ISLAMABAD - Scientists have made a depressing discovery – the first marine fish of modern times has been declared extinct. The smooth handfish has officially been wiped from the southeastern Australian waters due to habitat decline, pollution and destructive fishing practices. The bottom-dweller was one of 14 species of handfish, which use highly modified pectoral fins to ‘walk’ along the seabed. Smooth handfish were first discovered in the early 1800s during a scientific exploration, but the only thing left of the species is a preserved specimen collected during that dive.
