Marine dredging is an excavation activity carried out worldwide by many industries. Concern
about the impact dredging has on marine life, including marine mammals (cetaceans …

Evolutionary relationships among cetaceans within the family Delphinidae have been
difficult to resolve due to the high number of species and their relatively rapid radiation. This …

As awareness of the effects of anthropogenic noise on marine mammals has grown,
research has broadened from evaluating physiological responses, including injury and …

Sound plays an important role for toothed whales in foraging and communication. However,
little is known about acoustic communication in the toothed whale species that only produce …

Toothed whales are apex predators varying in size from 40-kg porpoises to 50-ton sperm
whales that all forage by emitting high-amplitude ultrasonic clicks and listening for weak …

Social delphinids employ a vocal repertoire of clicks for echolocation and whistles for
communication. Conversely, the less social and acoustically cryptic harbour porpoises …

The study of marine soundscapes is a growing field of research. Recording hardware is
becoming more accessible; there are a number of off-the-shelf autonomous recorders that …

Small odontocetes produce echolocation clicks to feed and navigate, making it an essential
function for their survival. Recently, the effect of vessel noise on small odontocetes behavior …

An increasing number of smaller odontocetes have recently been shown to produce
stereotyped narrow-band high-frequency (NBHF) echolocation clicks. Click source …

Background Unlike most mammals, toothed whale (Odontoceti) skulls lack symmetry in the
nasal and facial (nasofacial) region. This asymmetry is hypothesised to relate to …
