The tarantula's digestive organ (stomach) is a tube that runs the length of its body. Theraphosa blondi. The fangs are hollow extensions of the chelicerae that inject venom into prey or animals that the tarantula bites in defense, and they are also used to masticate.

The chelicerae are two double-segmented appendages located just below the eyes and directly forward of the mouth. After feeding, the leftovers are formed into a small ball by the tarantula and thrown away. A likely candidate for the true identity of this spider is the dangerous Brazilian wandering spider (Phoneutria fera) of the family Ctenidae, as it is sometimes found hiding in clusters of bananas and is one of several spiders called "banana spiders".
Two other species, Lasiodora parahybana (the Brazilian salmon birdeater) and Lasiodora klugi, rival the size of the two goliath spiders.
Theraphosa apophysis is very similar to Theraphosa blondi and Theraphosa stirmi except for very subtle differences. The chelicerae contain the venom glands that vent through the fangs. on their own after maturation. Theraphosa apophysis has far more setae/hair on it’s legs in general, with a much more noticeable pinkish/reddish hue over the body. Some Australians use the slang term "triantelope" (a corruption of the incorrect term tarantula, which is also used) for large, ″hairy″, and harmless members of the huntsman spider family, which are often found on interior household walls and in automobiles.[25]. Another dangerous type of spiders that have been confused with tarantulas are the Australian funnel-web spiders. Within most species, the females turn the egg sac often, which is called brooding. [12] The term "tarantula" was subsequently applied to almost any large, unfamiliar species of ground-dwelling spider, in particular to the Mygalomorphae and especially the New World Theraphosidae. The eight legs, the two chelicerae with their fangs, and the pedipalps are attached to the prosoma. The spider originally bearing the name "tarantula" was Lycosa tarantula, a species of wolf spider native to Mediterranean Europe. [32], As with other spiders, the mechanics of intercourse are quite different from those of mammals. A tarantula's setae are very sensitive organs and are used to sense chemical signatures, vibrations, wind direction, and possibly even sound. 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. 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.

All types of tarantulas have two sets of book lungs (breathing organs); the first pair is located in a cavity inside the lower front part of the abdomen near where the abdomen connects to the cephalothorax, and the second pair is slightly farther back on the abdomen.
They are considered a delicacy in certain cultures (e.g. So register an account on our online store to stay in touch. (2019, May 1). These spiders are members of the same suborder as tarantulas, Opisthothelae. These fangs are articulated so that they can extend downward and outward in preparation to bite or can fold back toward the chelicerae as a pocket knife blade folds back into its handle.
Arboreal tarantulas generally have better vision compared with terrestrial tarantulas. Other species occur variously throughout Africa, much of Asia (including the Ryukyu Islands in southern Japan), and all of Australia. Prey with large amounts of solid parts, such as mice, must be crushed and ground up or predigested, which is accomplished by coating the prey with digestive juices secreted from openings in the chelicerae. They are not great as display tarantulas because they love spending time in their hides or burrows. Reproduction in whole or in part without permission is prohibited. Theraphosa apophysis (the pinkfoot goliath) was described 187 years after the goliath birdeater, so its characteristics are not as well attested.T. Theraphosa apophysis … The Theraphosa genus belongs to the tarantula family, A juvenile male's sex can be determined by looking at a cast exuvia for exiandrous fusillae or spermathecae.

Life span: Goliath bird eating spiders m ales live shorter lives than females, between 2 and 5 years. They use olfaction to find the lair of a tarantula.
[citation needed][11], Females deposit 50 to 2,000 eggs, depending on the species, in a silken egg sac and guard it for six to eight weeks. Male tarantulas rarely molt again once they reach adulthood, but they may attempt to do so, usually becoming stuck during the molt due to their sexual organs and dying in the process. [11] The name is derived from the southern Italian town of Taranto. Urticating hairs do not grow back, but are replaced with each molt. Currently, about 1,000 species have been identified.
