Abstract
⺠Nasal phonic lips are the site of sonar signal generation in bottlenose dolphins. ⺠Evidence indicates at least two sonar signal generators exist in most odontocetes. ⺠Anatomy suggests that all extant Odontoceti use the phonic lips and similar mechanism. ⺠Muscular formation of grooves in the nasal mucosa direct air flow to the phonic lips.
