Nínox de la Christmas

The Christmas Island boobook (Ninox natalis) is a small owl in the family Strigidae, endemic to Christmas Island, an Australian territory located in the Indian Ocean approximately 360 kilometers south of Java, Indonesia. It is one of a suite of highly distinctive endemic vertebrates found only on Christmas Island, reflecting the island's long isolation from mainland Australia and Southeast Asia. The species belongs to the boobook owl group, which is distributed across Australasia and the broader Indo-Pacific region. As a small predatory owl, the Christmas Island boobook feeds primarily on insects and small vertebrates, hunting at night in the dense tropical forest that covers much of the island. The remaining rainforest on Christmas Island provides critical habitat for this species. Conservation concerns for the Christmas Island boobook include invasive species, particularly the invasive yellow crazy ant (Anoplolepis gracilipes), which has devastated seabird colonies and dramatically altered forest structure and invertebrate communities on the island. Habitat degradation from phosphate mining activities has also affected parts of the island. The species has a small total population restricted entirely to Christmas Island and warrants ongoing monitoring and targeted conservation management.

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.
