Are there certain fish that can live without water?

Yes, for a period of time. The mangrove killfish spends several months of every year out of the water, living inside rotting branches and tree trunks. The 2-inch-(5-centimeter-) long fish normally lives in muddy pools and the flooded burrows of crabs in the mangrove swamps of Florida, Latin America, and the Caribbean. When their pools of water dry up, they temporarily alter their gills to retain water and nutrients, while they excrete nitrogen waste through their skin. These changes are reversed as soon as they return to the water. The mangrove killfish is not the only fish able to temporarily survive out of water. The walking catfish of Southeast Asia has gills that allow it to breathe in air and in water. The giant mudskippers of Southeast Asia breathe through their gills underwater and breathe air on land by absorbing oxygen through their skin and the back of the mouth and throat.
