Changing sex is more common than you might think.No kidding.
Many animals start out as one sex, and then change into the other part-way through their lives.You don't say.
There are also plenty of animals that are both male and female at the same time.Protandrous, I think, but no matter. As in protandrous dichogamous pseudohermaphroditism. OK, that's weird. Another one to add to the collection of Natural Wonders that disprove many religions' contentions about "Natural Law".
But a few go one step further. They start out as one sex, and then transform into hermaphrodites.
The peppermint shrimp is one of these rare beasts. It gets its name from the red stripes that run along its translucent body, which make it look like a peppermint stick or candy cane.
It first matures as a male, and sometimes turns into a hermaphrodite with both male and female sexual organs. This lifestyle, named by an extreme-pronunciation enthusiast, is called protandric simultaneous hermaphroditism.
