a starfish
To my knowledge there is not a specialty name for a male Clown fish.
The only term I have heard and can find is "male fish."
A star fish
As a star fish he technically has no sex (as in male/female)
It is called a Ray.
sunflower starfish
Dorsal
It is called "milt".
The average star fish can be called star shaped or a pentagon.
Males are called Spikes and females are called Fins.
Male and female fish have not been designated like other animals are, into things like cows and bulls, so they are simply called male and female.
I would assume they are called cocks, as in aquaculture a female fish is refered to as a hen. Actually a male fish is call a Buck.. Female=Hen.. This does not follow normal nomenclature. IE: Buck/Doe Cock/ Hen
