New research suggests male baleen whales looking for love sing a different tune when attracting a mate.

University of Washington professor Trevor Branch reviewed more than 250 research papers last summer .

Most of the whales more prone to flee from predators will sing at a bass level low enough to avoid being heard by killer whales.

Most killer whales have poor hearing below 1500 Hz and can't hear at all below 100 Hz.
