Acanthoscurria geniculata

Acanthoscurria geniculata, also known as the Hunter's Knee Tarantula, is one of the most fascinating and largest terrestrial spiders in the world. With its impressive appearance and interesting behavior, it is often sought after by exotic animal enthusiasts and tarantula collectors. This article aims to explore the characteristics and behavior of this species, as well as its natural habitat and importance in the ecosystem.

Acanthoscurria geniculata is native to South America, particularly the central and western parts of Brazil. Its main habitat includes tropical and subtropical forests, where they prefer to live in humid areas and forest edges. These tarantulas are adapted to terrestrial life, being a very agile species capable of moving quickly through foliage and dense vegetation.

This tarantula species is renowned for its impressive size. An adult female can reach a length of up to 20 centimeters, including its long and powerful legs. Males, on the other hand, are much smaller, reaching around 10-12 centimeters in length. This difference in size between genders is common in the world of tarantulas and is primarily adapted for mating.

The physical appearance of Acanthoscurria geniculata is truly impressive. True to its common name, the Hunter's Knee Tarantula has contrasting joints on its legs used for prey hunting. These joints are colored in a pattern of dark and shiny stripes, which attracts attention and gives it an astonishing appearance. Their abdomen is generally black or dark in color, covered with thin hair that gives them a soft and fluffy appearance.

The behavior of Acanthoscurria geniculata is also interesting and different from other tarantula species. These spiders are mostly active at night and hide in their underground burrows during the day. These burrows are manually dug by the tarantulas in the soil, using their strong legs and jaws to release the earth and create a system of tunnels and underground chambers. These burrows serve as shelter and resting places for the tarantulas.

Acanthoscurria geniculata is primarily a predator, feeding on a variety of insects such as beetles, crickets, and other smaller invertebrates. Unlike other spiders, they do not use spider webs to catch their prey but rely on sight and smell to detect and attack moving prey. Once the prey is captured, the tarantula uses its venom to paralyze and gradually digest it.

In addition to being fascinating and impressive, Acanthoscurria geniculata also plays an important role in its natural ecosystem. By hunting and controlling populations of harmful insects, these tarantulas help maintain balance in the ecosystem and control populations of smaller predators. They can also be considered indicators of the health and well-being of the habitat they live in. If their population were to decline, it could signify an imbalance in the local ecosystem.

In conclusion, Acanthoscurria geniculata is a fascinating and impressive species of tarantula native to South America. With its impressive size, astonishing appearance, and interesting behavior, this tarantula is often appreciated and sought after by exotic animal enthusiasts and tarantula collectors. With its natural habitat and importance in the ecosystem, Acanthoscurria geniculata also plays an important role in maintaining balance and proper functioning of the surrounding environment.









The Brazilian white-knotted Tarantula (Acanthoscurria geniculata) is part of the

Species: geniculata.As the common name says, this species is found in Brazil.Individuals of this species live in the wild in the Brazilian selva, in areas with high humidity. The species is terrestrial, therefore individuals live at ground level.

Food Acanthoscurria geniculata

This species will eat almost everything available to it, being one of the few species in which there is a risk of overfeeding. Food is provided every 2 weeks for sub-adult or adult individuals, and approximately once a week for smaller individuals. Some individuals will eat food even during pre-spawning, which is not the case in most species.Features of Acanthoscurria geniculata

Large species, reaching 20 cm legspan, is easily recognized by the white bands from the joints of the limb segments, but also by the black abdomen covered with red hairs. One of the most popular species in the hobby, it is appreciated for its large size, color, fast growth rate and for the fact that they spend most of their time "in sight", unlike other species of tarantulas. It is also an appreciated species for having a voracious appetite and cases in which to refuse food are rare. Being a species native to South America and Acanthoscurria geniculata presents hives on the body, which can cause some inconvenience to the owner of this species (irritation of the dermis in the place of contact with the bristles, severe conjunctivitis and even blindness if they contact the structures of the eyeball).


Acanthoscurria geniculata is a terrestrial species, the surface of the terrarium being more important than the height. They spend most of their time out of hiding, but this is necessary for the animal's safety or a thicker layer of substrate must be provided in which the individual can build a hiding place.

The optimum temperature is around 25-28 grC during the day and should not fall below 18 grC in the night phase, and in terms of humidity, experienced breeders recommend it around 60%. Peat moss, potting soil without organic additives, vermiculite or coconut soil can be used as a substrate. It is also recommended to use a bowl of water to avoid dehydration of the animal. The bowl should be proportioned to the size of the animal so that there is no risk that the individual will fall inside and die drowned because he can not get out.

All species of tarantulas possess venom. Although it is not very potent, bites are never placute.De like any species of tarantula and Acanthoscurria geniculata can be unpredictable and a bite can occur at any time. For these reasons we recommend maximum attention when the tarantula is fed, moved or when its terrarium is cleaned.

It is not recommended to handle tarantulas.

Reproduction Acanthoscurria geniculata

There are more frequent cases in which the female attacks and even kills the male during mating and the fact that a bag with eggs can contain over 2000 eggs.
