Urticating hairs or urticating bristles are one of the primary defense mechanisms used by numerous plants, almost all New World tarantulas, and various lepidopteran caterpillars. Urtica is Latin for "nettle" (stinging nettles are in the genus Urtica ), and bristles that urticate are characteristic of this type of plant, and many other plants in ...
Tarantulas often hold this position for longer than the duration of the original threat. Their next step, without biting, may be to slap down on the intruder with their raised front legs. If that response fails to deter the attacker, the tarantulas of the Americas may next turn away and flick urticating hairs toward the pursuing predator. The ...
It is an Old World tarantula, so has no urticating hairs; its only defenses are biting and fleeing. This tarantula is known to have more potent venom than many tarantula species [ citation needed ] , but Cyriopagopus albostriatus venom was shown in a study to have the ability to regulate activity in voltage-gated sodium channels, which are ...
They are distinguished from true spiders by their two pairs of book lungs, vertically oriented chelicerae, and urticating setae. However, like all members of Psalmopoeus , P. irminia lack these urticating hairs but make up for it by having stronger venom compared to other New World tarantulas.
Although it has hairy legs, this tarantula is an Old World species and does not have urticating hairs on its abdomen. (Urticating hairs are hairs found in most new world species (those from North and South America) that can be shed in defence, they are barbed and may cause severe itching.) It also has a leg span which may reach 8 inches (20 cm).
They lack urticating hairs and are arboreal, often found in tree cavities. Many species have "dimples" on the abdomen, but this feature is not universal. Although their behavior is defensive, they lack both urticating hairs and the ability to stridulate, giving them a very mild venom. Their egg sacs can contain up to 200 spiderlings.
It includes nearly all the North American tarantula species north of Mexico and a considerable percentage of the tarantula species that range into Central America. Most are fairly large tarantulas with leg spans of 6 in (16 cm) or more. Like most New World tarantulas, all species of Aphonopelma have urticating hairs. Despite their fearsome ...
Additionally, A. hentzi and most other tarantulas found in the Americas have small, coarse, brown or black urticating hairs on their abdomens that they kick in the direction of whatever they may feel threatens them. It is the main species preyed upon by the tarantula hawk, Pepsis grossa, in areas where the two species overlap. [9]
