these fish have adapted to life both in and out of the water. Here are eight fascinating species:
MudskippersThese small, amphibious fish are found in muddy tidal flats. They use their modified pectoral fins to "walk" on land and even climb trees.
Walking CatfishNative to Southeast Asia, this fish can use its pectoral and pelvic fins to "walk" across land. It's known for its ability to survive out of water for extended periods.
Climbing Perch This fish has a unique labyrinth organ that allows it to breathe air. It can climb trees and even travel across land to find new bodies of water.
Epaulette SharkA small shark found in Australia, the epaulette shark can "walk" on the ocean floor using its modified pectoral fins. It can also survive out of water for short periods.
Mangrove RivulusThis tiny fish lives in the mangrove swamps of South America. It can breathe through its skin and gills, allowing it to survive out of water for extended periods.
GurnardsThese fish have fleshy appendages on their pectoral fins that they use to "walk" along the ocean floor. While they don't venture onto land, their ability to move on the seabed is impressive.
BatfishThese odd-looking fish have modified pectoral fins that resemble legs. They use these fins to "walk" along the ocean floor, searching for food.
Lungfish These fish have lungs that allow them to breathe air. They can survive out of water for extended periods, burrowing into mud to stay moist.
