About
The Icelandic threespine stickleback (Gasterosteus islandicus) is a freshwater fish, and one of the few vertebrate species endemic to Iceland. In some literature it is considered as a subspecies of G. aculeatus, though several authorities offer it full species status. It was first described by French biologist Henri Émile Sauvage in 1874.
