So I am curious. You specify two pods of Orcas; how do you know if they are who they are, etc.? Who gives them their distinct pod names?
Let me see if I remember enough of what the biologist shared
Washington State Fish and Wildlife names pods in this state. Fish and Wildlife in California is also involved as the T in T137 means transient. In this case T137 calls California their home. Down there, California F&W calls them something else.
Orcas are matriarchal. So T137 is also the name of the matriarch of that pod. Pods can be ephemeral. They can split and rejoin. By and large the sons of a matriarch will stick with her for years. The daughters will go their own way after a year or two.
Sons are named by sticking on a letter. Daughters with numbers. So the sons of T137 are T137a, T137b and so on. The first daughter of T137a would be T137a1
