Species

There are currently 6 recognized species in this genus:

Additionally there are a number of fossil species including:

  • Gasterosteus abnormis Gretchina, 1981 (middle Miocene of Sakhalin, Russia)2
  • Gasterosteus doryssus (Jordan, 1907) (=Merriamella doryssa Jordan, 1907, G. apodus Mural, 1973) (late Miocene of Nevada, USA)34
  • Gasterosteus kamoensis Nazarkin, Yabumoto & Urabe, 2013 (Late Miocene of Japan)2
  • Gasterosteus orientalis Sychevskaya, 1981 (middle Miocene of Kamchatka, Russia)2

Fossils of essentially modern three-spined sticklebacks, assigned to G. aculeatus, are known from the mid-late Miocene of California, USA.5
