The article discusses how fish survive through extreme weather conditions, with the example of African lungfish, which can survive for up to 3 or 4 years outside of water without changing their behavior over millions of years. The species, often referred to as "living fossils," enter a state of estivation to survive the hot and dry months, which may last several years. Once reintroduced to water, they resume normal activity and return to their bodies. Unlike mammals, which store food and have plenty of fur to keep them warm in winter, fish have different methods of coping during diverse weather events.
