Conger eel, sea eel. The crustaceans and fish which form its diet contribute to its own good flavour. It is usually sold in steaks. It has few bones and good firm flesh with excellent flavour. The neck end has a better ratio of flesh to bone so is better for cooking as steaks, whereas the tail end, which is bonier, makes a useful addition to soups and stocks.

Grey mullet, the commonest and largest of the grey mullet (US: striped mullet) family. It is a silver, shoal-living fish pointed with dark grey which feeds on seaweed and plankton near the muddy bottom in estuaries and coastal waters. This can effect its flavour. However, a good grey mullet, caught in clean water, is round-bodied and has creamy white flesh and good flavour with good keeping capabilities. It must be thoroughly scaled before eating. Varieties are found all over the world. The roe is used for taramasalata, botargo, boutargue.

Red mullet or surmullet. A high quality fish of a different family from the other (grey) mullets, and which has a far better flavour and lean, firm flesh. Its liver is highly prized. Do not confuse it with gurnard, which has a slightly paler colour. This fish may vary from pinkish-reddish crimson to rosy pink in colour with golden streaks and two long barbels on the chin. Mullus barbatus is the smaller of the two and is of not quite such good quality. Mullus surmuletus is more properly known as surmullet and is larger.
