TED-Ed: The fish that walk on land | Noah R. Bressman

The video explores the fascinating world of amphibious fish, focusing on the walking catfish and its ability to survive on land. It discusses the spectrum of amphibious fish, from those that only venture onto land when necessary to those that thrive in both environments. The video highlights the unique adaptations these fish have developed, such as breathing through their stomachs or using true lungs. It also covers their survival strategies, like rolling in mud or creating mucus cocoons, and their navigation techniques using fins and taste buds. Despite the challenges, these fish gain new opportunities and resilience.
