Arachnid are animals that have an exoskeleton, a two-part segmented body, and 8 jointed legs; they do not have a backbone. The body is divided into the prosoma and the abdomen. The prosoma anchors the chelicerae (pincers), pedipalps (mouth parts) and four pairs of legs.
Arachnid are aggressive predators. They are cold-blooded; their body temperature depends on the temperature of their environment. Arachnids breathe air through book-lungs, gill-like structures.
