Did you know that eels go through a larval stage? I didn't until I came across this video last night.
Apparently this is a ribbon eel, in the moray family, and its larval stage consists of it being an approx. 3" wide, 2-foot long TRANSPARENT body with a little head stuck on the end. And then it will go away, and become a real eel. How freaky is that?

LOOK AT ITS LITTLE FACE!
Also according to the write-up, you seldom get footage of eels in this stage, because since they are transparent, it's hard for divers to find them.
It's just mesmerizing to watch.
