Northern Scotland in early summer to feast on fish. Unfortunately, no calf has been born to this group in over 20 years.

How to identify

The black and white pattern and enormous dorsal fin make the orca unmistakable. Males are larger than females and have much taller dorsal fins, sometimes up to 1.8 metres tall. A female's fin is around half this height and curves backwards.

Did you know?

Orcas, or Killer Whales, are actually dolphins! They are the largest member of the dolphin family and their name originated as "whale killer" as they are known to work together to kill whales much larger than themselves.
