The eerie noises from the Mariana Trench, recorded in 2014, were reanalysed by NOAA scientists who concluded they were produced by Bryde's whales, not baleen whales.
The sounds, first dubbed 'biotwangs', last between 2.5 and 3.5 seconds and include deep moans and a metallic finish, baffling researchers initially.
Dr. Ann Allen's team used visual and acoustic surveys to study the sounds, concluding they originated from Bryde's whales, offering a new perspective on deep-ocean acoustics.
Sharon Nieukirk noted the unique characteristics of the low-frequency moaning from whales, remarking on how we rarely discover new baleen whale calls.
