  1. 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.

    De driedoornige stekelbaars (Gasterosteus aculeatus) is een kleine zijdelings afgeplatte vis uit de familie van de stekelbaarzen (Gasterosteidae). Op de rug bevinden zich drie harde stekels, soms zijn dit er twee of vier. Ook achter iedere borstvin en voor de anaalvin bevind zich een stekel.

    Gasterosteus aculeatus occupy a wide range of habitats. They have been found in small, ephemeral streams in southern California and in more permanent flowing waters of variable sizes. These fish do not tolerate high-gradient streams, and they are rarely found in habitats more than a few hundred meters above sea level.
