Mudskipper

Description:

They are completely amphibious fish, fish that can use their pectoral fins to walk on land.[2][3] Being amphibious, they are uniquely adapted to intertidal habitats, unlike most fish in such habitats which survive the retreat of the tide by hiding under wet seaweed or in tidal pools.[4] Mudskippers are quite active when out of water, feeding and interacting with one another, for example to defend their territories. They are found in tropical, subtropical and temperate regions, including the Indo-Pacific and the Atlantic coast of Africa.
