They can spin webs however, which they use to line their burrows. They overpower their prey with sheer force and inject it with venom. The venom is a combination of a paralyzing agent and digestive secretions. The victim is quickly immobilized. The digestive juices liquify the contents of the prey which is sucked out by the spider.
All spiders have venom glands.
Most tarantula bites are not generally harmful to man unless someone happens to be allergic to the venom. The male of the species is only sexually mature for the last few months of his life. Males generally live 9-10 years, but females live as long as twenty years. The female lays eggs in a sack woven from web silk which is carried attached to the abdomen until they hatch. The sack may contain 300-1000 eggs which hatch in sixty to ninety days.
