I think this is the prettiest little crab I've ever seen.
This little crab's body is about as big as my thumbnail and it's a digger. It was in a tank where you could see the tunnels it dug in the sand against the glass, like an ant farm.
And this poor little thing, I realized while shooting it that it was missing a lot of its legs. The glass of the tank was sweaty and I was taking pictures with the lens in the clear spots of the glass but I like the hazy look around the edges.
