The Northern Iberian spined loach (Cobitis calderoni) is a freshwater fish of the family Cobitidae that grows up to 10 cm.
Description
The northern Iberian spined loach, called lamprehuela in Spain, is a slender loach of the family Cobitidae reaching about 10 cm. The yellow-brown body bears a row of dark spots along the flank; barbels surround the inferior mouth, and beneath each eye sits a small, erectile spine, characteristic of the true spined loaches. The species is endemic to the north of the Iberian Peninsula and adapted to fast-flowing water: it lives on gravel and sand bottoms of clear, fast rivers. By day it often lies half-buried; mainly at night it sifts insect larvae, small crustaceans and worms from the bottom. In spring it spawns among gravel and sand. Through water pollution, water abstraction and river works it has declined and is assessed as Vulnerable (VU).
