[Coral-List] Can Blue Sea Stars Eat Giant Clams?

As an interesting, and probably not true, anecdote:

About 45 years ago or so I was very interested in salt water aquaria. 
 At that time, no one could figure out how to keep Linckia alive.  As I 
recall it, an article appeared in one of the prominent publications of 
the time, that a frustrated aquarist, in total disgust, threw his peanut 
butter sandwich into his aquarium.

Of course, Linckia immediately jumped on it and consumed the peanut butter.

Well, it's a good story anyway.
