The European conger (Conger conger) is a species of conger of the family Congridae. It is the heaviest eel in the world and native to the northeast Atlantic, including the Mediterranean Sea.
European congers have an average adult length of 1.5 m (5 ft), a maximum known length of around 2.133 m (7 ft) (possibly up to 3 metres (9 ft 10 in) for the largest specimens), [2] and maximum weight of roughly 72 kg (159 lb), [3] making them the largest eels in the world by weight. They can be rivaled or marginally exceeded in length by the largest species of moray eel but these tend to be slenderer and thus weigh less than the larger congers. [4] Average specimens caught will weigh only 2.5 to 25 kg (5.5 to 55.1 lb). [5] [6] Females, with an average length at sexual maturity of 2 m (6 ft 7 in), are much larger than males, with an average length at sexual maturity of 1.2 m (3 ft 11 in). [7]
The body is very long, anguilliform, without scales. The colour is usually grey, but can also be blackish. The belly is white. A row of small white spots is aligned along the lateral line. The head is almost conical, and slightly depressed. The snout is rounded and prominent, with lateral olfactory holes. The large gill openings are in the lateral position. The conical teeth are arranged in rows on the jaws. The dorsal and anal fins are confluent with the caudal fin. Pectoral fins are present, while ventral fins are absent.
Conger eels have habits similar to moray eels. They usually live amongst rocks in holes, or "eel pits", sometimes in one hole together with moray eels. They come out from their holes at night to hunt. These nocturnal predators mainly feed on fish, cephalopods, and crustaceans, although they are thought to scavenge on dead and rotting fish, as well as actively hunt live fish. [8] Congers can be aggressive to humans, and large specimens can pose a danger to divers. [9]
This species can be found in the eastern Atlantic from Norway and Iceland to Senegal, and also in the Mediterranean and Black Sea [10] at 0–500 m of depth, although they may reach depths of 3600 m during their migrations. [11] It is sometimes seen in very shallow water by the shore, but can also go down to 1,170 m (3,840 ft). It is usually present on rough, rocky, broken ground, close to the coast when young, moving to deeper waters when adult.
When conger eels are between 5 and 15 years old, their bodies undergo a transformation, with the reproductive organs of both males and females increasing in size and the skeleton reducing in mass and the teeth falling out. [12] Females appear to increase in weight and size more than the males.[ citation needed ] Conger eels then make migrations to spawning areas in the Mediterranean and the Atlantic, "although the existence of one or multiple spawning grounds for the species remains uncertain". [13] The female conger eels produce several million eggs, and both the females and males die after spawning. Once hatched, the larval conger eels begin to swim back to shallower waters, where they live until they reach maturity. They then migrate to repeat the cycle. [14]
Mycteroperca bonaci, the black grouper, black rockfish or marbled rockfish, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. Other fish are sometimes called the black grouper including the similar gag grouper, the misty grouper, and the warsaw grouper. This species is found in the western Atlantic Ocean from the northeastern United States to Brazil.
Conger is a genus of marine congrid eels. It includes some of the largest types of eels, ranging up to 2 m (6 ft) or more in length, in the case of the European conger. Large congers have often been observed by divers during the day in parts of the Mediterranean Sea, and both European and American congers are sometimes caught by fishermen along the European and North American Atlantic coasts.
The common ling, also known as the white ling or simply the ling, is a large member of the family Lotidae, a group of cod-like fishes. It resembles the related rocklings, but it is much larger and has a single barbel. This species is unrelated to the pink ling, Genypterus blacodes, from the Southern Hemisphere. The common ling is found in the northern Atlantic, mainly off Europe, and into the Mediterranean Basin. It is an important quarry species for fisheries, especially in the northeastern Atlantic, although some doubts exist as to the sustainability of the fisheries. As an edible species, it is eaten fresh, frozen, or dried, but also preserved in lye, while the roe is a delicacy in Spain.
The white grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. The white grouper is found in the subtropical eastern Atlantic Ocean and the southern Mediterranean Sea.
The Atlantic sawtail catshark is a little-known species of deepwater catshark, belonging to the family Pentanchidae, found in a small area of the northeastern Atlantic Ocean, centered on the Strait of Gibraltar and the Alborán Sea. It is found on or close to the bottom over the continental slope, mostly at depths of 400–600 m (1,300–2,000 ft). This shark closely resembles, and was once thought to be the same species as, the blackmouth catshark (G. melastomus); both are slender with a series of dark saddles and blotches along the back and tail, and a prominent crest of enlarged dermal denticles along the dorsal edge of the caudal fin. It differs subtly from G. melastomus in characters including snout length, caudal peduncle depth, and the color of the furrows at the corner of its mouth.
The Mediterranean moray, also known as Roman eel, is a species of fish in the moray eel family. It has a long eel-like body and is found in the eastern Atlantic Ocean and Mediterranean Sea. Its bite can be dangerous to humans.
The greater amberjack, also known as the allied kingfish, great amberfish, greater yellowtail, jenny lind, Sea donkey, purplish amberjack, reef donkey, rock salmon, sailors choice, yellowtail, and yellow trevally, is a species of predatory ray-finned fish in the family Carangidae, the jacks and pompanos. It is found in temperate, subtropical, and tropical seas around the world. It is a popular quarry species for recreational fisheries and is important in commercial fisheries. It is the largest species in the family Carangidae.
The tub gurnard, also known as the sapphirine gurnard, tube-fish, tubfish or yellow gurnard, is a species of marine ray-finned fish belonging to the family Triglidae, the gurnards and sea robins. It is found in the eastern Atlantic Ocean. It is exploited by commercial fisheries as a food fish.

The European pilchard is a species of ray-finned fish in the monotypic genus Sardina. The young of the species are among the many fish that are sometimes called sardines. This common species is found in the northeast Atlantic, the Mediterranean, and the Black Sea at depths of 10–100 m (33–328 ft). It reaches up to 27.5 cm (10.8 in) in length and mostly feeds on planktonic crustaceans. This schooling species is a batch spawner where each female lays 50,000–60,000 eggs.
Merluccius merluccius, the European hake, is a merluccid hake of the genus Merluccius. Other vernacular names include Cornish salmon and herring hake. It is a predatory species, which was often netted alongside one of its favoured prey, the Atlantic herring, hence the latter common name. It is found in the eastern Atlantic from Norway and Iceland south to Mauritania and into the Mediterranean Sea. It is an important species in European fisheries and is heavily exploited, with some populations being fished unsustainably.
The curled octopus, also known as the horned octopus, lesser octopus or northern octopus, is a species of cephalopod found in the northeast Atlantic, ranging from Norway to the Mediterranean, including the British Isles. The total length of an adult is around 50 cm, but their arms are often tightly curled. It immobilises and eats large crustaceans by drilling a hole through their shell. It is mainly by-catch in commercial fisheries of the north eastern Atlantic and Mediterranean, where the common octopus is the preferred species.
