Blue whales, the largest animals on Earth, are not immune to predation by orcas, which can attack both adults and calves. A study confirms that killer whales pose a significant threat to all baleen whales. Notably, blue whales have developed a strategy called 'acoustic crypsis', allowing them to sing at frequencies that orcas cannot detect, potentially aiding their survival. Researcher Robert Pitman highlights the magnitude of orca predation as the largest predation event currently known. This evolving dynamic emphasizes the complex interactions within marine ecosystems and the adaptability of these marine giants.
Killer whale attacks on large whales is the biggest predation event that occurs on the planet, suggesting a significant ecological impact and predator-prey dynamics.
The concept of acoustic crypsis reveals that blue whales can sing at frequencies undetectable by orcas, highlighting an evolutionary advantage against predation.
