Uncharismatic Fact of the Day
For the salp, sex is less of an immutable part of their biology and more like a hot potato. In their aggregate stage, these invertebrates attach together in chains. When an female chain has been fertilized by a male chain, each member will give birth an asexual offspring called an oozooid, which can later release tens of thousands of young which will grow up to aggregate together again. In the meantime, after giving birth the original fertilized aggregate salp becomes male, and will seek out a female to mate with.
