Gannets Diving For Fish, Shetland Islands, Scotland, United Kingdom

• Northern gannet (also known as "solan goose"), Morus bassanus
• Cape gannet, Morus capensis
• Australasian gannet, Morus serrator
Most fossil gannets are from the Late Miocene or Pliocene, a time when the diversity of seabirds in general was much higher than today. It is not completely clear what caused the decline in species at the end of the Pleistocene; increased competition due to the spread of marine mammals may have played a role.
