Observing white shark predation

In the fall, sharks migrate to the coast of California, including the Farallon Islands, to feed on pinnipeds (seals or sea-lions) when the abundance of immature animals is at its peak. This gives us a unique opportunity to study them. On September 27 as we were watching from the Lighthouse atop Southeast Farallon Island, a swarm of gulls began to circle and a pool of blood was observed in Fisherman’s Bay, indicating that a shark had just found a meal.
