Humans' reaction and the degree of irritation to a defensive urticating hair barrage can vary tremendously, based on the species in question. Some, such as those of the Chilean rose tarantula ( Grammastola rosea ) and the pinktoe tarantula ( Avicularia avicularia ), are fairly mild and innocuous to humans.
A spider bite, also known as arachnidism, is an injury resulting from the bite of a spider. The effects of most bites are not serious. [1] Most bites result in mild symptoms around the area of the bite. [1] Rarely they may produce a necrotic skin wound or severe pain. [2]: 455 Most spiders do not cause bites that are of importance.

These urticating hairs can be harmful to humans. [9] Like all tarantulas, T. blondi spiders have fangs large enough (2–4 cm or 0.79–1.57 in) to break the skin of a human. They carry venom in their fangs and have been known to bite when threatened, but the venom is relatively harmless and its effects are comparable to those of a wasp's sting
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] 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".
The movements of the frog do not stimulate the host tarantulas to attack and there is an unknown chemical present in the frog's skin that acts as a cue to the tarantulas that this species is not prey. [9] The spiders did attempt to catch and eat five species of frogs from the families Bufonidae, Hylidae, and Leptodactylidae. It is noted that ...
Old-world tarantulas, especially those indigenous to Asia, lack urticating hairs and may bite as a defensive mechanism. They are far less docile than new-world tarantulas, and are more likely to bite when provoked. Hobbyists report bites by Poecilotheria species, occasionally resulting in hospitalization. Symptoms include localized pain and ...
The video above shows the fascinating way male giraffes fight. Known as “necking” the giraffes use their long and powerful necks to attack, delivering hard blows with each hit.
The bite from an Eastern tarantula is not fatal to a human, but can cause up to six hours of vomiting.The venom can cause death to a dog or cat within thirty minutes. [3] [8]In May 2010 a scientist living near Cooktown, Queensland, was bitten on her right index finger and experienced symptoms never reported before in research literature.
