im doing some homework and i need to know if this is right:

"The oyster is usually ambisexual; it begins life as a male, then becomes a female, then changes back to being a male, then back to being female. It may go back and forth many times."

Protandric is the word your`e looking for. They are male for the first year and female for the next two or three.
