The gannets are large black and white birds, with long pointed wings and long bills. Northern gannets are the largest seabirds in the North Atlantic, with a wingspan of up to 2 meters. The other two species occur in the temperate seas around southern Africa and southern Australia and New Zealand.
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-wrap, 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.
The gannet's supposed capacity for eating large quantities of fish has led to "gannet" becoming a disapproving description of somebody who eats excessively, similar to "glutton".
