Hermaphrodite worms?

Question

Why is it beneficial for the worm to be a hermaphrodite if it reproduces sexually?

Answer 1

Although hermaphroditic (containing both male and female reproductive organs), worms do need to reproduce sexually with a partner.  When worms copulate, both of the worms become fertilized and bear young.

Answer 2

It's not a herm, it can chose to be male or female depending on what is needed at the time like oysters.

if there are a lot of male worms, some can turn female to reproduce, and vice verse.
