Walking fish, sometimes called ambulatory fish, is a general term that refers to fish that are able to travel over land for extended periods of time. Mudskipper is one of them.But how this fascinating creature can live out of water? Mudskippers are able to extract oxygen from different parts of their body. Recent research has found mudskippers don’t use their gills for oxygen exchange, but use their skin for a large part of their oxygen processing .Mudskippers are quite active when out of water, feeding and interacting with one another. They are found in tropical, subtropical and temperate regions, including the Indo-Pacific and the Atlantic coast of Africa.
