Key Facts about Spiders: 

  • Spiders are not insects, but belong to a group called the arachnids. Spiders differ from insects as they have eight legs not six and six or eight eyes (two in insects).
  • Spiders are known for making silk webs to catch insects. They spin silk from a liquid made by special glands. They are found everywhere in the world, except for Antarctica.
  • Most spider species are carnivorous that capture and eat other insects. However, one species in Central America has been found to be mostly herbivorous. 
  • Spiders digest their food outside their bodies. After capturing its prey, a spider covers it with digestive juices. The juices break down prey’s body into liquid form that the spider sucks up.
  • Spiders are important pest controllers for a habitat, and they are food for other species too.
  • Spider webs are the extensions of the spider’s sensory system. Vibratory information from the web is crucial for spiders because they do not have ears. 
  • Spider silk is an amazing natural material with unique properties. It has inspired researchers to develop materials derived from spider silk with applications in tissue engineering and regenerative medicine.
  • Spiders shed their outer covering, multiple times before becoming adults.
