Researchers from the Monterey Bay Aquarium were tagging sharks and releasing them off the coast of Manhattan Beach Tuesday, said Capt. Kyle Daniels of the Los Angeles County Lifeguards.
A Manhattan Beach resident who spotted the scene said there were two sharks, a seven-footer and four-footer, a boat with a purse sein, a helicopter overhead and a lifeguard on a jet ski from about 12 noon until 1:30 p.m. Daniels confirmed the account.
Daniels said sharks have been seen "consistently enough" in the area's coastal waters "so they're checking them out."
The researchers, believed to be marine biologists, have a permit to tag and release sharks, he said.
