| Phlogiellus ingens | Australian Tarantula (eastern states) | Up to 20 cm | Woodlands, open forests, shrublands |

Giant Huntsman Spider Identification
The giant huntsman spider is often cited when discussing the world's biggest spider in Australia. With long, banded legs splaying out, it has a crab-like appearance. Its body is relatively flat, and it moves quickly across surfaces, which can startle observers.
Habitat and Distribution Across Australia
This species prefers warm, sheltered environments such as rock fissures, under loose bark, and cave entrances. It is commonly found in northern Australia, including Queensland and Western Australia, though it sometimes appears in human-made structures seeking dark, stable conditions.
Behavior and Hunting Strategies
Unlike web-building spiders, the giant huntsman relies on active pursuit. It uses its speed and stealth to ambush prey, mostly insects and other small arthropods. Its nocturnal activity pattern means encounters with humans are more likely at night, especially near lights that attract insects.
