About Periophthalmus argentilineatus Valenciennes, 1837
Periophthalmus argentilineatus, commonly known as the barred mudskipper or silverlined mudskipper, is a species of mudskipper. It is native to marine, fresh, and brackish waters ranging from the African coast of the Indian Ocean to the Marianas and Samoa in the western Pacific Ocean, and from the Ryukyus south to Australia. This species lives in mangrove forests and nipa palm stands, and is capable of crossing mud surfaces while out of water. It can grow up to 19 centimetres (7.5 inches) in total length, and is available in the aquarium trade. Known parasites of the barred mudskipper include Acanthocephalan larvae and the small Opecoelid Digenean *Opegaster ouemoensis*, an intestinal parasite first described from barred mudskippers collected in New Caledonia.
