Biologist: Orca attacks on gray whales up in California bay
Killer whales are on an unprecedented killing spree in California’s Monterey Bay, attacking and feeding on gray whale calves, a marine biologist said.
Since April 20, orcas have killed four gray whale calves in eight days, Nancy Black said Friday.
Black, who co-owns Monterey Bay Whale Watch, says a family of nine killer whales has taken part in all of the attacks, but the first killing involved 33 orcas.
It’s not uncommon for orcas to prey on gray whale calves, says Shawn Johnson, director of veterinary science at California’s Marine Mammal Center. He hadn’t heard about the latest killings.
Black called their frequency unprecedented.
