Discover the African Barking Spider: Interesting Facts and Habitat

Barking Spiders⁚ A Fascinating Family

Barking spiders, also known as whistling spiders, are a group of spiders that belong to the family Theraphosidae. These fascinating creatures are known for their unique ability to produce a loud hissing or barking sound when threatened. This sound is created by rubbing rows of spines on their palps against spines on their lower jaw.

While there are several species of barking spiders found in various parts of the world, the "African Barking Spider" is not a recognized scientific name. It's likely that the term is used informally to refer to certain species of tarantulas found in Africa, particularly those that have a similar appearance or behavior to the well-known Australian barking spider (Selenocosmia stirlingi).

Barking spiders are primitive spiders called Mygalomorphs, which means mouse-like. They have gill-like lungs that require humidity, making them well-suited to living in burrows in moist environments. These spiders are built for digging and spend most of their lives in the underground.

One notable African species often referred to as a "barking spider" is the Caerostris sexcuspidata, also known as the common bark spider. This spider is a nocturnal orb-web weaver found in Southern Africa and on islands off the east coast of Africa. The female constructs a large orb web, sometimes reaching 1.5 meters across, stretching between trees or shrubs.

It is important to note that the specific characteristics and behaviors of African barking spiders may vary depending on the species involved. Further research is needed to fully understand the diversity and specific adaptations of these fascinating creatures.

The Barking Sound⁚ A Defensive Mechanism

The barking sound produced by these spiders is a crucial part of their defense strategy. It's not a true bark, but a hissing or whistling noise created by a unique anatomical feature. Barking spiders have rows of spines on their palps (leg-like appendages near their mouth) and on their lower jaw. When threatened, they rub these spines together, producing a loud and startling sound. This noise serves to deter potential predators, making them think twice before attacking.

Habitat and Lifestyle⁚ Burrow Dwellers

Barking spiders are primarily fossorial, meaning they are adapted for digging. They spend most of their lives in burrows, which they construct in sandy, loamy soil found in arid areas. These burrows provide them with a safe haven from predators and harsh weather conditions. They are also essential for maintaining humidity, which is crucial for the spiders' gill-like lungs. The burrows often have leaky roofs, which help to prevent the spiders from drowning during flash floods. The hairs on their bodies trap air bubbles during such events, providing them with an air pocket to survive.
