Lycosa tarantula carrying her offspring. Tarantism (/ ˈ t ɛr ən ˌ t ɪ z əm / TERR-ən-tiz-əm) [1] is a form of hysteric behaviour originating in Southern Italy, popularly believed to result from the bite of the wolf spider Lycosa tarantula (distinct from the broad class of spiders also called tarantulas).
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".
Abnormal behaviour in animals can be defined in several ways. Statistically, abnormal is when the occurrence, frequency or intensity of a behaviour varies statistically significantly, either more or less, from the normal value. This means that theoretically, almost any behaviour could become abnormal in an individual.
New World tarantulas will, at the moment of danger, turn toward the attacker and briskly rub their hind legs against the opisthosoma throwing the urticating hairs in the direction of the enemy. The cloud of small bristles can get into the mucous membrane of small mammals and cause edema , which can be fatal.

Pterinochilus murinus or the orange baboon tarantula, [2] is a nocturnal spider in the family Theraphosidae that was first described in 1897 by Reginald Innes Pocock. [1] This species is found in Angola, as well as central and southern Africa. It is a member of the subfamily Harpactirinae, baboon spiders. [3]
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.
When threatened, the tarantula will raise its legs in the air, as well as the front of its body, in order to deter predators. If the attacker continues to attack, the tarantula will bite. The Brazilian salmon pink tarantula is capable of delivering a painful bite. They are known to bite only when provoked, and even then, this is a last resort.
