Fish Lives for 66 Days Out of Water
The mangrove killifish (Kryptolebias marmoratus) is a tropical fish native to the coast from Florida to Brazil. The fish is able to survive out of water by breathing and excreting through their skin.
The fish is naturally found in brackish water environments, living in shallow ditches, crab burrows and even discarded beer cans. When their habitat is in danger of drying out, the fish takes refuge in moist environments such as logs.
During this time, the fish’s gills are temporarily altered to preserve water and nutrients. Gas exchange, as well as waste excretion occurs through the skin.These changes are reversed once the fish re-enters water.
In laboratory tests, the fish was found to be able to survive for 66 days without water. This is unique in that the fish is able to remain metabolically active throughout this period unlike the lungfish, which enters a dormancy state in the absence of water.
