Holconia murrayensis (1 cm)

Holconia murrayensis, commonly known as the Australian Huntsman, is a fascinating arboreal spider that serves as an excellent alternative to classic tarantulas. It is native to Australia, where it inhabits forested areas, hiding during the day under loose eucalyptus bark. Its strongly flattened body (dorso-vertical build) is an evolutionary adaptation to life in narrow crevices, making it a unique inhabitant of a home terrarium. Appearance and Distinctive Features This species stands out primarily for its proportions—it has a relatively small body but very long, widely spaced legs. Its coloration is a subtle blend of gray, beige, and white with darker spots and stripes on its legs, providing perfect camouflage against the backdrop of trees. It has eight eyes arranged in two rows, giving it the excellent vision necessary for active hunting. Behavior and Venom Unlike tarantulas, Holconia murrayensis does not lie in wait for its prey but actively pursues it. It is a spider with phenomenal reflexes and speed, capable of moving instantaneously across vertical surfaces. This species lacks urticating hairs. Its venom is not dangerous to humans; however, due to its high activity level and skittish nature, this spider is recommended for people who already have some experience keeping fast-moving invertebrates. Housing Requirements: It requires a vertically oriented terrarium. A key element of the setup is vertically placed pieces of bark (e.g., oak or cork), which mimic the natural environment and serve as shelter. This spider prefers room temperature (22–26°C) and moderate humidity. Good ventilation is important to prevent stagnant air. A thin layer of peat or coconut fiber is sufficient as a substrate, which will help maintain stable conditions.
