koala

Icônico marsupial do leste e sudeste da Austrália, os coalas pesam até 15 kg e passam até 22 horas diárias dormindo para conservar energia de sua dieta de folhas de eucalipto, com baixo teor calórico. 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.
