Excerpt: The A30 matrilineal is the name given to the most commonly seen orca matriline in British Columbia . The matriline is currently made of 3 generations, with a total of 10 individuals.

In 2001 the family welcomed the arrival of Cedar (A75), Blinkhorn (A54)'s first offspring and in 2005 Clio ga...
