Tarantulas

Tarantulas

Tarantulas are hairy spineless joint legged creatures. They are relatively large arachnids and are close to 900 species. The body of these organisms can be classified as prosoma and opisthosoma. Prosoma or the head and opisthosoma or the abdomen is coupled by a pre genital organ around the waist. This pre genital organ forms a part of the prosoma and allows opisthosoma free movement. The body length of tarantulas varies from around 1 inch to 4 inches and the leg span is around 3 to 12 inches. They weigh about 80 to 150 grams. All of these creatures can produce silk and their food is mainly insects and other arthropods. These venomous creatures generally exist in tropical and desert regions of the world. Some people also consider them as pets and the number of such people is steadily increasing. They are considered as best examples for spiders due to the large species that exist.

Reproduction in Tarantula

The reproduction of Tarantulas is quite contrasting compared to other species of spiders. When the male spider attains maturity it weaves a web on which it dissipates semen and on its pedipalps it would thrust this semen. It would then look for a female tarantula which is ready for mating. Upon identifying its partner, the male would interpose its pedipalps into the female’s opisthosoma around the abdomen region and transfers the semen. Once it transposes the semen the male would try not to confront the female as they tend to be very aggressive after mating. Tarantulas would generally produce from 50 to 2000 eggs.

The hair which tarantulas possess is used by them for protection from their predators. These are also consumed in some parts of the world such as Cambodia. The hair they have is generally harmless though in some cases it was reported to causes eye loss.
