Surmullet The surmullet has a spindly body, thickest directly behind the head, which tapers from head to tail. It has two dorsal fins, two side fins near gills and one abdominal next to tail. Its tail is yellowish, of regular shape and consists of two equally large fins. In the middle of the tail there is a notch. The surmullet has a red-brownish back with longitudinal darker red and brown stripes across the waist and thinner beneath yellowish lateral stripes and white belly. The chin has two elongated gropes with purpose is to dig in the sand looking for food. It can grow up to 1.5 kg, 50 cm in length and get 10 years of age but mullets as old are rare. With its tentacle mullet digs worms, crabs and small fish buried deeper in the sand. In winter, the surmullet goes deeper and in summer comes to the shallows. They move in flocks of several individuals.
