a fish out of water
How can mudskippers live out of water ? Mudskippers are able to extract oxygen from different parts of their body . recent research has found mudskippers don't use their gills for oxygen exchange, but use their skin for a large part of their oxygen processing . They use their gill filaments to exchange ammonia .Mudskippers must always keep their mouths and skin moist, since the oxygen needs to diffuse with water before they can absorb it . They are completely amphibious fish, uniquely adapted to inter tidal habitats, unlike most fish in such habitats, which survive the retreat of the tide by hiding under wet seaweed or in tidal pools.Mudskippers are quite active when out of water, feeding and interacting with one another, for example to defend their territories.

Mudskippers need to live in habitats that are hot and humid in order to breathe , where air and water temperature range from 75 to 86 F and humidity from 60 to 80 percent .Mudskippers are only active when temperatures are above 55 F . Mudskippers live in brackish to normal seawater depending on the species .It grows to a length of about 6 in (15 cm) and is a carnivorous opportunist feeder. Mudskippers dig deep burrows to escape predators and raise their young . they maintain a air pocket in their burrows to breathe .
During the mating season, the male's colors become more intense and the male becomes much more active . Males do what appear to be pushups, leap and flip in the air and even stand on their tales - all to attract female mudskippers. the male becomes more aggressive torward other males with biting and raising its dorsal fins . If the female is attracted to the male, she does her own mating ritual with distinctive movements . She then goes into the male's burrow where she lays her eggs in a special part of the burrow the male builds her . The males then fertilizes the eggs and takes over responsibility for the eggs. to oxygenate the eggs, the male swallows air on the surface and releases it in the mudskipper baby burrow .
