Scientists have finally explained why killer whales struggle to hear blue whales, and the answer may have helped the giants survive for millions of years

Some baleen whales use low-frequency songs to avoid killer whales. This acoustic crypsis helps flight species escape predators in open oceans. Blue whales, known for loud calls, sing at frequencies predators cannot hear. Natural selection favored these low-frequency calls over millions of years. This discovery reveals how predation shaped whale communication systems.
