s using chemoreceptors on its barbels. As they grow larger fish form a greater part of their diet. In the Mediterranean they spawn from late July up to September, the spawn and larvae are planktonic, settling to a benthic habit at 4–5 cm in length and becoming sexually mature when they are about a year old, c. 10 cm in length. They form large schools which are normally quite fast swimmers, occasionally stopping to feed. It is normally found at depths of 10–80m on continental or insular shelf regions. The maximum lifespan for fish caught off Turkey was found to be 5 years for males and six years for females.
