While not in game, let me tell you about the pod structure of Orcas.
Orcas are one of the best examples of matriarchal. Eldest female leads her pod, orca pods have sisters, brothers, aunts, uncles, grandmothers, mothers, sons and daughters.
The matriarch is familiar with where to go for fishing in specific areas, knows when to divide her pod and what pod can mate with.
When it comes to mating, pods will form Superpods consisting of 2 and sometimes more pods. The entire pod will vocalize, if any opposite pods sound similar, then those members are off limits. Once mating is finished, the males go right back to their mothers (think of them as Johnny Bravos or mommas boys). Each pod has their own dialect ftr.
When a pod has gotten too large, the second eldest female will create a sub pod. A sub pod consists of a few members potentially the sub matriarchs children and there will be at least one male.
I can go on all day as I worked on tours where orcas were a recurring animal.
Family is everything for orcas, the females are always the brains, the males are always the muscle.
