Turko co-authored a recent study on the
mangrove rivulus
, a fish that leaps on land when its tropical waters get too warm. (Related: “To Cool Off, This Fish Leaves the Water.”) Fish use gills to take in oxygen from the water. But many fish, like the mangrove rivulus, have adaptations that let them breathe air.

Are dolphins fish?
Dolphins are mammals, not fish
.
Unlike fish, who breathe through gills, dolphins breathe air using lungs. Dolphins must make frequent trips to the surface of the water to catch a breath. The blowhole on top of a dolphin’s head acts as a “nose,” making it easy for the dolphin to surface for air.
Are there any animals that can breathe on land and water?
Amphibians are vertebrates (animals with backbones) which are able, when adult, to live both in water and on land

How long fish can survive without oxygen?
