Hearing Tests on Wild Whales

Caption

In addition to the auditory testing, the researchers also performed a physical exam to assess the overall health, sex, and estimated age of each animal and obtained skin, breath, and blood samples to collect information on the whales' hormone levels, microbiome bacteria, and other health-related data. Satellite transmitters were attached to some of the whales before release to study the whales' movements. All work conducted under NMFS permit no. 14245.
