Deltentosteus collonianus (Risso, 1820)

Three Toothed gobies, Gobiidae ( Fig. 7 A-C), were observed and photographed in 2019 by S. Le Bris, L. Bérenger and T. Menut while scuba diving on 15, 19 and

27 Feb in the Callelongue Creek and in the Saména Creek in Marseille (43.2104°N, 5.3506°E; 43.2112°N, 5.3513°E; and 43.2289°N, 5.3481°E, respectively, Mediterranean Sea) at 13-20 m depth. The individuals, ca. 6-7 cm TL, were observed lying on or swimming above fine sands ( Bérenger et al., 2019b; Le Bris et al., 2019b, 2019c; Menut et al., 2020). This poorly known species is uncommonly recorded by underwater observers.
