Centipedes have too many legs! There bodies are not divided up into a
head, thorax and abdomen
Although they are sometimes grouped into the category of insects; centipedes are arthropods.
Crabs are crustaceans
They have an exoskeleton, however they have more than 6 legs and don’t have antenna
The cockroach had exactly six legs Its body is divided into 3 parts: head
