Mudskippers

Mudskippers (Periopthalmus koelreuteri), also known as mudhoppers, are small, maybe 3 inches in length at most.

Photographed in a mangrove swamp on the coastline, mudskippers exist along the edges of muddy puddles and lagoons within mangrove environments or other intertidal zones.

These creatures are adapted to survive in water and on land. They breathe through gills under water and breathe air on land through blood-rich membranes at the back of the mouth and throat.
