Is My Arrow Crab a Turbo Snail Eater?

[See Gee Sea]

Hi all - I noticed this last night. The Arrow crab had a turbo snail on his right claw. I can't tell if he was saving it for later or the snail was just out for a ride. Do they eat snails? I know they have been known to eat small shrimp and fish but didn't see anything about other smaller inverts. He is very well fed.

Arrow crabs can and will eat snails.
They also go after bristle worms which can be considered good clean up crew as well..

Well, I just witnessed my emerald crab that I named crabzilla just tore a claw off of the arrow crab - which the LFS said to sump anyway given his taste in escargot. I learned that they've also been known to eat coral too.
