Some of the colors hermit crabs have is red, orange, and yellow. It's body has 8 legs plus 2 claws. The left claw is always larger than the right claw. The left claw secures the shell when the crab is tightly packed inside. If you try to pull a hermit crab out of it's shell you will tear it into pieces.
Hermit crabs tend to be nocturnal and they eat near sunrise or at dark.
They are also active during daytime in captivity. If a herit crab pinches you while you are holding it in your hand, that means it thinks it is going to fall. To get them to let go you must lay your hand in the bottom of a sink so the crab is not hanging, then run the whole crab under cool water. Click me to go home.
