Spiders

![image] ()Spiders are predators (carnivores), sometimes even cannibals. The prize winner is an insect. Almost all types of spiders, with the exception of about 150 species of the Uloboridae and Holarchaeidae tribes, and the suborder of Mesothelae, are able to inject through their tusks to their enemies or prey. However, of the thousands of species that exist, only about 200 species that can be classified as humans.

Not all spiders make a net for prey, but all are capable of producing silk threads - the striking but powerful strands of protein fibers - from glands (called spinnerets) placed in body parts.
