The smooth sandeel (Gymnammodytes semisquamatus) is a species of sand eel in the family Ammodytidae. [2] [3]
It maximum length is 30 cm (12 in), typical adults measuring 15 cm (5.9 in). It has 53–56 dorsal soft rays and 26–31 anal soft rays. Its palate has no pointed teeth, its lateral line is branched, and only the posterior third of the body is scaly (hence the specific name semisquamatus, "half-scaled"). [4] It has 64–72 vertebrae and is golden brown or pink, with a silvery belly. [5] It is also notable for its plectrum-shaped eye. [6]
It is a demersal fish living in the waters off Great Britain, Ireland and in the North Sea. [7] [8] It made its first appearance in the Mediterranean Sea in 1990 off the Spanish coast, where there is now a stable population co-occurring with Gymnammodytes cicerelus . [9]
The smooth sandeel spawns in summer. [10] It feeds on the plankton. [5]
Sand eel or sandeel is the common name used for a considerable number of species of fish. While they are not true eels, they are eel-like in their appearance and can grow up to 30 centimetres (12 in) in length. Many species are found off the western coasts of Europe from Spain to Scotland, and in the Mediterranean and Baltic seas.
The great sand eel is the greater species of sand eel. The maximum size is 35 centimetres (14 in).
Pterois miles, the devil firefish or common lionfish, is a species of ray-finned fish native to the western Indo-Pacific region. It is frequently confused with its close relative, the red lionfish. The scientific name is from Greek pteron, meaning "wing", and Latin miles, meaning "soldier".
The shrimp scad, is a species of widespread tropical marine fish of the jack family, Carangidae. The shrimp scad is widely distributed in the tropical and subtropical western Indian Ocean and areas of the eastern Pacific Ocean, ranging from South Africa in the west to Hawaii in the east, including Japan and Australia to the north and south. The species is commonly found on inshore reefs and sandy substrates. It has the common body profile of a scad, and may be difficult to differentiate from others in the genus Alepes. It is one of the larger scads, growing to 40 cm, but often is encountered at much smaller sizes. The shrimp scad often forms large schools, and is carnivorous, consuming a variety of crustaceans and small fish. It is of moderate importance to fisheries throughout its range.
Raitt's sand eel, also known as the lesser sand eel, is a small semi-pelagic ray-finned fish found in the North Atlantic Ocean. The Raitt's sand eel is member of the family Ammodytidae which includes all 31 species of sand eels, often referred to as sand lances. Contrary to their name sand eels, including Raitt's sand eel, are not true eels and instead belong to the order of “weever-like” fishes, the Trachiniformes.
The bartail flathead, also known as the Indian flathead, gobi or Indo-Pacific flathead, is a species of largely marine ray-finned fish belonging to the family Platycephalidae, the flatheads. This species is found in the Indian Ocean and the Western Pacific Ocean, and has invaded the eastern Mediterranean Sea.

Pisodonophis semicinctus is an eel in the family Ophichthidae. First described by John Richardson in 1848., it is a marine, subtropical eel which is known in the eastern Atlantic Ocean from Gibraltar to Angola. It was first recorded in the Mediterranean Sea in 1958 off Algeria and is now found on both shores of the western Basin. It dwells at a depth range of 10 to 30 m and inhabits the continental shelf, where it forms burrows in sand and mud. Males can reach a maximum total length of 80 cm, but more commonly reach a TL of 60 cm.

Stephanolepis diaspros, commonly known as the reticulated filefish or the reticulated leatherjacket, is a species of bony fish, a ray-finned fish in the family Monacanthidae. Its natural range is the western Indian Ocean but it is also one of the species which has colonised the Mediterranean through the Suez Canal by Lessepsian migration from the Red Sea.
Apogonichthyoides pharaonis, the Pharaoh cardinalfish, is a species of cardinalfish from the family Apogonidae which is found the western Indian Ocean and Red Sea. It is one of a group of species which have colonised the eastern Mediterranean Sea from the Red Sea via the Suez Canal, a process known as Lessepsian migration.
