Convict Fish

Pacificklaus

The convict fish has a highly unusual social organization: its adults seem to not leave the burrows they construct, and share with the juveniles. The juveniles forage for plankton in schools, and regurgitate some of their food into the mouth of the adult. A division of labor between generations, in a fish! Fascinating.

I wrote a blog post about this fish, featuring a video of the adult.

Moalboal, Cebu, Philippines. The fish in the pictures are juveniles.
