Echinodermata literally means spiny skin, and the group includes starfish, sea urchins and sea cumcumbers. Other invertebrates do have spiny skin, though, including many arthropods.

Yes, it is an invertebrate because i am doing a project on it and we are studying invertebrates. (and I'm only 12!)
No, while crabs are indeed invertebrates thy have a carapace not a skin.
they have no backbone this is true to all invertebrates
Because the name is spiny which makes them spiny
