At a glance it looks like a snail, but unlike a snail it scurries around quickly.
How the Pagurus filholi lives
It spends its entire life in water. Before mating, a male grasps a female’s shell and carries it around. When other males challenge it for the female, the male flees or fights. Males also grasp and shake females vigorously; the reason is still unknown.
