The Spined Loach (Cobitis taenia) is a relatively common species for the Danube's basin and the river Elbe.

The Spined Loach inhabits both streams and dead waters and it is a species which during daytime remains on the bottom of the water, hidden under the sandy substrate, and at night becomes active, in order to relieve its hunger.

This species feeds on a variety of invertebrates, but it also consumes detritus – a sort of material resulted from the crumbling of the rocks.

A Spined Loach's body is oblong. Around its mouth it has 3 pairs of small whiskers. This fish also has a suborbital spine.

The Spined Loach is a species with no importance for the industrial or the sportive fishing.
