A BBC/National Geographic film crew have recorded rare footage of humpback whales intervening in a killer whale hunt.
Ms Bromley told BBC Nature: “we saw a lot of grey shapes in the water and quickly realised they were humpbacks.” According to the crew the additional whales were not just observers of the hunt but were actively involved.
Humpback whales are known for their impressive range of calls, including a high-pitched “trumpeting” noise made when they are agitated. The humpbacks at Monterey Bay were trumpeting, diving and slapping their pectoral fins against the water. “It didn’t seem at all like they were confused… they were definitely there with a purpose,” said Ms Bromley.
