Huntsman spider is a name given to the familySparassidae (formerly Heteropodidae). They are also known as the giant crab spiders, due to the way they look. Larger ones, are also sometimes referred to as wood spiders, because they live in woody places (forest, mine shafts, woodpiles).
Huntsman spiders do not build webs, but hunt for food.[1] They eat insects and other invertebrates.
The average huntsman spider is about 1 inch long with a leg span of up to 5 inches. The giant huntsman spider, however, has a leg span of up to 12 inches, making it the largest spider by diameter; it is often described as being "the size of a dinner plate."[2]
