The Biggest Animals Kingdom and in The World | Tarantula | The eight legs, the two chelicerae are mounted with their fangs and pedipalps of the prosoma. The chelicerae contain the venom glands that vent through the teeth. The teeth are hollow extensions of the chelicerae, the poison into their prey or animals that the tarantula bites in defense and also used to inject chewing. The chelicerae of a tarantula completely contained around the venom glands and the muscles around it, and can cause the venom is injected into the power dam.The two of the six segments pedipalps appendages is connected to the chest near the mouth of each side and both chelicerae. In most species of tarantula that contain pedipalps sharp knife to cut and chop the food as often coxae or baking.

As with other spiders, the terminal portion of the male pedipalps function as part of their reproductive organs. Male spiders in a silken platform (sperm web) spider on the floor, on the. Sperm released from glands in their opistoma Then add their pedipalps into the semen, absorb the semen into the pedipalps, and later insert pedipalps (one at a time) in the female genital tract, located in the abdomen. The terminal segments of the pedipalps of male tarantulas are moderately larger in circumference than those of a female tarantula. Male tarantulas have special lines around the genital opening. Silk for the sperm web of the tarantula from these special lines oozing.

A tarantula has four pairs of legs and two pairs of appendages. Also at the end of each leg, wherein the couplings, surrounds a group of hairs. These hairs, called Scopula help the spider for better grip when climbing surfaces like glass. The fifth pair are the pedipalps which. The muscles of the legs of a tarantula make the legs bend of the joints, but a leg extending tarantula takes the pressure of blood entering the leg.Unlike most of the species of spiders in Araneomorphae subordination, which contains most of the existing species of spiders, most of which six species of tarantula are then two or four rows. The lines are flexible tubular structures that radiates its spider silk. The tip of each line is as spiders field.

The mouth of the tarantula is removed under his chelicerae in the lower front of the prosome. The tarantula digestive organs (stomach) is a tube extending the length of its body. When the powerful abdominal muscles contract, aspiration of stomach in cross section, creating a strong suction effect, the tarantula increases prey through the mouth and intestinal aspirate can liquefy. After feeding the radicals are formed in a small sphere of the tarantula and discarded. A tarantula central nervous system (brain) is at the bottom of the inner prosoma. A tarantula perceives its surroundings primarily via sensory organs called bristles (hairs or spines). Although a tarantula has eyes, touch the acute and hunting, which depends mainly on the vibrations emitted by the movements of their prey. A tarantula bristles are very sensitive organs and are used to detect chemical signals, vibrations, wind direction, and perhaps even sound.

The eyes are located above the chelicerae before the prosoma. Arboreal tarantulas generally have better vision compared with terrestrial tarantulas. In all, there are two sets of book lungs tarantulas (respiratory system). When the air enters each lung, oxygen is introduced into the blood stream through the blood vessels of the lungs. In America, these insects called "tarantula hawks", being parasitoids of tarantulas. The largest tarantula hawks, such as those of the genus Pepsi will follow, to attack and kill large tarantulas. They use scent find the hiding place of a tarantula. The wasp then seals the spider in its burrow and flies in search of more users.

Some other arthropods, such as giant centipede also known to prey on tarantulas. Besides the normal "hairs" covering the body, some tarantulas also have a dense covering of irritating hairs called urticating hairs on the opisthosoma, which are sometimes used as protection against enemies. These hairs are in the species of the New World, but not in samples from the Old World.Some people are extremely sensitive to these hairs, and develop serious itching and rashes on the website. The exposure of the eyes and respiratory system to urticating hairs should be strictly avoided. Species with stinging hairs can kick these hairs off: air travel to a destination with their colleagues back of the legs. Tarantulas, these hairs for other purposes, such as to mark territory or to line their shelters (the latter such practice may discourage flies feed on young people). Stinging hairs grow back, but replaced with each moult. The intensity, the number, and buoyancy of the hair depends on the species of tarantula. Many Owners Goliath Bird Eaters (T. blondi) claim that have the worst Theraphosids stinging hairs

In some cases, tarantula hairs have caused permanent damage to human eyes.Some hairs are stridulate for, creating a hissing sound. These hairs are usually found on the chelicerae. Although it bites no deaths have been attributed to tarantula, spider bites are sometimes as the likely source of infection seen. Stinging hairs can cause health problems for humans, the eyes and the respiratory tract. Like other spiders, mechanical conditions are very different. When a male spider detects the presence of a female, the two exchange signals prove that they are the same species. If the female is receptive to male then approached and inserts his pedipalps into an opening on the underside of their abdomen, called the opisthosoma. Although women may show a little 'aggression after mating, the male is rarely a 50 to 2000 eggs meal.Females deposit, depending on the species remains in a silken cocoon and protect it for 6-7 weeks. For most species, turns the female egg sac often called the incubation period.
