A new fish species belonging to the Phallostethidae family was recently discovered in Vietnam’s Mekong Delta.

Found in the waters of Southeast Asia, these fish are characterized as unusual due to their penises being positioned on their heads.

Phallostethus cuulong, as researchers call it, was reportedly long known about by the people residing in the Mekong Delta area, but the fish was just recently discovered by scientists.

“We have scientifically identified a new penis-head fish in Vietnam,” researcher Tran Dac Dinh from Can Tho University said.
