Tarantulas are spiders belonging to the family theraphosidae. Most of the species are large and hairy, but there is a smaller species as well. There are about 900 known species of tarantulas and tarantulas found all over the world, ranging from tropical to desert areas. Some species of arboreal while others live and hunt on the ground. The tarantulas name originally refers to the European wolf spider alone and can be traced to the Italian city Taranto. Name was then applied to all European spider Theraphosids when beginning to explore the areas that have many large spiders, such as the United States.
Tarantula is a predator that attacks mainly eat other insects, but larger species will also eat small reptiles, amphibians, mice and birds that have made them known as bird spiders. Tarantulas are venomous and use poison to kill prey. However most of the species are not harmful to humans. The most dangerous species produce toxins that can cause extreme discomfort, sometimes for many days, but the bite will not kill them except for allergic reactions occur. No deaths have been associated with the spider tarantulas. While they do not spin nets for hunting, all species of tarantulas can make a silk each species in a tent to sleep much silk, while others use silk to reinforce the wall in their pores. They can also use silk to help them up.
Tarantula has anatomy similar to other spiders, and you can read more about the anatomy of a spider to visit parts of our spider.
Some species of tarantulas show dimorfisme sexual males are usually smaller and have a dull coloration than females. Males in several species have linked tibialis used to hold the female while mating. Tarantulas teen sex can be determined by the fact that male tarantulas have exuvium cast for fusillae exiandrous or spermathecae, while women do not. It is also possible to perform ventral sexing but this is less reliable, especially since it was difficult to make that true.
Tarantula males have a shorter life span than women, and many die soon after maturity, something that happens in 2-10 years depending on the species. Female tarantulas can live up to 30-40 years when stored in good condition in captivity. The oldest tarantulas live to 49 years. This age may be very large in the wild because predasi. There are many animals that eat tarantulas, including parasitic wasps, tarantulas eagles, which nest on the tarantulas and spiders leave a food source for larvae.
In the pet trade, females are more sought after and therefore quite often more expensive. This is mainly due to the fact that they live longer. Most wild caught tarantulas are man who may not have much longer to live. This male-female ratio skewed due to the fact that the man while roaming in more than women living in and close their pores. Because men are more likely to end at the hands of catchers tarantulas.
Tarantula reproduce through internal fertilization. Men entered into the pedipalpus opithosoma female spider, the opening in the lower abdomen. Man get his semen to pedipals by releasing sperm into the web it was spinning on the ground and then inserts a small pool pedipalpus in semen. The pedipalpus absorb semen and store it until a compatible woman could be found. Men should leave the scene quickly after mating or female may eat her husband's male ones. But actually eaten rarely if there is enough space for men to retreat. After mating, female tarantulas eggs 50-2000 (depending on the size and type). The eggs are stored in a silk bag and guarded by the female until hatched offspring after 6-7 weeks. Young spiders still have some left their yolk sac and will live on the first day before leaving the safety of her pores. Young spiders like this are often referred to as a spider.
