Regularly in the darker sides of the sea their vision gets feeble and make its hard to see their prey, for this situation they utilize their sound receptors to explore. Orcas have all around created hearing. Ongoing examinations have shown that orcas can hear up to 100kHz. The lower jaw of the executioner whale additionally goes about as a sound receptor (Diagram C).

Under the orcas skin is a thick layer of lard which ensures the measure of warmth misfortune. Executioner whales have an elevated ability to burn calories, which additionally makes a great deal of body heat. The orcas circulatory framework help with keeping the internal heat level set up.

Research shows that executioner whales are equipped for tearing seals of ice. Whales chase in a gathering called â€Å"pods†. There are two sorts of cases private and transient.
