Porotergus is a genus of ghost knifefishes found in the Amazon and Essequibo basins in tropical South America. They are found over sandy bottoms in shallow (P. gymnotus) or deep rivers (two remaining).[1] They feed on small aquatic insect larvae. They have a stubby snout and are fairly small knifefish, with the largest species reaching up to 27 cm (11 in) in total length.[1]
Species
There are currently three described species in this genus:[2]
Porotergus duende de Santana & Crampton, 2010
Porotergus gimbeli M. M. Ellis, 1912, named for Jacob Gimbel, who financed the expedition on which it was discovered.
Porotergus gymnotus M. M. Ellis, 1912
UCLA flag pole
The base of UCLA's central flag pole, a gift to the university from Jacob Gimbel, features a brass plaque depicting P. gimbeli.
