When it came to finding the strength of tarantula fang penetration, though, it wasn’t so easy to measure or find information about. This article is about the spider family, Theraphosidae. In a goliath bird-eating tarantula, for example, these fangs are 1 inch long, delivering a severely painful bite. Names interpreted in this way include:[13]. Many of these, including lizards, frogs, birds, and mammals, are generalist predators of all kinds of large arthropods. The chelicerae contain the venom glands that vent through the fangs. [citation needed] Additionally, the large fangs of a tarantula can inflict painful puncture wounds, which can lead to secondary bacterial infections if not properly treated. They are small and usually set in two rows of four. Although females may show some aggression after mating, the male rarely becomes a meal. Thank you for signing up to Live Science. A Theraphosa blondi (Bird eating tarantula) has fangs that can reach approximately 1 inch long! Worms Frozen for 42,000 Years in Siberian Permafrost Wriggle to Life, Elusive squid seen alive in natural habitat for first time (VIDEO). It was a great suggestion, a lot of people thought it was very interesting . Like other spiders, tarantulas have to shed their exoskeleton periodically to grow, a process called molting. According to Texas Parks and Wildlife Magazine, most terrestrial species of tarantulas are burrowers. A tarantula has four pairs of legs and two additional pairs of appendages. Through chemical analysis and X-ray detection, it was also discovered that their fangs have metal atoms dispersed throughout, mainly copper, magnesium, iron and zinc. Male spiders spin a silken platform (sperm web) on the ground onto which they release semen from glands in their opisthosoma. Interesting information I had no clue metal deposits built up in fangs of T’s. Tarantula fang size definitely depends on the species, but some tarantulas have very big fangs in proportion to their bodies. [19] Other arthropods, such as large scorpions and giant centipedes, are also known to prey on tarantulas.[20]. The eyes are located above the chelicerae on the forward part of the prosoma. Tarantulas are also preyed upon by a wide variety of vertebrates. Often, metal atoms in the newly hardened structures are also paired with specific non-metals: zinc with chlorine, and manganese with calcium. Each spinning field is covered by as many as 100 spinning tubes through which silk is exuded. Old World tarantulas have no urticating bristles and are more likely to attack when disturbed. In fact, tarantulas have become a popular pet for arachnophiles around the world. This can be traced back to Carl Ludwig Koch in 1850,[13] who in describing his new genus Eurypelma wrote "Die Sammetbürste der Fussohlen sehr breit",[14] literally 'the velvet-brush of the footsole very wide'. They are among the most aggressive types of tarantula, and also one of the most rare. When he’s finished, he “makes a quick getaway since females will often try to eat the males after mating,” said Sewlal. They are considered a delicacy in certain cultures (e.g. When the sucking stomach's powerful muscles contract, the stomach is increased in cross-section, creating a strong sucking action that permits the tarantula to suck its liquefied prey up through the mouth and into the intestines. Is this the funniest animal picture ever? 24 December 2014. Tarantulas’ size and coloring can vary wildly depending on location and species. Tarantulas are also very responsive to the presence of certain chemicals such as pheromones. I hadn’t seen much information on it before, and after learning a bit more about the freakish strength that tarantulas possess, I thought it would be great to look into. With humans, they can cause irritation to eyes, nose, and skin, and more dangerously, the lungs and airways, if inhaled. They can even regrow lost legs or pedipalps (short sensory appendages). Wild-caught tarantulas are often mature males because they wander out in the open and are more likely to be caught. The tarantula's digestive organ (stomach) is a tube that runs the length of its body. Retrieved October 13, 2019, from, Fabre, Jean-Henri; Translated by Alexander Teixeira de Mattos (1916), CS1 maint: multiple names: authors list (, Schultz, Stanley A. and Schultz, Marguerite J. Compared to tarantulas, wolf spiders are not particularly large or ″hairy″, and so among English speakers in particular, usage eventually shifted in favour of the Theraphosidae, even though they are not closely related to wolf spiders at all, being in a different infraorder.
