Huntsman spiders are famous for their enormous leg span, fast movement, and intimidating appearance. These spiders belong to the Sparassidae family and are found mainly in warm tropical regions around the world. Some species grow so large that they are considered among the biggest spiders on Earth by leg span. Australia is especially known for giant huntsman spiders, although the world’s largest huntsman species was actually discovered in Laos. Despite their frightening appearance, huntsman spiders are usually shy hunters that avoid humans and rarely cause serious harm.
What Is a Huntsman Spider?
Huntsman spiders are large fast-moving spiders known for their flattened bodies and wide sideways legs. Unlike web-building spiders, huntsman spiders actively chase insects and other prey at night. Their crab-like movement and huge leg span often surprise people when they appear on walls, ceilings, or trees.
Huntsman Spider Scientific Classification
Huntsman spiders belong to the Sparassidae family, which includes many tropical and subtropical species found across Asia, Australia, Africa, and the Americas.
Why Huntsman Spiders Look So Large
Several features make huntsman spiders appear enormous:
- Extremely long legs
- Wide sideways leg posture
- Flattened body shape

Huntsman Spider Size and Appearance
Huntsman spiders are specially adapted for climbing and rapid movement. Their body structure helps them spread their legs widely across flat surfaces.
Leg Span Measurements
The largest huntsman spiders may stretch nearly a foot across from leg tip to leg tip, creating a startling appearance indoors or on trees.

Baby Huntsman Spider Growth
Young huntsman spiders begin life very small but grow rapidly through repeated molting stages. Each time they shed their outer exoskeleton, their body and legs become larger.
Growth Through Molting
Baby huntsman spiders may molt several times before reaching adulthood. During this process, they temporarily become soft and vulnerable until the new exoskeleton hardens.

In warm tropical climates, huntsman spiders may reach adult size within one to two years depending on species and food availability.
