[^3]\n\nYoung beluga whales have a unique acoustic signature, but their calls have a range 18 times shorter than adult calls, making them vulnerable to being lost due to ship noise. [^4]\n\nResearchers have been studying whale communication since the earliest known recording of whale song was made in 1949.
