Spiders are predators feed primarily on insects. Depending on the species, some spiders rely on their webs to capture their prey, while others actively hunt their prey.

Medical Importance

Spider bites usually only occur with great provocation such as squeezing or handling. Many spiders cannot penetrate the skin and the bite of those that can, usually results in no more than slight swelling. The primary exceptions are black widow and recluse spiders.
