Question

do cocoroch have backbone​

Answer 1

(you mean cockroach right)

A cockroach has six legs, three body segments, and no bones. It has an exoskeleton in place of a skeleton. The endoskeleton is hard and shell-like and covers its body.

Cockroaches are arthropods, and just like all arthropods, they don't have a spine, making them invertebrates. In fact, cockroaches don't have any other bones either. But in order for a cockroach's muscles to properly operate their legs, wings and other moving parts, they have to be attached to something rigid.
