[12] The huntsman spiders found in southern parts of Florida are of the Heteropoda venatoria species and considered an invasive species transplanted from Asia. Huntsman spiders are renowned for the enormous size, with males able to achieve a leg span of between 10 and 12 inches.They are sometimes called giant crab spiders or wood spiders because they like to live in woody areas such as forests, sheds, and woodpiles The average huntsman spider species is about 1 inch (2.5 centimeters) long with a leg span of up to 5 inches (12.7 … They are able to travel extremely quickly, often using a springing jump while running, and walk on walls and even on ceilings.

Brown Huntsman (Heteropoda species) spiders are patterned in motley brown, white and black. They are mostly grey to brown, sometimes with banded legs. Huntsman spiders are members of the Sprassidae of which there are more than 1,000 species. A few species are native to colder climates, like the green huntsman spider (Micrommata virescens) which is native to Northern and Central Europe. However, the formal study of spider bites is fraught with complications, including unpredictable infections, dry bites, shock, nocebo effects, and even bite misdiagnosis by medical professionals and specimen misidentification by the general public. This sound can often be heard as a rhythmic ticking, somewhat like a quartz clock, which fades in and out and can be heard by human ears in a relatively quiet environment. Huntsman spiders are large, long-legged spiders. They tend to live under rocks, bark and similar shelters, but human encounters are commonly in sheds, garages and other infrequently-disturbed places. [14], As adults, huntsman spiders do not build webs, but hunt and forage for food: their diet consists primarily of insects and other invertebrates, and occasionally small skinks and geckos. In Australia a huntsman spider was seen dragging a dead mouse up the side of a fridge. However an investigation into spider bites in Australia, in which Huntmans featured prominently, did not show any serious consequences of being bitten. They are sometimes called giant crab spiders or wood spiders because they like to live in woody areas such as forests, sheds, and woodpiles. The tropical or brown huntsman (Heteropoda) is also large and hairy, with mottled brown, white and black markings. Huntsman spiders use venom to stun their prey and to aid in digestion. Since their discovery, entomologists have identified a number of spiders in the Sparassidae family similar in size to the giant huntsman spider, many hailing from the Greater Mekong Subregion in Southeast Asia.

Several species of huntsman spider can use an unusual form of locomotion. Many huntsman spiders, especially Delena (the flattest), and including Isopeda, Isopedella and Holconia, have rather flattened bodies adapted for living in narrow spaces under loose bark or rock crevices. The Australian Museum respects and acknowledges the Gadigal people of the Eora Nation as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. The effects vary, including local swelling and pain, nausea, headache, vomiting, irregular pulse rate, and heart palpitations, indicating some systemic neurological toxin effects, especially when the bites were severe or repeated. They have been known to inflict serious defensive bites on humans.[7]. [11] Some tropical species like Heteropoda venatoria (Cane huntsman) and Delena cancerides (Social huntsman) have been accidentally introduced to many subtropical parts of the world, including New Zealand (which has no native sparassid species).
