Brachypelma

Brachypelma is a genus of spiders in the family Theraphosidae (tarantulas), found in Mexico and Central America. They may have bodies up to 6 cm long with legs of similar or greater lengths. Some species have brightly colored legs, with red or orange marks and rings. The taxonomy of the genus and its species has been the subject of considerable debate.

As of October 2017, the genus contained 18 species, which fall into two groups: “red leg” tarantulas and “red rump” tarantulas. Many species are popular with tarantula keepers as pets; the females in particular are long lived. All species of Brachypelma are protected, and trade is regulated under CITES. Although they are bred in captivity, they continue to be exported in large numbers. Members of the “red leg” group are considered to be in most urgent need of further conservation efforts.

Biology

Mexican Radey’s Trentulus companion in the summer, shortly after the male’s maturity in the rainy season Mating is found in or near the woman’s bone, where the male uses her podipalpeps (front organs), which is to open her sperm in the lower right corner of the female. After mating, some women have tried to kill and eat a man, although he has never been seen in wild. Sperm and eggs are stored in female body and do not stand until springtime.

In the spring, hundreds of female deposits make eggs and sperm in a silk mat, and then make this mat a ball or an egg sack. Fertility is done in minutes and spiderlose is in less than three months , but spiders stay in egg-cathom for more than three weeks. Once an egg-squeezes pass out two weeks before it is dispersed. Approximately four years of age and females mature in about six or seven years after two to three years. They are a long-standing species of living aged between 25 and 30; However, after men’s maturity only live one year.

Habitat

A burrowing species, the curlyhair tarantula is found in tropical rainforest regions, either around the base of large trees, near rivers, or in patches of cleared rainforest.

Color

The Red Knee tarantula is found in Mexico, south-western United States and Panama. They are quite common now to be kept as pets as they are slow growers and they have a beautiful body in colour and shape. The red knee tarantula also has a bite that could hurt a human but would not be harmful.

Due to the relatively small size of the red knee tarantula, the red knee tarantula has many predators across Central America. Birds, large reptiles and various mammal species all prey on the red knee tarantula, often waiting until the red knee tarantula comes out of its burrow before attacking it.

History

All the species of Brachypelma that have been studied in detail live in burrows. These have a single entrance, a little larger than the spider, opening into a horizontal tunnel that usually leads to two chambers: one where it molts and one where it rests and consumes its prey. The entrance is blocked with material, such as soil and leaves, bound together by silk when the spider is inactive for significant length of time; otherwise the entrance is open with some silk visible. North American tarantulas like Brachypelma are “sit and wait” predators, seizing prey passing by the burrow entrance.

Compared to related genera, Brachypelma species are long-lived. The maximum life-span recorded in two Berlin zoos was 12 years for Brachypelma annitha (now a synonym of B. smithi). In the wild, females take around 9–10 years to reach maturity, but can then live for another 10 years. Males can take 7–8 years to reach maturity, afterwards usually dying within a year,[6] probably because when mature they actively seek mates and rarely feed while doing so, whereas females remain around their burrows.
