Range

Found in Australia. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Euglena gasterosteus is a freshwater euglenoid alga with a spindle-shaped, flexible cell body and chloroplasts enabling photosynthesis in well-lit aquatic environments. It inhabits ponds, ditches, and slow-moving freshwaters rich in organic matter. Like all euglenas, it can switch between autotrophic and heterotrophic nutrition and uses a flagellum for movement in the water column.

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.
