We found that perceived fear and disgust of spiders were triggered predominantly by enlarged chelicerae, enlarged abdomen, and the presence of body hair. Longer legs were associated with perceived fear as well; however, the presence of two eyes did not produce any statistical significance in terms of fear.

Centipedes, scorpions, and some insects such as wasps feed on spiders. Wasp species such as tarantula hawks (or spider wasps) and mud daubers paralyze the spider with its sting and lay an egg inside the spider's abdomen. Then, when the wasp larvae emerge, they eat the spiders from the inside out.
They do not have venom glands, fangs or any other mechanism for chemically subduing their food. Therefore, they do not have injectable toxins. Some have defensive secretions that might be toxic to small animals if ingested.
The wolf spider is one of the most intimidating spiders because of its hairy nature. It is often mistaken for the tarantula , but unlike the tarantula, it's venom is not dangerous to humans. The wolf spider is quite large, and they are usually brown and black with grey coatings.

Snails, spiders and octopi have something in common- they all have blue blood! We're not talking in the sense of royalty, these creatures literally have blue blood. So why is their blood blue and ours red? One of the purposes of blood is to carry oxygen around the body.
No spiders are known to feed directly on vertebrate blood, but Evarcha culicivora, a jumping spider (Salticidae) from East Africa, preys frequently on blood-carrying mosquitoes in the field (1). That blood is ingested is evident when viewing the spider feeding under a microscope.
