Grey seals need more depth in them!
Harems
Males form harems with multiple females in them.
Then sometimes some other males attempt to claim the harem for themselves in bloody fights. This behavior should also be observed in HnH (grey seals sometimes fight each other) I think.
Pups
During late autumn or winter even, there should be smaller (white) cute pups, in groups with 1 male, multiple females (1 pup at most for each female).
Also in general they should be more common on the shore than water, during autumn-winter especially.
In general all animals actually need improvement. There should be season specific behavior, season specific differences in look etc. Currently they are all just quite dumb things, standing around, same every season, little things like these would really add depth and flavor.
