Stone loach
The stone loach (''Barbatula barbatula'') is a species of fresh water ray-finned fish in the Balitoridae family. It is one of seventeen species in the genus ''Barbatula''.
It is found in Baltic states, Eastern Europe, Austria, Belgium, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Hungary, Ireland, Italy, Liechtenstein, Luxembourg, Moldova, the Netherlands, Poland, Romania, Serbia and Montenegro, Slovakia, Spain, Sweden, Switzerland, and the United Kingdom.
Stone loaches live amongst the gravel and stones of fast flowing water where they can search for food. The most distinctive feature of this 14 cm fish is the presence of barbels around the bottom jaw, which they use to detect their invertebrate prey. The body is a mixture of brown, green and yellow.
==Description==
The stone loach is a small, slender bottom-dwelling fish growing to a length of about . Its eyes are situated high on its head and it has three pairs of short barbels on its lower jaw below its mouth. It has a rounded body that is not much laterally flattened and is a little less deep in the body than the spined loach (''Cobitis taenia'') and lacks that fish's spines beneath the eye. It has rounded dorsal and caudal fins with their tips slightly notched, but the spined loach has even more rounded fins. The general colour of this fish is yellowish-brown with blotches and vertical bands of darker colour. An indistinct dark line runs from the snout to the eye. The fins are brownish with faint dark banding.〔(【引用サイトリンク】title=Stone loach: ''Barbatula barbatula'' (L.) )〕
