Syngnathus is a genus of fish in the family Syngnathidae found in marine, brackish and sometimes fresh waters of the Atlantic, Indian and Pacific Ocean. Fossils of these species are found from the Oligocene to the Pleistocene. They are known from various localities of Greece, Italy, Germany and United States.
The greater pipefish is a pipefish of the family Syngnathidae. It is a seawater fish and the type species of the genus Syngnathus.
The lesser pipefish or Nilsson's pipefish is a pipefish similar to the greater pipefish, but with no crest above the head. Usually it reaches up to 17 centimetres (6.7 in) in length, maximally 18 centimetres (7.1 in), although in South Wales they are usually not more than 10 to 13 centimetres long. They have a light to dark green-brown colour with bar-like markings on the sides.
The black-striped pipefish is a species of fish in the family Syngnathidae. It is found in the eastern Atlantic from the southern Gulf of Biscay to Gibraltar, also in the Mediterranean and Black Seas. As the introduced species it is mentioned in the Caspian Sea and fresh waters of its basin.
The estuarine pipefish or river pipefish is a species of fish in the family Syngnathidae. It is endemic to South Africa and has been sporadically recorded in the estuarine portions of the Kariega, Kasouga, Bushmans, East Kleinemonde and West Kleinemonde rivers. It can be readily distinguished from another southern African pipefish with which it shares its habitat, S. temminckii, by its much shorter snout. The estuarine pipefish is most commonly found in beds of the eelgrass Zostera capensis.
The straightnose pipefish is a species of pipefish which lives in brackish water in the northeastern Atlantic, the Baltic, Mediterranean and Black Sea.
The Pacific seaweed pipefish is a species of pipefish, found in the north-western Pacific Ocean, near Vladivostok (Russia), southern to Gulf of Tonkin. It is a marine, oceanic demersal fish, up to 30 centimetres (12 in) length. It is common in beds of Zostera sea grass.
The northern pipefish is a northwest Atlantic species of fish belonging to the family Syngnathidae.
The barred pipefish is a species of the pipefishes, widespread in the eastern pacific from the Southern California, United States, to northern Peru. Marine / brackishwater subtropical demersal fish, up to 18.0 cm length.
The southern pipefish is a pipefish species that inhabits the Southwest Atlantic near Uruguay. It is a marine subtropical demersal fish. This species has been recorded among beds of Ruppia maritima in the Lagoa dos Patos in southern Brazil, and apparently they spend the whole of their lives in sea grass beds. It is a carnivorous species which feeds mainly on copepods and isopods, although the females consume a wider variety of prey. It is an ovoviviparous fish, in which the males bear the fertilised eggs inside a brood pouch located beneath its tail. During the breeding season they are sexually dimorphic which indicates that the species is probably polygamous.
Guadalupe pipefish is a pipefish species, inhabits the Eastern Central Pacific, endemic to Guadalupe Island in Mexico. Marine subtropical demersal fish, up to 20.4 centimetres (8.0 in) length.
The chain pipefish is a pipefish species. It inhabits the western Atlantic from Virginia, Bermuda and northern Gulf of Mexico to Campeche and Jamaica, but is absent from the Bahamas. It is a marine subtropical reef-associated fish, up to 38 cm length.
The Yucatán pipefish is a demersal fish species native to the Gulf of Mexico.
The kelp pipefish is a species of pipefish. It inhabits the eastern Pacific from the Bodega Bay in northern California, United States, to southern Baja California, Mexico. It is a marine subtropical demersal fish, up to 50 centimetres (20 in) length.
The Chocolate pipefish is a species of the pipefishes. Widespread in the Eastern Pacific from Redondo Beach in southern California, United States, to central Baja California, Mexico. Marine subtropical demersal fish, up to 25 cm length.
Barcheek pipefish, Syngnathus exilis, is a species of the pipefishes. Widespread in the Eastern Pacific from the Half Moon Bay in central California, United States, to south central Baja California and Guadalupe Island, Mexico. Marine subtropical demersal fish, up to 25 cm length.
Syngnathus temminckii is the most common pipefish in southern African estuaries, ranging from Walvis Bay (Namibia) to the Tugela River on the east coast of South Africa.
Gyrodactylus leptorhynchi is a small monogenean obligate ectoparasite which parasitizes freshwater bay pipefish. Gyrodactylus leptorhynchi is the seventh Gyrodactylus species known to infect bay pipefish and the first characterized along the Pacific coast of North America. The parasite can get into captive fish environments, such as fish farms and aquariums, where it may spread in as little as 10 days. Gyrodactylus species are known to centralize on the brood pouch in male fish, this may allow for transmission to newly hatched young. However, in Gyrodactylus leptorhynchi the parasite was found mostly found attached to body surfaces such as the dorsal fins.
Microphis pleurostictus, the Luzon River pipefish (湖沼腹囊海龍),is a species of freshwater pipefish belonging to the family Syngnathidae.
Phoxocampus diacanthus, also known as the obscure pipefish or spined pipefish, is a species of marine fish belonging to the family Sygnathidae. It can be found inhabiting reefs throughout the Indo-Pacific from Japan and Sri Lanka to Samoa and New Caledonia in the south. Its diet likely consists of small crustaceans. Reproduction occurs through ovoviviparity in which the males brood eggs before giving live birth.
