Spider vs. Centipede: What's the Difference?
"A spider is an eight-legged arachnid, usually spinning webs, while a centipede is a multi-legged myriapod with one pair of legs per body segment."
Spiders and centipedes are both arthropods, but they belong to different classes within the animal kingdom. A spider is a member of the class Arachnida and typically has eight legs, two body segments, and can produce silk. In contrast, a centipede belongs to the class Chilopoda and has a more elongated body with one pair of legs per body segment, amounting to a variable number of legs depending on the species.
While spiders are well-known for their ability to spin webs using silk produced by their spinnerets, centipedes do not have the ability to produce silk and do not create webs. Instead, centipedes are swift movers and are known for their speed and agility. Spiders generally consume a diet of insects and other small creatures that they trap in their webs, while centipedes are carnivorous, preying on a variety of smaller animals, using their venomous claws located just behind the head to paralyze their prey.
The appearance and anatomy of spiders and centipedes are quite distinct. Spiders have two main body parts: the cephalothorax and the abdomen. The cephalothorax bears the legs, eyes, and mouthparts. Centipedes have a segmented body, and each segment bears one pair of legs. The number of segments, and thereby the number of legs, varies widely among different centipede species.
The habitats of spiders and centipedes can overlap, as both can be found in a variety of environments ranging from forests to deserts. However, spiders are more likely to be found suspended in webs or hiding in secluded locations, while centipedes are more ground-oriented and may be found under rocks, leaf litter, or within soil. Both are predominantly nocturnal, preferring to hunt or be active during the night.

Any one of numerous species of arachnids comprising the order Araneina. Spiders have the mandibles converted into poison fangs, or falcers. The abdomen is large and not segmented, with two or three pairs of spinnerets near the end, by means of which they spin threads of silk to form cocoons, or nests, to protect their eggs and young. Many species spin also complex webs to entrap the insects upon which they prey. The eyes are usually eight in number (rarely six), and are situated on the back of the cephalothorax. See Illust. under Araneina.
