The thief of snails nest

Some time ago, I hunted photos on the coast in Aceh Besar, Aceh. In the hunt, I saw some snail shells in the bushes. At first I suspect this is a snail or mollusca or melanoides or vivipara. But, I wrong. Molluscs in scientific language mean soft. But, the snails I found were like crabs with mollusca shells.

I'm assuming this is a type of crab shell thief. But it is possible if the crabs take advantage of the empty shells of a dead snail.

I am curious about this marine biota. I then reset some references about the types of sea shells, snails, and also shrimp on the internet pages. After spending a few hours, I finally found an animal identical to the theft of the nest. The name of this marine biota was decapod crustacean.

She went into a family of shrimp that had a rolled stomach. Stomach with a shape like this is useful to grip the snail shell.

I am not a biologist. So I put a more focused website link about this animal. Check here or here.[]
