Dolphins swim in the background as this Cape Gannet pursues its prey.
Off the coast of South Africa, the water is a beautiful, clear blue. Dolphins swim past playfully, and a huge shoal of silver sardines glitters in the sun as a bird glides by, pursuing the sardines like a feathery torpedo. Wait a minute… a bird 25 feet (eight meters) underwater? But it’s not a trick; the creature in question is a Cape Gannet, and this species doesn’t mind getting very wet to catch its prey.
