English: Mudskippers are members of the subfamily Oxudercinae (Periophthalmini), within the family Gobiidae (Gobies). They are completely amphibious fish, 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. Mudskippers are quite active when out of water, feeding and interacting with one another, for example to defend their territories.
