ARTHROPOD Crustaceans Also, insects, arachnids, etc. Generally, invertebrates with jointed limbs and a hard external skeleton are called arthropods. See http://en.wikipedia.org/wiki/Arthropod
Invertebrates having jointed limbs and a segmented body with an exoskeleton made of chitin.
Jointed limbs are an important development because they allow animals, including humans, to move. Without joints we would be comprised of an immobile skeleton.
Hornets with their jointed limbs and chitinous exoskeletons are most definitely arthropods, under Arthropoda's subphylum Hexapoda, along with all other insects.
They are vertebrates - they have a complete skeleton including spine, skull and limbs.
Yes, invertebrates do have limbs.
yes, because it has its skeleton on the outside (its shell)
Yes. Arthro = jointed, pod = limb or leg.
no. just simply no. ok
The appendicular skeleton is attached to the axial skeleton.
No, some such as worms have no limbs whereas insects have six and octopuses have eight.
A spider is none of the above, as it is not a vertebrate, i.e. an animal having a backbone. A spider is an invertebrate, specifically, an arachnid.
Mammals limbs look different from species to species. Limbs are prehensile or jointed appendages and include arms (from the shoulder down) and legs (from the hip down).
