Many stickleback traits can vary a great deal between freshwater populations, including the number of bony lateral plates, a few of which can be seen towards the posterior edge of this mesh, and the number and length of gill rakers and pharyngeal teeth, which can be seen inside the mouth. Three subspecies are currently recognized by the IUCN:
Pungitius hellenicus, the Greek ninespine stickleback or ellinopygósteos, is a species of fish in the family Gasterosteidae. It is endemic to Greece. Its natural habitats are rivers and freshwater spring. It is threatened by habitat loss and considered critically endangered in the International Red List of IUCN, Bern Convention (Appendix III).
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 ] Flying fish can fly up to 400 m (1,300 ft) at speeds of more than 70 kilometres per hour (43 mph) at a maximum altitude of more than 6 m (20 ft), much ...
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.
The marine threespine stickleback exhibits a larger and thicker opercular series. This provides evidence that there was an evolutionary change in the operculum bone. The thicker and more dense bone may have been favored due to selective pressures exerted from the threespine stickleback's environment.
Apeltes is a monospecific genus old ray-finned fish belonging to the family Gasterosteidae, the sticklebacks.The only species in the genus is A. quadracus, the fourspine stickleback or bloody stickleback, which lives in freshwater, brackish and benthopelagic environments of the northwestern Atlantic Ocean between Newfoundland and South Carolina.

The ninespine stickleback is a euryhaline and eurythermal species of teleost fish, occupying both freshwater and marine habitats in higher latitudes of the world. Recently, this species has been under great examination due to pond populations' adaptations of morphology, life history, and behavior which separates them from their marine ...
