#salpidae

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.

透明なのもびっくりですが、魚じゃないというところがさらにびっくりですね^^;

A salp is an animal, it is a planktonic tunicate ( a marine invertebrate) in the family Salpidae.

I think they are really neat!
