Red-eyed Tree Frogs: Adaptive Embryo Behavior

The video discusses the red-eyed tree frogs, focusing on their breeding habits and the threats their eggs face. It highlights the adaptive behavior of embryos, which can hatch early in response to threats like predators, fungus, or suffocation. The embryos use vibrations to assess risks, particularly during snake attacks, and can distinguish between dangerous and benign vibrations. They also respond to suffocation by reorienting themselves to access oxygen. This adaptive behavior enhances their survival, opening up new research questions about embryo behavior.
