koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

Ramalina canariensis is a fruticose, strap-like lichen with pale grey-green, flattened lobes found in coastal and island habitats. It inhabits humid laurel forests and coastal fog zones of the Canary Islands and Macaronesian archipelago. This lichen obtains energy through its photosynthetic algal partner and is sensitive to habitat changes from deforestation and climate shifts.
