The whales are known for their tusks which can reach 2.6m (9ft) in length, earning them comparisons with mythological unicorns.
The tusk is an exaggerated front tooth and scientists have discovered that it helps the animals sense changes in their environment.
Experts suggest males could use the tusks to seek out mates or food.
