1. Tree Kangaroos: Several different species of tree kangaroos closely resemble regular kangaroos. They share various anatomical and physiological traits, but tree kangaroos are adapted for an arboreal lifestyle.
2. Wallabies: Wallabies are smaller hopping marsupials closely related to kangaroos. Some wallabies are similar in appearance to smaller kangaroo species, with some exceptions in body size and specific adaptations.
3. Quokkas: Quokkas are marsupials resembling miniature kangaroos. Native to Western Australia, these small and adorable marsupials have gained online fame for their friendly expressions and photogenic behaviors.
4. Pademelons: Pademelons are small to medium-sized marsupials that bear similarities to kangaroos. Several pademelon species inhabit various forests and shrublands of Australia and nearby islands.
It's important to note that all of these marsupials still have variations and adaptations specific to their unique ecological niches. They may differ in size, tail shape, fur color, habitat preferences, and specific physiological attributes from the stereotypical representation of kangaroos. Nonetheless, their marsupial traits, general morphology, and hopping abilities often link them to the larger taxonomic group of kangaroos.
