Heads

1. They have segmented bodies and show various patterns of segment fusion (tagmosis) to form integrated units (heads, abdomens, and so on).

Worms

1. Their segmented bodies and coelom have given them evolutionary advantages over other worms.

Annelids

1. All annelids (�little rings�) have segmented bodies.

External Skeletons

1. Just why prehistoric arthropods -- creatures with external skeletons and segmented bodies -- grew so large is unclear.

Six Legs

1. Like true insects, adult springtails have hard, segmented bodies and six legs, but they display some unique biological traits that set them apart.

Crustaceans

1. With their segmented bodies and hard outer shells, the insects descend from marine creatures akin to the crustaceans.
2. Crustaceans have jointed appendages, meaning their legs can bend, and they have segmented bodies.

Jointed Appendages

1. Both belong to the phylum Arthropoda in the animal kingdom, which consists of animals with segmented bodies and jointed appendages.
2. Arthropods are characterized by a stiff exoskeleton, segmented bodies, and jointed appendages.

Exoskeleton

1. Insects possess segmented bodies supported by an exoskeleton, a hard outer covering made mostly of chitin.
2. They have segmented bodies supported by a hard external skeleton (or exoskeleton).

Arthropods

1. Arthropods are a group of animals with exoskeletons made of chitin, segmented bodies and jointed limbs.
2. Historically, the closest evolutionary relatives of arthropods were considered to be annelid worms, as both groups have segmented bodies.

Jointed Legs

1. Arthropoda: The largest single animal phylum, consisting of organisms with segmented bodies, jointed legs or wings, and exoskeletons.

Segmented Bodies

1. ARTHROPODS: INSECTS, ARACHNIDS, AND CRUSTACEANS. Arthropods are animals with exoskeletons (external skeletons), segmented bodies, and jointed legs.
2. Arthropods are animals with jointed legs and segmented bodies, such as insects, spiders, centipedes, and crustaceans.
