Are Jumping Spiders Poisonous?

Jumping spiders are large, scary arachnids, but they are not poisonous or harmful to humans, according to Colorado State University. Jumping spiders can grow to over an inch long, and their bodies are thick and stocky, which gives them a frightening appearance.

These spiders get their name from the male of the species. If the female approaches the male too quickly during mating, he will jump. They also leap onto their prey. Jumping spiders enjoy sunshine and prefer to do their hunting during the day, and they possess excellent eyesight. The jumping spider does not spin a web, but it can often be seen hanging from a line of silk that protects it from falling.
