common antlers sponge

<em>Axinella polypoides</em>, commonly known as the Common Antlers Sponge, is a marine sponge in the family Axinellidae. This species has not been formally evaluated by the IUCN and has been recorded in waters off Norway, among other European marine environments. The Common Antlers Sponge is an erect, branching sponge that typically forms irregularly branched, tree- or antler-like colonies in yellow to orange coloration, which are visually distinctive on the rocky substrates of the Mediterranean Sea and the northeastern Atlantic Ocean. It typically grows attached to hard substrates such as rocks and corals in subtidal zones, often in areas with moderate to strong water currents that deliver particulate food. As a filter feeder, it draws water through its porous body to extract organic particles and microorganisms. This sponge can reach substantial sizes and is often found in deeper, clear-water habitats. 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.
