Common Poison-arrow Frog

<em>Oophaga histrionica</em>, the common poison arrow frog, is a small, brilliantly coloured dendrobatid frog in the family Dendrobatidae, endemic to the lowland and foothill rainforests of Colombia. Like other members of the genus Oophaga, it is aposematically coloured, displaying vivid patterns of red, yellow, black, and white that warn predators of its potent skin toxins, which are derived from the arthropods in its diet. The species is typically terrestrial and diurnal, inhabiting the leaf litter and low vegetation of humid tropical forests where males call to attract females and defend territories. Parental care is well developed, with females transporting tadpoles on their backs to water-filled bromeliads and subsequently feeding them with unfertilised trophic eggs. <em>Oophaga histrionica</em> is assessed as Critically Endangered on the IUCN Red List, reflecting severe population declines driven by extensive deforestation, agricultural expansion, and collection for the international pet trade within its restricted Colombian range. Biological traits such as average adult lifespan, precise body dimensions, and detailed dietary composition across its range remain poorly documented in the scientific literature. Conservation measures include habitat protection and captive breeding programmes.

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.
