Characteristics

Arthropods are the largest animal group on Earth. The most characteristic feature of arthropods is their external skeleton.

The articulated exoskeleton (external skeleton) is made up of hard, small plates that cover the body. Like a human skeleton, it supports and projects the body, but it is external. 

This makes arthropods invertebrates.

Arthropods have jointed legs. They also have antennae and eyes
