They will leap into the air to impress females and if the male succeeds in winning a female over, the male mudskipper watches over their eggs in his underground den.

However, rising temperatures and sea level due to climate change are allowing mangroves to expand their ranges farther away from the equator and encroach on temperate wetlands, like salt marshes. /StructParents 4 For swimming species, not only are the roots a great place for ample food, they are also a great hideout to avoid predators. However, because distinguishing a mangrove species is based upon physical and ecological traits rather than family lineage, scientists often differ in what they consider to be a true mangrove. /Border [0 0 0] Transfers of matter into and out of the physical environment occur at every level. . Initially, governments were ill-equipped to regulate this type of farming, and farmers were unaware of the destruction they were causing. Riverine mangrove forests are within river floodplains by the coast and are heavily influenced by the changing seasons.
