(Synodontis haugi)
Synodontis haugi, known as the black synodontis, is a species of upside-down catfish native to Gabon where it is found in the Ogowe River basin. It was first collected by M.E. Haug and described by French zoologist Jacques Pellegrin in 1906, based upon a holotype discovered in the Ogooué River, near Ngomo, Gabon. The specific name "huagi" is a tribute to the original collector of the species.
