Dictyota dichotoma is a common brown alga with repeatedly forked, flat, olive-green to golden-brown fronds forming broad, fan-like thalli. It inhabits intertidal and shallow subtidal rocky shores of temperate to tropical seas worldwide. This photosynthetic macroalga anchors to rock via a holdfast and can reproduce both sexually and asexually.

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.
