i found the same thing with surf species like bat rays, leopard sharks and shovel nose guitarfish. even though everything i could dig up said nothing about them being gender specific when schooling, i can show you a dozen pics of males from north SD and another dozen that came from south county. seemed to be like that up until July. now they are all mixed and not really in the huge schools they were before.
went to santa monica in the same time period and it was females there. i don't know where the males were hanging out up that way.
