Greater amberjacks, Seriola dumerili, are the largest of the jacks and is also found in the Mediterranean. They usually have dark stripes extending from nose to in front of their dorsal fins. They have no scutes and soft dorsal bases less than twice the length of the anal fin bases. They are usually 18 kg or less, and are found associated with rocky reefs, debris, and wrecks, typically in 20 to 75 m.
Barracuda (Sphyraena sphyraena), tapering, compact body, laterally compressed. Long head with pointed nose and a prominent lower jaw. The two dorsal fins are quite seperate. Blueish-grey topside with numerous dark bands on the sides. Lives in open water from the surface down to 100 meters. Maximum size 165 cm.
The common name blenny is ambiguous at best, as it has been applied to several families of perciform marine, brackish and some freshwater fishes all sharing similar morphology (shape) and behaviour. There are six families considered "true blennies", all grouped together under the suborder Blennioidei; its members are referred to as blennioids. There are approximately 833 species in 130 genera within the suborder.
Bream is a general term for a number of species of freshwater and marine fish belonging to a variety of genera including: Abramis (e.g. A. brama, the carp bream); Acanthopagrus; Argyrops; Blicca; Brama; Etelis; Lepomis; Gymnocranius; Lethrinus; Nemipterus; Rhabdosargus and Scolopsis. Although species from all of these genera are called "bream", the term does not imply a degree of relatedness between these species. Fish termed "bream" tend to be narrow, deep bodied species. The name is a derivation of the Middle English word breme, of Old French origin. The term sea bream is sometimes used for porgies (family Sparidae) or pomfrets (family Bramidae).
Cardinalfishes are a family, Apogonidae, of ray-finned fishes found in the Atlantic, Indian, and Pacific Oceans; they are chiefly marine, but some species are found in brackish water and a few (notably Glossamia) are found in fresh water. A handful of species are kept in the aquarium and are popular as small, peaceful, and colourful fish. The family includes about 370 species.
They are generally small fish, with most species being less than 10 cm (3.9 in), and are often brightly coloured. They are distinguished by their large mouths, and the division of the dorsal fin into two separate fins. Most species live in tropical or subtropical waters, where they inhabit coral reefs and lagoons.
Clownfishor anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild, they all form symbiotic mutualisms with sea anemones. Depending on species, anemonefish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 15–16 cm, while the smallest barely achieve 7–8 cm.
Serranus is a genus of fish in the family Serranidae. It is one of five genera known commonly as the "Atlantic dwarf sea basses". These fish are hermaphrodites, each individual possessing functional male and female reproductive tissues. When a pair spawns, one fish acts as a male and the other acts as a female.
Crustaceans (Crustacea) form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 50,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg).
Oval, compressed body. Short head and small mouth. Adults are brownish, while young fish are an almost flourescent shade of blue. Lives around rocky bottoms and near posidonia meadows, from 4-5 metres to 50. Maximum size 15 centimeters.
Common dentex (Dentex dentex) is a species of Sparidae fish. Dentex is common in the Mediterranean Sea, but also seen in the Black Sea and the Eastern Atlantic Ocean from the British Islands to Mauretania, sometimes up to Senegal and Canary Islands. It lives in sandy or stony deeps, to 200 m, and is an active predator, feeding on other fish, mollusca and cephalopods.
It is usually solitary, although younger dentex form schools and are less elusive. Adult dentex can reach a length of one metre, and weigh up to 14 kg.
Youngs dentexes have a slightly different livery, brown-blue with blue fins, than adults, which are grey-blue.
