What is the meaning of arthropods?
Definition of arthropod
: any of a phylum (Arthropoda) of invertebrate animals (such as insects, arachnids, and crustaceans) that have a segmented body and jointed appendages, a usually chitinous exoskeleton molted at intervals, and a dorsal anterior brain connected to a ventral chain of ganglia.
Which are the three main parts of the arthropods?
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.

The important characteristics of arthropoda include:
- They possess an exoskeleton.
- They have jointed appendages.
- Their body is segmented.
- They are bilaterally symmetrical.

Why is it called arthropod?
They are called arthropods because they have articulated legs in the adult state (arthropod means “articulated foot”). And, like other arthropods, the species that belong to the insect class have an exoskeleton, or external skeleton.

What makes arthropods so successful?
The incredible diversity and success of the arthropods is because of their very adaptable body plan. The evolution of many types of appendages—antennae, claws, wings, and mouthparts— allowed arthropods to occupy nearly every niche and habitat on earth.

Why arthropods are the most successful group of animals?
Arthropods are the most biologically successful group of animals because they are the most diverse and live in a greater range of habitats than do the members of any other phylum of animals.
Which characteristic is unique to arthropods?
The distinguishing feature of arthropods is the presence of a jointed skeletal covering composed of chitin (a complex sugar) bound to protein. This nonliving exoskeleton is secreted by the underlying epidermis (which corresponds to the skin of other animals).
