Heteropoda venatoria is a species of spider in the family Sparassidae, the huntsman spiders. It is native to the tropical regions of the world, and it is present in some subtropical areas as an introduced species. Its common names include giant crab spider and cane spider.[1]



The adult has a flat, brown body 2 to 2.5 cm (0.8 to 1 inch) long, 7 to 10 cm (3 to 4 inches) wide, including the legs. The female may be slightly larger than the male, particularly in the abdomen, but the male has longer legs and larger tips on its pedipalps. The clypeus, the area just in front of the eyes, is cream or yellowish, and the carapace behind the eyes has a wide band which is usually tan in the female and cream in the male. The body is not very hairy, but the legs have erectile setae, each of which is marked with a black dot.[1]



The female produces an egg sac up to about 2.5 centimeters wide and carries it with its pedipalps under its body.[2] Egg sacs are variable in size, usually containing over 100 eggs, with larger ones holding over 400. The spiderlings undergo their first molt while still in the sac.[2] In one small laboratory sample, the life span of the male averaged 465 days, and that of the female was 580 days.[2]



As part of its courtship behavior, the male produces a sound by vibrating its abdomen while keeping its feet firmly planted. This is faintly audible to humans as a "buzz" or "hum".[3]
