Three rare whale species photographed together

A researcher taking part in aerial surveys around Cape Cod Bay has captured a very unusual photograph of three rare whales together.

A three-year study discovered 129 dolphins in the research area, with around one dolphin per sq. km, the highest density ever recorded for this species in northern Australia.
