HOW CAN YOU TELL THE DIFFERENCE BETWEEN A MALE AND FEMALE STARFISH?

BIOLOGY RESEARCH PAPER...
Rebeca:

It's almost impossible to determine the sex of a seastar without dissecting it. The only way to tell from the outside if a seastar is a male or female is to catch it spawning, if it sheds eggs, it's a female; if it sheds sperm, it's a male. Seastars, and all the other echinoderms, lack any external features that identify them as male or female. In other words, they are not sexually dimorphic. Males and females look the same.
