yes
crabs are invertebrates
Crustacean
Noooooo! A crab is an arthropod! (invertabrate)
Crabs are in the crustacean category, jellyfish are members of the cnidaria. Sponge are porifera.
I am assuming you mean horseshoe crab, in which case they are invertebrates.
invertebrateA fiddler crab is invertebrate. It does not have a spine.
Animals without back bones are called Invertebrates.
The Spider Crab covers its back with various spines and tubercles, algae, and small invertebrates. It does this for self defense against predators.
Yes. It has a shell. Invertebrates have no backbone, vertebrates do. Invertebrates often have a hard external shell (like a mussel), or exoskeleton (like a crab), to protect them from predators.
Crab classification: Phylum - Arthropoda Subphylum - Crustacea Class - Malacostraca Order - Decapoda
It's an invertebrate. It has an exoskeleton, so it's supportive structures are on the outside.
Jellyfish, slug, snail, crab, octopus, all invertebrates have no bones.
