Aranha-golias-comedora-de-pássaro (Theraphosa blondi) is the Goliath Birdeater, an arachnid belonging to the tarantula group, and is considered to be the second largest spider (by leg-span) in the world. The spider was named by explorers from the Victorian era, who witnessed one eating a hummingbird.It is native to the rain forest regions of northern South America. These spiders can have a leg span of up to 12 inch and can weigh over 6 ounces. Females always mate, but eventually kill their mates. Females mature in 3 to 4 years and have an average life span of 15 to 25 years. Males die soon after maturity and have a lifespan of three to six years. Colors range from dark to light brown with faint markings on the legs. Aranha-golias-comedora-de-pássaro have hair on their bodies, abdomens, and legs. The female lays anywhere from 100 to 200 eggs, which hatch into spider lings within two months. They carry venom in their fangs and does not normally eat birds. As with other species of spider (specifically tarantula), their diet consists primarily of insects and other invertebrates. However, because of its naturally large size, it is not uncommon for this species to kill and consume a variety of vertebrates. In the wild, larger species of Aranha-golias-comedora-de-pássaro have been seen feeding on rodents, lizards, bats and even deadly venomous snakes.
