sea urchin
A (street) urchin is a child who lives on the street, surviving by engaging in petty crimes. A (sea) urchin is a spiny creature (exoskeleton), with a soft interior. I welcome improvements to this answer.
No they are considered a crustacean.
There are two common definitions of urchins. An urchin may be a sea urchin, a small prickly animal or to a street urchin or homeless child living on the street.
Sure. They belong to class Echinoidea.
I think a sea anenome and a sea urchin can live together because i have a little aquarium and there is a sea urchin and and a sea anenome (if that's how you spell it) living in there and they were perfectly fine. BUT if you have a sea urchin do not have any crabs in there, because my sea urchin killed one, and almost killed another one by taking its claw off. :(
Yes they are. It's kind of creepy.
