“tarantula”的意思、由来-百科全书

tarantula

spider

any of numerous hairy and generally large spiders found in the southwestern United States, Mexico, and tropical America. Many tarantulas make burrows in soil and feed mainly at night on insects and occasionally small frogs, toads, and mice. In the southwestern United States, species of the genus Aphonopelma can attain a body length of up to 5 cm (almost 2 inches) and a leg span of up to 12.5 cm (almost 5 inches). The spiders, dark in colour and sluggish in movement, have a hairy body and hairy legs. Theraphosids are harmless to humans, although they can inflict painful bites if provoked. They are often kept as pets.

The most common North American tarantula is Eurypelma californicum, which is found in California, Texas, and Arizona. A 30-year life span has been recorded for one individual of this species. Certain South American tarantulas (genus Theraphosa) called bird-eating spiders have a body length up to 7.5 cm (almost 3 inches) and reportedly capture and eat small avian prey.

The name tarantula was originally given to the wolf spider, Lycosa tarentula, of southern Europe and was derived from the town of Taranto, Italy. The bite of L. tarentula was once thought to cause a disease known as tarantism, in which the victim wept and skipped about before going into a wild dance (see tarantella). It has been shown, however, that the bite of L. tarentula is not dangerous to humans and that no ill effects can be attributed to it. The body of L. tarentula is about 2.5 cm (1 inch) long. Like other wolf spiders, it spins no web but catches its prey by pursuit.

Other spiders belonging to the same family as the New World tarantulas are the monkey spiders of Africa and the bird-eating spiders of Australia and New Guinea. trap-door spiders and the dangerous funnel-web spider of Australia are also related to the theraphosids as members of the primitive suborder Orthognatha.
