How are orca whales identified?
The saddle patch right behind the dorsal fin is like a fingerprint. No two orcas have the same patch. Also, height and shape of dorsal fin can be useful as well as notches, scratches and if the fin leans to one side or the other.
The SRKW (Southern Resident Killer Whales) are a matrilineal animal. Both sons and daughters stay with their mother during their lifetime. Like humans, females live longer than the males. Females have been estimated at 90 years old. Males have been estimated at about 60 years. And like humans, the SRKW come into sexual maturity in their teens.
How do these our resident orca differ from other orca in the same waters? The SRKW share the same language, and each individual pod also uses its own dialect. They are territorial and their territory spreads from northern California to northern Vancouver Island.
