All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae.

What are the 5 characteristics of arthropods?

  • They possess an exoskeleton.
  • They have jointed appendages.
  • Their body is segmented.

Which type of arthropod is a lobster?

Crabs belong to the subphylum Crustacean, the largest group of marine arthropods, which also includes lobster, shrimp, and krill, a shrimp-like crustacean.

Which of the following characteristics is shared by all arthropods?

All arthropods share these characteristics:

  • Segmented bodies.
  • Jointed appendages such as mouthparts and antennae.
  • Bilateral symmetry.
  • Dorsal blood vessel.
  • Ventral nerve cord.

What do all crustaceans species have in common?

Their jointed, biramous appendages may present in all three body regions. Unlike insects, adult crustaceans have two pairs of antennae. Their chitinous cuticle is often elaborated as a shield-like carapace, and their abdomen typically has more than 11 segments.
