Orcas, aka killer whales, are the largest of the ocean dolphins. These large, predatory marine mammals were first captured from the wild and displayed in public exhibitions in the early1960s; they quickly became popular attractions due to their capacity for training, and striking size and appearance. Presently there are around 45 orcas in captivity worldwide, most of which are now captive-born. Orcas are extremely intelligent, social animals with a highly evolved brain. Neurological imaging studies (MRI) show that orcas possess an extensive para-limbic system suggestive of an elaborate emotional life. In the wild orcas live in close family groups (or pods) and different groups are believed to have developed their own ‘language’ and ‘culture’. While much of the orcas lifestyle is a mystery they have been known to swim up to 160 kms in one day at speeds of up to 50 kms an hour, and typically dive 30-60 kms below the surface. Orcas create 'sound pictures’ of their habitat using echolocation, and their diet consists of live: fish, seal, sea lion, seabirds, squid and other marine animals including whales.
