The small snadeels, Ammodytes tobianus L., were collected (130 specimes) in June 1995 from the Polish bays of the Baltic Sea. Morphology of this species is poorly known. The age of fish examined ranged from 1+ to 4+, (age 2+ was dominant). The most abundant size group was the 13.0-13.99 cm length class. The coefficients of variation in the meristic characters were relatively low. The vertebral count and the number of plicae were the most stable characters in the sample studied, while the anal- and pectoral fin ray counts proved to be the most variable ones. Meristic characters can be described by the formula: D (47-49) 50-55, P (10) 11-12 (13), A (24, 25) 26-30 (31), sp.br. (21) 22-27 (28), vt. 61-67 (68). The morphometric relations showed a tendency to allometry, only the postdorsal and postorbital distances showed almost the isometric pattern of growth
