Based on my research spider is a kind of insects that belong to different animal groups. Spiders are arachnids – technically Class Arachnida, which includes ticks, mites, scorpions and harvestmen (daddy-long-legs). The most obvious way to distinguish insects from spiders is to count their legs. Insects have six legs, while arachnids have eight. Spiders have a hard outer body called an exoskeleton. They have two main body parts, the cephalothorax and the abdomen, plus eight jointed legs. Most spiders have eight eyes. Spiders have jaws (chelicerae) with fangs. Near their mouth, they have a set of leg-like appendages called pedipalps, which are used for handling prey. Spiders feed on liquids and cannot take in solid food. They mix digestive fluid with the prey’s tissue and suck up the partially digested nutrients. While some spiders tear apart their prey, others leave the corpse almost intact, appearing to feed more like a suave vampire than a dismembering werewolf.
Anyway, I found the spider in our wall. It climbs on the ceiling and right away I was took a photo.
