Belonging to the Macropodidae family, wallabies are generally classified as any macropod that is smaller than a kangaroo. However, wallabies are not a separate genetic group, and the term instead covers a broad category of different species, such as the agile wallaby and the rock wallaby. History: Wallabies are fairly common and naturally occurring across Australia and New Guinea, and many species have been introduced to other regions like New Zealand. They are threatened by both humans and feral animals like dogs, but classifying wallabies as overarchingly vulnerable or not is challenging due to the wide range of known and differing species. Scientific Name: Family Macropodidae Characteristics: Due to the broadness of the term, wallabies can come in many different shapes and sizes, ranging from 18 to 72 inches tall. Size: 2.5 inches long and 1.5 inches tall, this wallaby toy model is roughly the size of a credit card stood upright.
