Southern resident society is divided into a number of family lineages, the members of which share a recent maternal ancestor. The lineages with the most genetic links to each other come together to form the matrilineal families known as J-Pod, K-Pod and L-Pod.

How are orca pods named?
The numbering system for orcas was created in the 1970s by Canadian researcher Michael Bigg to determine the size of the whale population along the Pacific Coast. The letter is the name of the pod; the numbers were originally based on the order in which the whales in the pod swam by his boat.
How many ecotypes of orcas are there?
There are ten orca ecotypes around the world. Scientists separated orca populations into these ten ecotypes based on body size, coloration, habitat range, vocalizations, diet, and social structure. Currently, all the orcas that populate the oceans are scientifically named Orcinus orca.
