Common blowfly

The common blowfly (<em>Calliphora grahami</em>) is a fly species found across the United States, typically inhabiting all terrestrial and freshwater environments. As a member of the family Calliphoridae, this species often plays an important ecological role as a decomposer and pollinator across its range. The common blowfly is classified as Least Concern on the IUCN Red List, indicating a stable population with no immediate threat of extinction. Its diet includes decaying organic matter, making it a significant contributor to nutrient cycling in its native habitats. The species is commonly associated with a wide variety of terrestrial ecosystems, from open grasslands to forested areas, and is often found near human settlements. Biological traits of this species remain poorly documented in the scientific literature.

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.
