Spiders are predators carnivores, sometimes even cannibals. Its main prey is insects. Almost all types of spiders, with the exception of about 150 species of the Uloboridae and Holarchaeidae tribes, and the Mesothelae subordo, are able to inject through a pair of fangs to their enemies or prey. Spider weavers eg members of the Araneidae tribe make silk webs more or less round in the air, between leaves and twigs, and others. This net is sticky, to catch the flying insects that became its prey. Once the insect is caught in the net, the spider immediately approaches and jabs its fangs at the prey to immobilize and simultaneously transmit the digestive enzymes into the body of its prey. Some spider weavers have the ability to wrap the body of its prey with the coils of silk threads. This ability is especially useful if the prey has a dangerous self-defense device, such as a bee that has a sting; or if the spider wants to save its prey for some time while waiting for the preferred moment to enjoy it later.
