Altamente especializados para processar os compostos tóxicos do eucalipto que matariam a maioria dos outros mamíferos, possuem microbiomas intestinais unicamente adaptados para a destoxificação. Classificado como Em Perigo em 2022, com populações dizimadas pela doença de clamídia, desmatamento e mudanças climáticas.
