A dead whale washed up along the southern Solana Beach shoreline Dec. 11.
The carcass, which was about 15 to 20 feet long, was spotted near the access point to Del Mar Shores about 7:30 a.m., Solana Beach lifeguard Sgt. Rob McPhee said.
It was not immediately clear how the whale died, but personnel from the National Marine Fisheries Service were performing tests.
SeaWorld workers also were summoned, McPhee said.
McPhee said the carcass couldn’t be removed until low tide.
A National Weather Service high surf warning for the beaches will remain in effect until the late afternoon on Dec. 13.
