Cownose visit for Thanksgiving

A crowd was gathering on our beach this morning - what's all the fuss?

A school of cownose rays ranging from 26 - 36 pounds was visiting for Thanksgiving!  There were several large schools with hundreds swimming by. Generally considered docile unless you mess with them; their tail can whip you with a barb that cuts you.

Maybe they are searching for a meal of oysters and clams as they were swimming north and at this time of year we expect them to migrate south.
Hummmmm .... they are a  'near threatened' species of eagle ray.

Can you see the edges of their pectoral fins sticking out of the water? The males try to grasp these to mate. Seems a bit late in the year, but are these cownose mating? They also sometimes splash and can jump clear out of the water too.
