Gambia: Atlantic Mudskippers
The brackish mangrove estuaries of the Gambia River are home to Atlantic mudskipper (Periophthalmus barbarus). it is a fascinating fish known for its unique adaptations and behaviors. Unlike most fish, Atlantic mudskippers can live both in water and on land. They have specially adapted pectoral fins that allow them to “walk” on land. Mudskippers can breathe through their skin and the lining of their mouth and throat, provided they stay moist. They also have modified gills that retain water, allowing them to breathe air when on land. They have protruding, movable eyes that provide a wide field of vision, which is crucial for spotting predators and prey both in and out of the water. Male mudskippers are highly territorial. Mudskippers construct complex burrows in the mud, which can have multiple chambers and entrances. During the breeding season, males perform elaborate displays to attract females, including jumping and “dancing” on the mud.
