I’m not sure but assume these marks were caused by a Sea Lion fighting back……..and yes it was probably the last thing it ever did….cause their on the menu!
UPDATE : May 1/19 – Here is my latest theory……These markings may be from the adults?
When we all were children our mother or father sometimes scolded and disciplined us.I think these marks are from the teeth of the mother and father scolding the calf. Like getting your rear paddled.
I’ve asked the experts but they do not seem to know,but they do say these marks are common on Orcas.
