Hermaphrodite Sea Slug Mates With Throwaway Penis
“A bizarre, hermaphrodite sea slug may give new meaning to the word “quickie.” The nudibranch uses a disposable penis to have sex more frequently, according to a new study.
The animal, described today (Feb. 12) in the journal Biology Letters, is the first discovered to use an easily regenerated, disposable penis.
Nudibranches are simultaneous hermaphrodites, meaning that they have penises that they use to fertilize others as well as female sex organs. But exactly how their sex worked remained a mystery.”
