Walking Catfish and Their Unique Abilities

The video explores the unique adaptations of walking catfish, which can survive on land for up to 18 hours by using lung-like organs and following the scent of water. A study revealed that these fish use their sense of taste, rather than smell, to navigate towards water, as their bodies are covered in taste buds. The research suggests that walking catfish might 'sniff' with their lungs, although this is yet to be confirmed. Understanding their navigation could help manage invasive populations and provide insights into their evolution. The episode is supported by Brilliant, which offers courses in science and technology.
