common blow flie

The common blow fly (<em>Calliphora vicina</em>) is a large, metallic-blue fly belonging to the family Calliphoridae. It is classified as Least Concern on the IUCN Red List and has been recorded across terrestrial and freshwater habitats in Africa, including South Africa, as well as across five European countries and the United States. <em>Calliphora vicina</em> is one of the most familiar blow fly species in temperate regions, often found around human settlements, carrion, and organic waste. It plays an important ecological role as an early colonizer of decomposing animal matter, and its predictable developmental stages make it a key species in forensic entomology for estimating post-mortem intervals. Adults typically feed on nectar, pollen, and decaying matter, while larvae develop in carrion or, occasionally, in wounds. The species is cold-tolerant and often active during cool weather when other blow flies are less abundant. Biological traits of this species remain poorly documented in the scientific literature.

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.
