What body segments do arthropods have?
What body segments do arthropods have?
Arthropod segments have also fused together into functional units called tagma. This process of segment fusion, or tagmosis, usually results in an arthropod body that consists of three major sections, a head, thorax, and abdomen. Sometimes the head and thorax are fused together into a cephalothorax.
What makes arthropods unique?
The distinguishing feature of arthropods is the presence of a jointed skeletal covering composed of chitin (a complex sugar) bound to protein. The body is usually segmented, and the segments bear paired jointed appendages, from which the name arthropod (“jointed feet”) is derived.
Do all arthropods have a segmented body?

What are the major characteristics of arthropods?
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.
Are there any arthropods that are internally segmented?
At some point in their lives, all arthropods have bodies that are internally and externally segmented. These segments piggyback on one another, like a series of cars in a train.
What kind of body plan does an arthropod have?
Arthropods have a number of distinctive features in their body plan: Three tissue layers formed in embryo, like most animals. True coelom. Segmented body with specialized and fused segments.
Which is the largest group of arthropods in the world?
