CRUSTACEA

Crabs, Lobsters, Crayfish, ShrimpAs a crab, Dear Potential Date…I have two pairs of antennae, and a pair of mandibles to cut food with to feed you when you’re hungry! I also have two compound eyes so that I can see you very well while we go on our first date. Also, my exoskeleton is unbreakable so I can protect you if anything ever starts to threaten your existence.
