Sphyraena viridensis, the yellowmouth barracuda or yellow barracuda is a predatory ray-finned fish from the family Sphyraenidae, the barracudas. It is found in the warmer waters of the eastern Atlantic Ocean and the Mediterranean. It is often confused with the European barracuda.
S. viridensis has a fusiform body with a long, streamlined pointed snout which has a long mouth lined with two rows of sharp, fang-like teeth and a jutting lower jaw. There are no scales on the preoperculum, unlike the European barracuda, which has scales on both the anterior and posterior margins of the preoperculum. There are numerous transverse dark bars on the dorsum; these usually extend below the lateral line, while the same lines in the European barracuda do not do so. [3] The bars fade in dead specimens. Generally, the colouration of adult S. viridensis is dark above and silvery below (this is an example of countershading), [4] while juveniles are dark yellow or greenish in colour. [5] S. viridensis is smaller than its European counterpart, growing to a standard length of 65 cm, although the average length is 35–40 cm. [4] However, specimens up to 114.5 cm have been caught off the Azores. [5] The rod caught record is 10.2 kg, which was caught off Lanzarote in the Canary Islands in 2007. [6]
The exact distribution of S. viridensis is unclear because of confusion with the European barracuda; however, it is known that it occurs in subtropical areas of the eastern Atlantic (around the Azores, Madeira, Cape Verde Islands and the Canary Islands). It has also been recorded in the Mediterranean, including off the coasts of Lebanon, [2] Israel, Algeria, Corsica and Sicily, and in the Adriatic Sea and the Aegean Sea. [3] [5]
In a study in the Azores, fish made up all of the diet of S. viridensis, with the most important species being the bluejack mackerel, which was found as having been preyed upon by 72.4% of the fish sampled and making up nearly two thirds of the weight of prey taken. [5] Other species recorded in this study included bogues, ornate wrasses and axillary sea breams, as well as an unidentified species of flying fish. [5] Unidentified fish remains were found in nearly 20% of the specimens sampled. The predatory behaviour of S. viridensis was observed in the same study; they were found to be active pursuit predators of fish, with one or many barracudas hunting together, either singling out lone prey or attacking shoals of prey fish. The pursuit was rapid and was usually over in 8–40 seconds, and the more fish involved, the higher the rate of success was. [5]
Some other known prey species of S. viridensis include the longspine snipefish, the boar fish, [5] and cephalopods and crustaceans. [4]
Juveniles of S. viridensis are preyed upon by the lizard fish. This shows that there is an overlap in habitat between the juvenile barracudas and the lizard fish, which occurs in sheltered, very enclosed bays with sandy substrates. [7]
In summer, S. viridensis may form schools of up to 180 fish (although most schools only number 30-40 fish) in areas where there are strong currents. These schools are predominantly made up of sub-adults, with the smaller fish nearer to the surface and the larger ones, usually female, at the bottom, at depths of up to 30m. In winter, the only aggregations are small groups of juveniles in shallow bays. No territorial behaviour has been observed. Schooling is thought to be an anti-predator defence, to facilitate mating (with the smaller males being attracted to the larger females), and to increase the success rate of hunting. This species does not appear to mix with other barracuda species in mixed schools, but there are reports of these fish associating with whale sharks in the Azores and an instance of them actively swimming towards a manta ray. [5]
S. viridensis is landed in small quantities in the eastern Mediterranean by fishermen using in trammel-nets and beach-seines. [4] It has been reported from markets in Turkey but it is generally caught as a bycatch, although as numbers increase in the Mediterranean, it may be becoming a more important species for fisheries.

A barracuda is a large, predatory, ray-finned fish known for its fearsome appearance and ferocious behaviour. The barracuda is a saltwater fish of the genus Sphyraena, the only genus in the family Sphyraenidae, which was named by Constantine Samuel Rafinesque in 1815. It is found in tropical and subtropical oceans worldwide ranging from the eastern border of the Atlantic Ocean to the Red Sea, on its western border the Caribbean Sea, and in tropical areas of the Pacific Ocean. Barracudas reside near the top of the water and near coral reefs and sea grasses. Barracudas are targeted by sport-fishing enthusiasts.
The Australian barracuda, arrow barracuda, Australian sea pike, sea pike, snook, or shortfin barracuda, Sphyraena novaehollandiae, is a barracuda of the genus Sphyraena which occurs in the south-western Pacific Ocean.
The blackmouth catshark is a species of catshark, and part of the family Scyliorhinidae, common in the northeastern Atlantic Ocean from Iceland to Senegal, including the Mediterranean Sea. It is typically found over the continental slope at depths of 150–1,400 m (490–4,590 ft), on or near muddy bottoms. The youngest sharks generally inhabit shallower water than the older juveniles and adults. This slim-bodied species is characterized by the black interior of its mouth, a marbled pattern of pale-edged brownish saddles or blotches along its back and tail, and a prominent saw-toothed crest of enlarged dermal denticles along the upper edge of its caudal fin. It reaches lengths of 50–79 cm (20–31 in), with sharks in the Atlantic growing larger than those in the Mediterranean.
The yellowtail barracuda is one of the smaller species of barracuda of the family Sphyraenidae, which can be found in Indo-West Pacific oceans. It has also invaded the Mediterranean through the Suez Canal from the Red Sea, making it one of the Lessepsian migrants.

The Mediterranean parrotfish is a species of parrotfish found at depths up to 50 m (160 ft) along rocky shores in the Mediterranean and the eastern Atlantic, from Portugal south to Senegal. It is generally common, but uncommon or rare in the northwestern Mediterranean and in the Adriatic Sea. It prefers relatively warm temperatures and there is an ongoing northward range expansion, possibly due to global warming. The primary adult habitat is rocky reefs, especially in areas with macroalgae, but they may visit adjacent seagrass patches. Juveniles also occur more widely in the latter habitat.
The Guachanche barracuda is an ocean-going species of game fish in the barracuda family, Sphyraenidae. It was described by the French zoologist Georges Cuvier in 1829. The description was part of the second edition of Le Règne Animal, or The Animal Kingdom. Guachanche barracuda are also known simply as guaguanche throughout much of the Caribbean. When used for food, Guaguanche barracuda are usually sold fresh or salted.
Sphyraena argentea is a predatory species of marine barracuda fish of the family Sphyraenidae. They are found in the northeast Pacific Ocean, from Cabo San Lucas, Baja California Sur north to Washington State. However, they are not common north of Point Conception in Santa Barbara County, California, usually preferring warmer waters. They can reach a length of about 1.2 metres (3.9 ft) and a weight of about 6.8 kilograms (15 lb). This species of barracuda is a very popular sport fish in Southern California.
