On this beautiful night I will make a post about animals. Spiders are predatory animals (carnivores). The main prey of spiders is insects. Almost all types of spiders, with very dangerous premises around 150 species of the Uloboridae and Holarchaeidae, are capable of injecting through a pair of fangs to an enemy or a type of prey. However, of the many species that exist, only about 150 species that bite can harm people.
