What are sequential hermaphrodites?

• Sequential hermaphroditism is a type of hermaphroditism that occurs in many fish, certain plants as well as gastropods. This occurs when an organism changes its sex at some point of time in their life. The prefix "sequential" suggests that this change goes about in a coordinated fashion with a series of processes in-between.
