Sometimes quiet and sometimes defensive, the Brazilian Whiteknee Tarantula is a very popular tarantula species among the breeders because of their spectacular look and their nature.
We are presenting to you a medium-sized tarantula with a lot of personality. They can reach a leg span from 6 to 8 inches (15 to 22cm). As their name suggests, they’re native from Brazil.
This is a terrestrial species that usually has a quiet life while in the wild, while of course, taking care of their needs appropriately. If you’re a fan of the spiderwebs, then this tarantula is not for you, as they don’t do so. They are primarily nocturnal and, during their active hours, they will spend the time finding their prey, which can be many types of insects and sometimes tiny rodents.
Their bite is not dangerous, but they can throw urticating hairs, which are known to cause a very unpleasant sensation in the human skin. However, if you keep them unbothered, they can be excellent pets to keep! Their extravagant look is something that you won’t want to take your eyes off.
This tarantula can sometimes be a bit moody, but a beginner can keep them if they take the necessary cares. However, you should get another kind of tarantula if you think that you aren’t able to handle this one correctly.
Lifespan and Physical Characteristics
They have considerable longevity, compared to other tarantula species of the same size. Females can live up to 16 years, but the usual life expectancy is of 14 years. As usual with many tarantula species, the males have a shorter lifetime; it varies from 4 to 6 years.
There are a lot of things that make this kind of tarantula interesting, but the main thing that will catch your eye is their unusual white coloration around their legs. They usually have dark shades of brown that sometimes can look as dark as black, but something that they will always have is the white coloration around their legs, which sometimes can reassemble a skeleton. There is not a vast difference between the sexes, the males and the females are pretty much the same, except for their size. Once they’re adults, you will quickly notice which one is who.
They have a lot of personality. Although they can be aggressive when bothered, they don’t represent a real danger to humans. The Acanthoscurria Geniculata is a terrestrial species which likes to dig, so their terrarium must have enough substrate for them to dig their hideout, in which they will spend most of the time. They will see the entrance with their web, so once they have done it, you will quickly notice where it is. They are pretty easy to take care of and will be amazing pets if either if you have started breeding tarantulas or if you have experience already.
Acanthoscurria Geniculata Handling and Bite
Their bite isn’t really strong, but even though they can’t do that, you have other things to worry about if you’re thinking of bothering this pretty fellow. When feeling threatened or when bothered constantly, they will throw urticating hairs at you, which will cause a very unpleasant sensation in the zone they impact. However, if you know what you’re doing and handle them properly, you can prevent this from happening. As mentioned earlier, they are usually quiet and don’t represent a real danger to humans unless you have an allergy to them. Besides that, you should be able to have everything under your control. As usual, if you notice the tarantula is starting to get defensive, you should leave it alone.
Their diet should be varied, but you can easily feed them with cockroaches and crickets, the usual tarantula food. You can try and give them different kinds of insects which don’t outgrow the tarantula, and once in a while, a tiny rodent. This should be enough to keep your tarantula well-fed and healthy.
Care & Housing
Acanthoscurria Geniculata Habitat
The Brazilian Whiteknee Tarantula is a medium-sized tarantula, so finding a good terrarium for them is not that complicated. For an adult, a perfect size for a terrarium should be of around 30x40x30cm, but you can get another size depending on how big your tarantula is. As they are underground most of the time while in the wild, you must provide enough substrate so they can dig their hideout, where they will spend most of the hours of the day as they are nocturnal animals. Putting the terrarium near a window should be enough for a good illumination, and the decoration is up to you; however, do not spend too much in decoration the surface of the terrarium as your spider will be most of the time underground. They will rarely be seen walking outside their hideout.
The temperature levels should be adjusted, so your tarantula doesn’t die out of stress. A suitable temperature for the Brazilian Whiteknee Tarantula is around 77°F (25°C). During the night, as usual, you can lower the levels a bit, up to 69.8°F (21°C). To maintain the humidity levels, you can put some plants around. The humidity levels for the cage should be about 75-80%.
Reproduction and Breeding
Their reproduction in captivity isn’t that hard to achieve, and the process will be completed quickly. The female does not suppose a real danger to the male and won’t eat it after the copulation is done, something different than most species of tarantulas. As they are usually quiet, you can expect the process to be like this as well. After the mating is done, the female will produce an egg sac after 2 or 3 months. You can introduce the male to the terrarium eight weeks after the female has reached the sexual maturity (after the first molt). These tarantula species lay a large number of eggs, so you can expect several spiderlings to hatch from the cocoon. A usual number of spiderlings hatching from the egg sac is around 500 and 1000.
The Acanthorscurria Geniculata can be a fantastic pet if you take care of it properly. Although they sometimes are aggressive, the situation can always be controlled, and you don’t have to worry about a painful bite. However, as we mentioned, they are capable of throwing urticating hairs when bothered for too much time, so it’s better to leave them alone if they don’t want to be touched or if you are a beginner and don’t know how to handle them in case something like that happens. However, despite that, you can easily take care of them!
Their feeding isn’t that complicated so you won’t have too much problem with that. The coloration that this spider has is really beautiful; it’s something that you will want to see every day. They can be excellent pets if you learn how to take care of them properly, or if you have enough experience, you can enjoy their company for a while.
Despite being very popular among the breeders, there are some who don’t recommend the Acanthoscurria Geniculata to beginners since they can be sometimes hard to handle; in our opinion, handling this tarantula has an intermediate difficulty.
