An estimated 10-foot great white shark was spotted feeding on a harbor seal carcass Tuesday off La Jolla, by passengers aboard the Privateer out of San Diego Whale Watch.
Naturalist Melissa Panfili Galieti, whose image and video footage accompany this post, said the sighting was 4.5 miles offshore and that the seal was headless when the vessel arrived.
"We watched it for about 20 minutes until it completely consumed the dead seal and swam down," Galieti said via Facebook.
Last Thursday a white shark of about the same size was spotted off Dana Point. That shark had a tag at the base of its dorsal fin.
White sharks utilize Southern California and Baja California coastal waters as feeding areas and prey mostly on fish, skates and rays. After they reach 10-12 feet they begin targeting seals and sea lions.
