In some areas of the world, the mudfish is on the endangered species list. This is a result of diminishing wetlands and swamps, which are the animalâs natural habitat. Most of the endangered mudfish are located in New Zealand and Australia, but they can also be found in other parts of the world.
One of the first four-legged creatures that walked on land moved like a fish known as a mudskipper, a study shows - dragging itself along on its forelimbs like crutches. The creature lived in floodplains on what is now Greenland during a period known geologically as the Devonian period - about 360 to 410 million years ago.
