Gannets and Dolphins
Manage episode 431762309 series 2381
Northern Gannets, fish-eating seabirds, dive headfirst into the ocean at speeds of up to 60 miles an hour, pursuing their prey. Sometimes, they get help. Dolphins herd fish into dense, frantic concentrations near the surface, while gannets take advantage and plunge into the shoals from aloft. Scientists call this a multi-species feeding association, a frequent phenomenon on the ocean’s surface. This may seem like evidence of cooperation between species, but it’s more about opportunity. Kittiwakes and gulls, as well as seals and whales, may join in, too.
