PItity for the poor clownfish. This brightly coloured creature, made well-known within the 2003 animated movie The world of Nemo, is now diminished to the standing of a device within the debate on intercourse and gender id.

Which implies that if all clownfish begin out as males, some change intercourse if the college runs out of females.
