I WONDER - Why Are Spiders Not Insects?

The video explains the five key characteristics of insects: an exoskeleton, a body divided into three parts (head, thorax, abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. It highlights how these features help insects survive and interact with their environment. The video also distinguishes insects from arachnids, noting that spiders lack some of these characteristics.
