Mogurnda adspersa
''Mogurnda adspersa'' (commonly known as the southern purple-spotted gudgeon) is a species of endangered gudgeon that is endemic to southeastern Australia. The fish is brown, although the shade becomes lighter near its abdomen. Spots of various colors occur on its sides. After a dramatic population decline in the late 20th century, the fish was thought to be extinct, but it was rediscovered in 2002. The government of Australia is currently taking measures to increase the fish's numbers.
