Eastern tropical Atlantic Ocean - List of fishes

The Mediterranean parrotfish is a rare representative of the Scaridae in temperate zones. It is native to the warm waters of the south and east Mediterranean. It feeds mainly on algae and inhabits rocky areas up to a depth of 30 meters.

The scalloped hammerhead shark, a semi-oceanic hammerhead, is found in tropical and temperate waters worldwide. This species is easily recognizable by its curved flat head and black tips on the pectoral fins. These sharks feed on fish, cephalopods, and crustaceans, taking advantage of their flat head to make tight turns while hunting. Although potentially dangerous and aggressive towards intruders, attacks on humans are rare. Conversely, despite its wide distribution, this species is threatened with extinction.

Its shape and color helps it hide perfectly among the underwater plants. There are similarities in the way it reproduces compared to seahorses. The male has no pocket, but it carries egg rows glued to a ventral furrow.

It is one of the most colorful Mediterranean fish. The female has a black spot on the dorsal fin. The stain will disappear and its color becomes more vivid when it will change sex (hermaphroditism protogynous). It is more abundant in the northern Mediterranean.
