Video by bertiegregory / Basking sharks cruise at the surface on a feeding run near the Inner Hebrides, Scotland. Although they're the second biggest fish in the sea, these sharks have tiny prey. They eat zooplankton, with a particular preference for a group of tiny crustaceans called copepods. After locating a zooplankton patch, the sharks open their giant mouths and swim through it. Yum.
