Mudskippers are a type of fish. They are part of a fish family known as the gobies. They are amphibious fish: they can use their pectoral fins to "walk" on land. They are adapted to intertidalhabitats. These are places where the tide of the ocean comes in and out. Most fish that live in these habitats hide under wet seaweed or in tidal pools to stay moist or wet when the tide goes out. Mudskippers are active when they are out of the water. They eat and interact with each other. They defend their territories.
