Periophthalmus gracilis
Known for their protruding eyes found on the very top of their flat head. Their most noticeable feature however is their side pectoral fins that are located more forward and under their elongated body. These fins function similarly to legs in that they allow the mudskipper to move from place to place. Although having the typical appearance of any other fish, these forward fins allow the mudskipper to “skip” across muddy surfaces and even give them the ability to climb trees and low branches. Because of these fins, mudskippers have also been found to be able to leap distances of up to two feet.
Mangrove swamp
Mudskippers have the ability to breathe through their skin and the lining of their mouth (the mucosa) and throat (the pharynx); this is only possible when the mudskippers are wet, limiting them to humid habitats and requiring that they keep themselves moist.
