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.
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 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).
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.
