the goliath birdeater tarantula

Theraphosa blondi is native to the rainforest of norther SouthAmerica.Wild Goliath Birdeaters are a deep burrowing species,found in marshy or swampy areas,usually living in burrows that they have dug or wich have been abandoned by other burrowing creatures.Females mate a lot and sometimes end up eating off their mates.Females mature in 3 to 4 years and their lifespan has an average of 15 to 25 years.Soon males die after maturity and have a lifespan of 3 to 6 years.colors on the legs range from dark to light brown with faint markings on them.goliaths have hair on their bodies,abdomens,and legs.The female lays from 100 to 200 eggs,wich hatch into spiderlings within 2 months.These spiders have a legspan up to 30cm (12 inch.)and can weigh over 170g (6 ounces).These spiders are onr of the few species that lack tibial spurs,wich located on the first pair on the legs of an adult male,wich serve to keep the males fangs immobolized during mating,so that the female doesn't eat him.Goliath birdeaters are quite harmless to humans,as are most species of tarantulas.Like all tarantulas,they have fangs long enough to break the human skin(1.9-3.8cm or 0.75-1.5 inch.).They carry venom in their fangs and are known to bite when they feel threatened,but their venom is relatively harmless and the effects are comparable to those of a wasp sting.also when threatened they rub their abdomen with their hind legs and shoot hairs into the air that are severe irritant to the skin mucas membranes.they have urticatinghairs that can even be harmful to humans,and are considered by most urticatin hair of all.tarantulas generally bite humans only in their self-defense,and their bites do not always result in envenomation (also a dry bite).These spiders have poor eyesight and mainly relies on vibrations in the ground so that it can sense from its burrow.also despite its name the goliath birdeater doesn't normally eat birds.as with other species of spiders (specifically tarantulas),their diet consists primarily of insects and other invertebrates.However,because of it's naturally large size it isn't uncommon for this species to kill and consume a variety of vertebrates.So in the wild,larger tarantula species have been sighted eating rodents, lizards,bats and even venomously/deadly snakes.While in captivity,Goliath bird eater's staple diet should consist of cockroaches.Spider-lings could be fed roaches or crickets that do not exceed the body length of one individual.DONT feed mice to the birdeater because its vitamins can be harmful to them
