The Lungfish survives prolonged droughts where its freshwater habitat dries up. It has evolved the ability to breath fresh air, secrete a mucous membrane to form a protective cocoon that helps it retain moitsture, and its fins are heavily modified to aid with land based locomotion. Lungfish are the closest relatives to tetrapods who likely evolved under similar conditions. https://education.nationalgeographic.org/resource/west-african-lungfish/ https://education.nationalgeographic.org/resource/west-afric...
