OverviewAI-generated

The three-spined stickleback, scientifically named *Gasterosteus aculeatus*, is a species of fish classified within the family Gasterosteidae. It belongs to the order Perciformes, class Teleostei, and phylum Chordata. The species was described by Linnaeus in 1758 and is accepted as a valid taxon. Its parent taxon is *Gasterosteus*.

This organism inhabits marine, brackish, and freshwater environments. It is also referred to by common names such as Burnstickle, Espinocho, Espinós, Espinosillo, and Espinoso. In the wild, the maximum longevity for this species is eight years. The IUCN Red List assessed its conservation status as Least Concern in 2019.

Encyclopedic overview

The three-spined stickleback (Gasterosteus aculeatus) is a fish native to most inland and coastal waters north of 30°N. It has long been a subject of scientific study for many reasons. It shows great morphological variation throughout its range, ideal for questions about evolution and population genetics. Many populations are anadromous (they live in seawater but breed in fresh or brackish water) and very tolerant of changes in salinity, a subject of interest to physiologists. It displays elaborate breeding behavior (defending a territory, building a nest, taking care of the eggs and fry) and it can be social (living in shoals outside the breeding season) making it a popular subject of inquiry in fish ethology and behavioral ecology. Its antipredator adaptations, host-parasite interactions, sensory physiology, reproductive physiology, and endocrinology have also been much studied. Facilitating these studies is the fact that the three-spined stickleback is easy to find in nature and easy to keep in aquaria.
