Paraulopus Explained
Paraulopus is the only genus in the family Paraulopidae, a family of grinners in the order Aulopiformes. They are commonly known as cucumberfishes, but locally some other Teleostei are also known by that name. They were considered in the Chlorophthalmidae or greeneye family until 2001.
The fishes tend to be slender and cylindrical, with large eyes and a large terminal mouth with only slightly protruding lower jaw.[1]
The earliest known fossil evidence of cucumberfishes are otoliths from the Aptian and Albian of Spain, France, and Texas. It remains uncertain whether these otoliths actually belong to Paraulopus itself or to an extinct fossil paraulopid genus.[2]
