Characteristics of Arthropods
- A segmented body (Figure below) with a head, a thorax, and abdomen segments.
- Appendages on at least one segment. ...
- A nervous system.
- A hard exoskeleton made of chitin, which gives them physical protection and resistance to drying out.

What are the main features 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.
What is the external covering of an arthropod called?
Arthropods are covered with a tough, resilient integument or exoskeleton of chitin. Generally the exoskeleton will have thickened areas in which the chitin is reinforced or stiffened by materials such as minerals or hardened proteins.
Do arthropods have an external shell?
The external skeleton of arthropods is a highly efficient system for small animals. The exoskeleton provides a large surface area for the attachment of muscles and, in addition to functioning in support and movement, also provides protection from the external environment.
Which feature is not found in the arthropods?
> Thus, the correct answer is Parapodia which is not present in the Phylum-Arthropoda.
What are the characteristics of arthropods quizlet?
What are the four Characteristics that all Arthropods share? a segmented body with specialized parts, jointed limbs, an exoskeleton, and a well-developed nervous system.
What are 2 features that make arthropods so successful on land?
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.
What are the key features of arthropod cuticle?
The cuticle provides muscular support and acts as a protective shield as the insect develops, but it is not in itself cellular, so once established it cannot grow and offers little scope for maintenance, renewal or increase in size as the animal grows.
What are the Locomotory organs in phylum Arthropoda?
Muscles, appendages, and locomotion. Arthropods are unusual among invertebrates; they lack locomotory cilia, even as larvae. The problem that a rigid external covering imposes on movement has been solved by having the exoskeleton divided into plates over the body and through a series of cylinders around the appendages.
Do all arthropods have a hard outer covering?
All arthropods have a hard, outer covering called an exoskeleton. It covers, suports, and protects the internal body and provides places for muscles to attach. An insect's head has a pair of antennae, eyes, and a mouth.
Which feature is characteristic of both annelids and arthropods?
A distinguishing characteristic shared by annelids and arthropods is their body segmentation. At some point in development, segmented animals possess a body plan with repeating segments of identical or similar structures. Later in development, some segments may form more specialized structures.
Which feature is characteristic of arthropods and relates them to annelids?
All arthropods differ from their annelid ancestors in several important ways: they have a chitinous exoskeleton, jointed/segmented appendages, a well-developed head and mouthparts, striated muscles, and an open circulatory system with a dorsal heart.
What is the unique feature of Arthropoda?
A unique feature of animals in the arthropod phylum is the presence of a segmented body and fusion of sets of segments that give rise to functional body regions called tagma. Tagma may be in the form of a head, thorax, and abdomen, or a cephalothorax and abdomen, or a head and trunk.
What are the 4 inherited characteristics of arthropods?
They include insects, arachnids, myriapods, and crustaceans. They are generally characterized by the following features: (1) a hard chitinous exoskeleton, (2) segmentation, (3) multiple jointed (paired) appendages, and (4) an open circulatory system.
