One example of a fish that aestivates is the lungfish.
Aestivation is a state of reduced activity and metabolic rate that some animals use as a way to survive during periods of high temperatures and low water availability. Lungfish are found in tropical and subtropical regions where the water can evaporate during the dry season, leaving behind isolated pools with limited resources. In response, lungfish can aestivate by burrowing into the mud at the bottom of the pool, secreting a mucus cocoon around themselves, and slowing down their metabolism to survive for months without food or water until the rainy season returns.
Sharks, croakers, and catfish are not known to aestivate. Sharks are adapted to survive in a wide range of temperatures and environments, including cold and warm water. Croakers and catfish are freshwater fish that can tolerate a wide range of temperatures and water conditions, but they do not have the ability to aestivate.
