Raitt's Sand Eel,  Ammodytes marinus

The Raitt's sand eel, sometimes known as the lesser sand eel, is a small, elongated fish that is usually about 20 cm long. The maximum length reported for this species of sand eel is 25 cm. They are silver all over with darker scales on their dorsal side. Raitt's sand eels have a short tail fin that is deeply forked. They have a long and low dorsal fin that is twice as long as the tail fin and runs along almost the entire body. The scales on their underside are arranged randomly instead of in a distinct pattern as in many other fish. The Raitt's sand eel has a pointed jaw where the lower jaw projects further than the upper jaw. Image: © Teddydolstra (iNaturalist).
