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, pantropical huntsman spider or cane spider. [1]

Description

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]

Biology

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]

The spider is not considered dangerous, but it does deliver enough venom to give a painful bite. [1] [4]

Prey

The spider feeds on insects, which includes various species of butterflies and moths such as Deilephila elpenor . The spider captures them directly instead of spinning webs. After capturing its prey, the spider injects them with venom. [1] The venom of this spider contains the toxin HpTX2, a potassium channel blocker. [5] In some tropical areas the spider is considered a useful resident of households because of its efficient consumption of pest insects. [1] It commonly lives in houses and other structures such as barns and sheds, especially in areas that experience cold temperatures. It is sensitive to cold and can live outdoors only in warmer climates. [1] In Bermuda, where they are mostly found indoors, they are generally called house spiders (which may cause its identity to be confused with the Southern house spider), [6] or sometimes wolf spiders. [7] [8] [9] (Not to be confused with Lycosidae, which are also called wolf spiders.)

Besides insects it has been known to prey on scorpions and bats. [2]

<i>Latrodectus mactans</i> Species of spider

Latrodectus mactans, known as southern black widow or simply black widow, and the shoe-button spider, is a venomous species of spider in the genus Latrodectus. The females are well known for their distinctive black and red coloring and for the fact that they will occasionally eat their mates after reproduction. The species is native to North America. The venom can cause pain and other symptoms, but is rarely fatal to healthy humans.

<span class="mw-page-title-main">Huntsman spider</span> Family of spiders (Sparassidae)

Huntsman spiders, members of the family Sparassidae, are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places. In southern Africa the genus Palystes are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related.

<i>Parasteatoda tepidariorum</i> Species of spider

Parasteatoda tepidariorum, the common house spider or American house spider, is a spider species of the genus Parasteatoda with a cosmopolitan distribution. Common house spiders are synanthropic and live in and near human dwellings. Their prey mechanism is similar to that of the other cobweb spiders: the spider follows disturbances transmitted along the web to entangle and then paralyze its prey, which usually consists of household insects and other invertebrates.

The Goliath birdeater belongs to the tarantula family Theraphosidae. Found in northern South America, it is the largest spider in the world by mass and body length, and second to the giant huntsman spider by leg span. It is also called the Goliath tarantula or Goliath bird-eating spider; the practice of calling theraphosids "bird-eating" derives from an early 18th-century copper engraving by Maria Sibylla Merian that shows one eating a hummingbird. Despite the spider's name, it rarely preys on birds.

<span class="mw-page-title-main">Southern house spider</span> Species of spider

The southern house spider is a species of large spider in the family Filistatidae. Currently given the scientific name Kukulcania hibernalis, it was formerly known as Filistata hibernalis. Found in the Americas, it exhibits strong sexual dimorphism. It lives in the southern states of the USA, throughout Central America and some of the Caribbean, to southern Brazil, Uruguay and Argentina. The males may be mistaken for brown recluses because the two have similar coloration and body structure. However, compared to the brown recluse, male southern house spiders are typically larger in size, lack the distinctive violin shape on their cephalothorax, and have unusually long slender pedipalps. The females are dark brown or black and more compact. Both sexes may grow to be roughly 2 inches (5.1 cm) across, with the males typically having longer legs, and the females often having larger, bulbous bodies. The abdomen of the southern house spider is covered with fine velvety light gray hair.

<span class="mw-page-title-main">Tarantula</span> Family of spiders

Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.

Hysterocrates gigas is a member of the tarantula family, Theraphosidae found in Cameroon. It is known as the giant baboon spider, Cameroon red baboon spider, or red baboon tarantula.
