Scientific name: Macropus robustus (ssp robustus and ssp erubescens) Common name: Wallaroo / Euro The Wallaroo or Euro as a mature male can weigh in around 40 kg the female 20kg. Euros are stockier than the Greys and Reds,and tend to be independent with a sometimes aggressive nature. The coat colour varies from a dark, rich red in the males to varying shades of grey in females. The coat has a hair-like texture and in some individuals can be very long. (When males are sterilised they lose their rich, red coat colour and assume the colouring of the females.) Euros have a naked, leathery nose, which is also evident in furless joeys. The characteristic “cch cch” sound of the wallaroo joey is a means of recognition for mother and joey.
