- Three-spined sticklebackGasterosteus aculeatus, or the three-spined stickleback, is a fish native to most inland and coastal waters north of 30°N1. It has great morphological variation throughout its range, making it a subject of scientific study for evolution and population genetics1. It is a generalist carnivore, feeding on benthic invertebrates and zooplankton, depending on its form2. It has a predation cycle that consists of search, pursuit, attack, and capture2.Learn more:✕This summary was generated using AI based on multiple online sources.
