Well, the mudskipper certainly thinks so. This frog-eyed fish—which lives in coastal mangrove swamps of the Indian and Pacific Oceans—can survive on land when the tide goes out. While on land, mudskippers use their fins to move—in fact, some of the larger species can “skip” over the mud faster than you can walk! If necessary, mudskippers can also climb up the roots of mangrove trees.
