About the Orca

Orcas (Orcinus orca) are apex predators known for their distinctive black-and-white colouring and highly structured social groups. They are incredibly intelligent and versatile hunters. They can use complex strategies to catch a wide range of prey, from fish and squid to seals, seabirds, and even whales.

Orcas live in matriarchal pods, led by older females whose knowledge of hunting grounds and migration routes guides the group’s success. These pods exhibit strong family bonds, often remaining together for life. Known as “killer whales,” Orcas are not true whales but the largest members of the dolphin family. They can reach up to 9 metres (30 feet) in length and weigh up to 6 tonnes (13,000 pounds). Their communication involves sophisticated clicks, whistles, and calls unique to each pod. 

They are commonly seen in coastal waters but also inhabit deeper oceanic environments.

Orcas face pollution, depletion of their prey species due to overfishing, and captivity in marine parks. They are also affected by changes in sea temperature and ice cover due to climate change.

Changes in sea ice and temperatures can influence the range and distribution of their prey species, affecting their traditional hunting grounds.
