The cockle or donax trunculus lives in large colonies near the seagrass beds of Posidonia. It prefers sandy seabeds and depths of more than ten metres. It buries itself a few centimetres below the sandbed where it can eat and at the same time escape predators. Cockles are much sought after in the market and thus their fishing is carried out with the use of intense dredgers. The autumn season is the most conducive for catching cockles but now you can find them in supermarkets all year.
