The giant prickly stick insect, Extatosome tiaratum, is known for its unusual spiny appearance. These animals are native to Australia and can be found in various regions across the country. They are typically found in forests, woodlands, and shrublands, where they blend in with the vegetation. The prickly stick insect has a body that resembles a branch covered in thorny projections or spines which serve as a defensive mechanism by deterring predators, providing protection, and making the insect less palatable. The coloration of the insect can vary from brown to green, providing excellent camouflage in natural environments. Interestingly, when these animals are raised in the presence of lichen, they will often physically change to look like lichen themselves, although it is not always guaranteed. Adult females can reach lengths of up to 15 centimeters (6 inches), making them one of the larger stick insect species. Like other stick insects, the giant prickly stick insect is primarily nocturnal and spends its days motionless, relying on its camouflage to avoid detection. They are generally calm and gentle creatures that move slowly when active. These critters are herbivorous and can be fed a variety of leaves, including eucalyptus, bramble, rose, and oak leaves. This species is considered low maintenance and relatively simple to care for. They require a large, well ventilated mesh enclosure with a fresh source of leaves. Temperatures should be kept at around 20-25°C (68-77°F), with relative humidity levels of around 60% RH. Providing these insects with additional items such as twigs, branches, or corkbark, will allow them more surface area to climb around on. Overall, the giant prickly stick insect is a brilliant choice for invertebrate keepers due to its unusual appearance, docile demeanor, and low maintenance care requirements..
