Petrogale is a genus of marsupials commonly known as rock wallabies. Other synonyms for this genus include waalara, otogale, bennett's wallaby, black wallaroos, and yellow-footed rock wallabies. These animals are named for their ability to climb and live on rocky terrain, with strong legs and agile movements. They have thick fur coats to protect them in their rocky habitats and are known for their distinctive markings, including stripes and spots. Petrogale species are found throughout Australia, and their conservation status varies from the vulnerable black-flanked rock wallaby to the critically endangered brush-tailed rock wallaby. Despite their tough exterior, petrogale species face numerous threats, including habitat loss, predation by introduced predators, and disease.
