Acoustic parameters of sounds emitted by Sotalia guianensis : dialects or acoustic plasticity [PDF]
AbstractSelective pressure from the environment on species may select adaptations as a whole, including the specific context of acoustics. Some authors report that the acoustic repertoire of Sotalia guianensis presents dialects as a geographical reflection. However, others propose that the environmental characteristics are the factor that imposes these

Acoustically evoked potentials in two cephalopods inferred using the auditory brainstem response (ABR) approach [PDF]
It is still a matter of debate whether cephalopods can detect sound frequencies above 400 Hz. So far there is no proof for the detection of underwater sound above 400 Hz via a physiological approach.

The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
