Orcas Toss Dolphins in Rare, Recorded Hunt Off Monterey Bay

Filmed by whale‑watch crews, the footage offers rare firsthand evidence of cooperative transient orca hunting.

Overview

  • Observers on Sanctuary Cruises captured video and photos of a pod of orcas repeatedly leaping and tossing long‑beaked common dolphins during a hunt seen on Sunday.
  • Crew members estimated the whales launched at prey 10 to 15 times and reported the pod may have killed as many as five dolphins, though exact counts remain unconfirmed.
  • Researchers and reporters identified the group as members of CA140B (Louise’s Pod), including the male CA151 known as “Jimmy,” linking the behavior to a known northern California family.
  • Scientists called the event unusual for its frequency and intensity but stressed it fits natural predator‑prey dynamics, and they said footage from regular whale‑watch operations can be valuable to research.
  • The sighting underlines seasonal risks for dense dolphin aggregations that gather in Monterey Bay to feed on anchovies and gives experts additional, though preliminary, material to study cooperative hunting tactics.
