The characteristics of arthropods include an exoskeleton, well-developed sense organs, jointed appendages, tagmata body regions, a ventral nervous system and bilateral symmetry. Scientists believe that the ancestors of the arthropods were similar to that of a centipede and over millions of years the various segments fused together and formed new parts.Continue Reading
The anthropod's exoskeleton is made out of chitin and it sheds throughout the growth process.
Well-developed sense organs
These well-developed sense organs allow the arthropod to find its food and to get a sense of its environment. It also has well-developed nerve cords and mesodermal.
The jointed appendages, such as the antennae and the legs, give arthropods a unique look. All of these jointed appendages are connected to a body segment and move together with it.
Tagmata body regions
The tagmata body regions is one of the ways that arthropods are classified because scientists look at the way that the tagmata regions are arranged. There are different arrangements of the body regions, which include the head, the trunk, the abdomen, the thorax and the cephalothorax.
Ventral nervous system
Having bilateral symmetry means that the arthropod mirrors each side of its body and is identical on the right and left sides.
Most arthropods move through their segmental appendages. Their exoskeleton and muscles, which are connected to the inside of the skeleton, act together as a lever system, according to Encyclopedia Brittanica. The exoskeleton provides a large surface area for muscle attachment, supports movement and provides protection from the environment.Full Answer >
Vertebrates are characterized by the presence of a vertebra or backbone; a skull; skeletal bones that form an endoskeleton; a bilaterally symmetrical structure; and two pairs of appendages, such as fins, limbs or wings. Vertebrates' organ systems are more developed than those of invertebrates, and their nervous systems are more complex.Full Answer >
Millipedes are arthropods of the class Diplopoda, meaning double foot. Millipedes possess elongated, segmented bodies with two leg pairs per segment. These arthropods are detritivores that feed on decomposing organic material.Full Answer >
The common characteristics of arthropods are they are invertebrates, which means they lack backbones. In fact, they lack bones of any kind but possess a protective exoskeleton, which they molt in order to grow and repair themselves. They also have segmented bodies.Full Answer >
