Salamanderfish: Nature's Ultimate Survivors

The video explores the unique salamanderfish found in southwestern Australia, which survive in ephemeral pools by burrowing into the sand and entering a dormant state called estivation. These fish have adapted to extreme conditions, including acidic water and temperature fluctuations. However, climate change poses a threat to their habitat, raising concerns about their future. The video is supported by Brilliant, which offers courses in STEM topics.
