Biology and Physical Characteristics
The huntsman spider belongs to the Sparassidae family, which is renowned for its large size, hair-covered body, and long legs. Unlike traditional spiders that have forward-facing legs, huntsman spiders have laterigrade legs, which extend sideways, giving them a crab-like appearance. Adult huntsman spiders can have a leg span of up to 15 cm (6 inches) or more, making them one of the largest spider species in terms of sheer size.
These spiders are typically brown, grey, or beige, with some species featuring unique patterns or markings on their bodies that help them blend into their surroundings. Their eight eyes are arranged in two rows, providing them with excellent vision, which is crucial for their hunting lifestyle. Unlike web-building spiders, the huntsman relies on its agility and speed to catch prey, a behavior that aligns with its biological adaptations.
Their bodies are divided into two main parts: the cephalothorax (fused head and thorax) and the abdomen. The cephalothorax houses the spider’s powerful jaws (chelicerae), which are used for gripping and consuming prey. These spiders also have pedipalps near their mouths, which they use for sensory functions and mating in males.
Habitat and Distribution
Huntsman spiders are primarily found in tropical and subtropical regions across the globe, with notable populations in Australia, Asia, Africa, and the Americas. They thrive in warm climates and are commonly found in forests, grasslands, and deserts, as well as urban areas where they often seek shelter in homes, sheds, and garages.
In their natural habitats, these spiders prefer hiding under loose bark, rocks, and leaf litter. Their camouflage capabilities are exceptional, allowing them to blend seamlessly into their surroundings. In urban settings, they are often spotted on walls, ceilings, and even inside vehicles, where they seek refuge from predators and environmental changes.
Despite their wide distribution, huntsman spiders are highly adaptable, capable of surviving in various conditions. This adaptability is one of the reasons they have become so widespread and successful as a species. Their preference for warm environments means they are less commonly found in colder regions, although some species have been known to adapt to temperate climates.
