I thought that for a second initially, but then took a closer look. The shorter two antennae ones are different than the long thin legs, they are sort of feathery and thicker. Also, I have come across four of these creatures so far and they are all identical, so there is no way that all four of these different serpent stars happen to have the same mishap and end up with a pair of shorter legs.

Somewhere in the back of my brain I think I remember reading about a reef pest that fit this description, but now I cannot find anything on it. I keep hoping someone will read this and and know exactly what I am talking about.
