    The whales make groans, pops and belches typically at frequencies around 500 Hz. The purpose of the sounds is not known but may be a form of communication between whales within the same group.

    Toothed whales can also be threatened by humans more indirectly. They are unintentionally caught in fishing nets by commercial fisheries as bycatch and accidentally swallow fishhooks.

[21] It may be that a reduction in population caused by historic whaling restricted their distribution and contact with other whales, thus impeding the ...
