The brook stickleback was first formally described as Gasterosteus inconstans in 1840 by the American naturalist Jared Potter Kirtland with its type locality given as Trumbull County, Ohio. [8] In 1876 David Starr Jordan proposed the monospecific genus Eucalia for the brook stickleback but Jordan's name was invalid because it was preoccupied in ...
Gasterosteus doryssus is an extinct species of freshwater stickleback fish that inhabited inland freshwater habitats of the North American Great Basin during the Miocene.It is known from thousands of articulated fossil skeletons, comprising various age classes and two different ecomorphs, discovered in diatomite deposits of the Truckee Formation near Hazen, Nevada.
There are currently 6 recognized species in this genus: Gasterosteus aculeatus Linnaeus, 1758 (Three-spined stickleback) †Gasterosteus crenobiontus Băcescu & R. Mayer, 1956 (Techirghiol stickleback) Gasterosteus islandicus Sauvage, 1874 (Iceland stickleback) Gasterosteus microcephalus Girard, 1854 (Smallhead stickleback)
The stickleback family, Gasterosteidae, was first proposed as a family by the French zoologist Charles Lucien Bonaparte in 1831. [1] It was long thought that the sticklebacks and their relatives made up a suborder, the Gasterosteoidei, of the order Gasterostiformes with the sea horses and pipefishes making up the suborder Syngnathoidei.
Eel form are independent in the North American brook lamprey, neotropical eels, and the African spiny eel. [124] Stickleback fish have repeatedly moved between marine and freshwater environments, with widespread convergent evolution to adapt and readapt to these environments in different species. [125]
Gasterosteoidei is treated as a suborder within the order Scorpaeniformes in the 5th edition of Fishes of the World, [2] but in other phylogenetic classifications it is treated as the infraorder Gasterosteales within the suborder Cottoidei or as a sister clade to the Zoarcales in the order Zoarciformes.

Stickleback next to extracted Schistocephalus solidus plerocercoids. The three-spined stickleback is a secondary intermediate host for the hermaphroditic parasite Schistocephalus solidus, a tapeworm of fish and fish-eating birds. The tapeworm passes into sticklebacks through its first intermediate hosts, cyclopoid copepods, when these are eaten ...
