Orcas have a long life span. The average life expectancy for males is 29.2 years, with some living well into their 50s. Females live into their 80s. Births are, on average, one calf every ten years, with newborns reaching lengths of 2.5 meters. Each killer whale pod communicates using their own unique dialogue of whistles, clicks and shrieks.
Orcas also use echolocation, a type of sonar, to locate their prey.
The Orca also relies on its fine eyesight with a visual ability likened to that of a cat. There are three genetically distinct types of Orca whales, each with a specialized feeding adaptation. These groups are classified as 'resident', ' transient' and 'offshore' Orca whales. A large male can eat up to 200 pounds of salmon in a single day. They can be seen in this area from May through to October, at which time they move into other coastal waters.
