koala

Icónico marsupial del este y sureste de Australia, los koalas pesan hasta 15 kg y pasan hasta 22 horas diarias durmiendo para conservar energía de su dieta de hojas de eucalipto, baja en calorías. Altamente especializados para procesar los compuestos tóxicos del eucalipto que matarían a la mayoría de los demás mamíferos, poseen microbiomas intestinales únicamente adaptados para la desintoxicación. Clasificado como En Peligro en 2022, con poblaciones diezmadas por la enfermedad de clamidia, la deforestación y el cambio climático.
