Mudskippers are members of the subfamily Oxudercinae. They are an amphibious fish, meaning they can survive on either land or in the water. Though the tend to stay in intertidal habitats, they have been spotted walking with their pectoral fins in other locations. When not in the water, they are generally feeding or interacting with others of their species, such as defending their territory. They are found in tropical and sub-tropical regions, including the Indo-Pacific and Atlantice coasts of Asia. Their common nickname, mudskipper, comes from the way they move around in their natural habitat, which is by "skipping" or jumping up in the air.
Red Mangrove Crab
The Red Mangrove Crab is an important species in almost every mangrove environment around the world. They are so necessary to the growth of a mangrove forest because they recycle most of the energy by eating the dead leaves of the mangrove trees. Another reason why they are useful to a mangrove forest is that their feces is the base of the coprophagous food chain contributing to the mangrove secondary production.The red mangrove crab has two main ways of defending itself: burrowing in the ground to hide from other predators and climbing up a tree to take a defensive stand from its branches.
The fiddler crab, also known as the calling crab or Uca, is another common species of carb in the mangrove forests. At only about 2 inches across, this species of crab has become very developed from a survival standpoint. If they lose a leg or arm during their growth cycle, they merely grow it back during the next molt. Because of this, they are able to survive long enough to reproduce and continue on as a species. If the large fiddle claw is lost, it will be grown again on the opposite side next cycle. During they molt, because their new shell is soft and they are vulnerable, fiddler crabs hide in the crevices of the mangrove trees until they have regrown all limbs and their new shell has hardened. They are found in sea beaches,brackish inter0tidal mud flats, lagoons, swamps, and mangrove forests.
