Ammodytes tobianus (Lesser sand eel)

The lesser sand eel or sand lance, Ammodytes tobianus, is a species of fish in the sand lance family Ammodytidae.

There are five common species of sandeel in Britain, but the only one of real importance to the fly rodder is the lesser sand eel (Ammodytes tobianus).

The great sand eel can be distinguished from the lesser sand eel because the origin of its long dorsal fin is located behind the level of the pectoral fin.
