corticeira

The cockspur coral tree (Erythrina crista-galli) is a striking deciduous tree in the family Fabaceae native to the warm-temperate and subtropical riverbanks, gallery forests, and seasonally flooded grasslands of South America, particularly in Argentina, Uruguay, Brazil, and Paraguay. It has been widely planted and naturalised worldwide in warm climates as an ornamental, chosen for its spectacular racemes of vivid scarlet, claw-shaped flowers — borne on thorny stems before or alongside the new leaves — that attract hummingbirds and other nectarivores. The species name crista-galli means cock's crest in Latin, describing the red comb-like flower shape. Growing to 5–10 metres, the tree develops a gnarled, spreading crown and thick, spongy bark. In Argentina, E. crista-galli is the national tree — known locally as ceibo — and the ceibo flower is the national flower, celebrated in art, literature, and folklore. The tree's hollow, water-filled stems and lightweight wood allow it to survive periodic flooding; in southern Brazil it is characteristic of the pantanal and riverine woodland ecosystems. Pods containing bright red seeds — toxic if ingested — split when mature. The bark and flowers have traditional medicinal uses in South American folk medicine. Erythrina crista-galli is classified as Least Concern by the IUCN given its wide native distribution and extensive cultivation globally.

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.
