Gannets hunt fish by diving from a height into the sea and pursuing their prey underwater. Gannets have a number of adaptations which enable them to do this:

  • they have no external nostrils;
  • they have air sacs in their face and chest under their skin which act like bubble wrapping, cushioning the impact with the water;
  • their eyes are positioned far enough forward on their face to give them binocular vision, allowing them to judge distances accurately.

Gannets can dive from a height of 30 m, achieving speeds of 100 km/h as they strike the water, enabling them to catch fish much deeper than most airborne birds.
