Dalophis imberbis (Delaroche, 1809)

Two Armless snake eels, Ophichthidae ( Fig. 2F ), were observed beached by S. Brunelle on 3 Mar. 2018 ( Brunelle et al., 2018). They were found dead in a rock pool on La Baleine beach in Sète ( Hérault ), in the Gulf of Lion ( Mediterranean Sea , France), at 43.3876°N, 3.6493°E. The individuals were roughly 40 cm TL. The presence of these beached individuals could have been caused by the storm of 2 Mar. 2018. The species has also occasionally been observed by S. Le Bris during night scuba dives, in 2018, in the outer harbour of Les Goudes , Marseille (Bouches-du-Rhône, France, Mediterranean Sea), at 43.2165°N, 5.3455°E, at 4-5 m depth on sand bottom. This species is uncommonly observed because of its cryptic habitat and nocturnal activity .
