The Red Sea goby (Silhouettea aegyptia) is a species of true goby from the family Gobiidae. It was once a species confined to the Red Sea but it has colonised the Suez Canal and the south-eastern Mediterranean by Lessepsian migration.
The Red Sea goby is marked with many dark vertical spots which have reddish brown edges on a cream background colour. There are 9 or 10 dark spots along the lateral line. It has a short snout and in males the first spine of the first dorsal fin is elongated. There are no scales on the head and nape and there are 24–28 scales in lateral line. It grows to a maximum length of 4–5 centimetres (1.6–2.0 in). [4]
The Red Sea goby is native to the northern Red Sea. [5] It was described by Paul Chabanaud in 1933 from type specimens collected in Lake Timsah on the Suez Canal from where it obviously entered the Mediterranean Sea where it was first recorded in Bardawil Lagoon, Egypt, in 1986. [5] It is now rather common from Sinai to Israel. [6] [4]
The Red Sea goby can be found on sandy substrates in inshore, shallow waters where it feeds on harpacticoid copepods and nematodes, as well as oligochaetes, gastropods and other meiofauna. [3] This species conceals itself by burying itself into the sand up to the level of its eyes. [5] They probably live no longer than 2 years. [3] They reach sexual maturity at a year old. [4] The breeding season is from February to September, [4] peaking in the Red Sea is from May onwards. Females of 2.7–3.25 centimetres (1.06–1.28 in) SL carry 305–408 eggs; [7] it is a repeat spawner with an extended breeding season. [5]
The sergeant major or píntano is a species of damselfish. It grows to a maximum length of about 22.9 centimetres (9.0 in).
The sand goby, also known as a polewig or pollybait, is a species of ray-finned fish native to marine and brackish European waters from the Baltic Sea through the Mediterranean Sea and into the Black Sea where it occurs in sandy or muddy areas of inshore waters at depths of from 4 to 200 metres. This species can reach a length of 11 centimetres (4.3 in) TL. This species is sometimes kept in public aquariums. The sand goby is of a sandy colour, with darker markings on the sides and a creamy-white underside. In the breeding season the male fish has blue spot at the rear of the first dorsal fin, ringed with white. The fish has a slender body, and the head is about a quarter of the total length.

Tetrosomus gibbosus, commonly called camel cowfish because of the hump on its dorsal keel, is one of 22 species in the boxfish family, Ostraciidae. It is a ray finned fish. Other common names include helmet cowfish, humpback turretfish and thornbacked boxfish. It is most closely related to T. reipublicae, the smallspine turretfish. T. gibbosus is a species of boxfish found in the wide Indo-West Pacific. It has been recorded since 1988 on rare occasions in the Levantine waters of the Mediterranean Sea, likely following entry via the Suez Canal. It is the first species from the family Ostraciidae to be found in the Mediterranean Sea.

The dusky spinefoot, also known the squaretail rabbitfish,is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is native to the western Indian Ocean which has spread to the Mediterranean Sea through the Suez Canal. Its fin spines contain venom. It is regarded as a food fish.
Crystallogobius linearis, the crystal goby, is a species of goby native to the Atlantic coasts of Europe and the Mediterranean Sea where it can be found at depths of from 1 to 400 metres. Males of this species grow to a length of 4.7 centimetres (1.9 in) SL while females only reach 3.9 centimetres (1.5 in) SL. This species is the only known member of its genus. The name Crystallogobius comes from the Latin words cristallum, meaning "crystal", and gobius, meaning gudgeon.
The largetooth goby, also known as Wilbur's goby, is a species of ray-finned fish from the family Gobiidae which is native to the Indo-Pacific from the Seychelles to Micronesia. Its known range has been extended to the Red Sea as specimens were photographed at one site and collected at another site off Egypt. This species lives in sheltered marine waters at depths of from 0 to 20 metres preferring areas with sandy substrates. This species grows to a length of 6.5 centimetres (2.6 in) SL. This species is the only known member of its genus. This species is not obviously sexually dimorphic and it has a background colour of pale brown to greenish-brown and a pale ventral side. The body is marked with brown and white spots, pairs of larger brown spots create a mid-lateral row along its flanks and there is a dark spot on the caudal fin peduncle. It has a brown blotch on the cheek and a series of short brown bars along its back. The largetooth goby is a solitary fish which is found in coastal bays, lagoons and estuaries over fine sandy substrates close to the margins of reefs or silt beds in the vicinity of sheltered and often turbid coastal reefs. It is most frequently collected from shallow waters to 7 metres (23 ft), around coral reefs but off southern Japan, the largetooth goby occurs at the bottom of sandy bays. The specific name honours the American physician, Ray Lyman Wilbur (1875–1949) who was president of Stanford University from 1916–1943, as well as being the United States Secretary of the Interior from 1929–1933. Wilbur helped the author, Herre, get to Palau, the type locality of this species.

Vanderhorstia mertensi, Mertens' shrimp goby or the slender shrimp goby, is a ray-finned fish species native to the Red Sea, Japan, Papua-New Guinea and the Great Barrier Reef. Male individuals can reach a length of 11 cm in total. In 2008 a first specimen was collected in the Mediterranean Sea, in the Gulf of Fethiye, southern Turkey, where it was found on sandy bottoms in the vicinity of beds of sea grass. It is now common in Israel, Turkey and Greece. According to the Mediterranean Science Commission this species most likely entered the Mediterranean via the Suez Canal from the Red Sea.
