The common eel has a round, elongated body and a continuous dorsal fin which joins with the ventral fin at the tail. The dorsal fin starts well down its back, near to the vent than the gills and the pectoral fin is rounded.
The catfish or wolf fish is a long bodied species with no pelvic fins. The dorsal and anal fins are long with the dorsal starting above the gill plate.
While the red bream has the basic bream family shape it is not as deep bodied as some and has a rounded head. It has large eyes and long pectoral fins.
The gilthead bream has the typical deep, flat profile bream shape. It has a distinct bump on the head above the gills. The front teeth are sharp and pointed whereas the others are flat for crushing.
The black bream is a deep bodied, fully scaled species with a relatively small head and spiny single dorsal fin. The back of bream is darkish blue-grey merging into silvery-grey on the sides.
The anglerfish is basically a broad flat head with a mouth and a tail. The rays of the first dorsal fin are spines and the second one has 11-12 rays.
The undulate ray has the typical kite shape with rounded tips to the wings and a shortish snout. The back and snout are covered with short spines.
The body of the thornback ray has the kite shape that is typical of the skates and rays. As its name suggests it has thorns on its upper surface particularly from the root of the tail down to the dorsal fins at its tip.
