In a recent article Nagy and colleagues (2014) report on a fourth specimen of this snake collected during a field expedition to the Democratic Republic of the Congo in June–July 2012. The authors obtained the snake in Kinshasa, in proximity of the Congo River.
Ecologically, Helophis schoutedeni is a semi-aquatic snake as suggested by its dorsally-oriented nostrils, narrow triangular internasals, small eyes with round pupil and stout body. And, during a short period in captivity, the snake preferred to stay in water. Helophis is morphologically similarity to the genus Hydraethiops another poorly known aquatic snake from Africa.
The photos here are most like the first ones take of live specimen of this species.
