Dear MARMAM Subscribers,

We are proud to announce a recent review on hearing in cetaceans 
published in: *Advances in Marine Biology

natural history to experimental biology. Advances in Marine Biology.

Sound is a primary sensory cue for most marine mammals, and this is 
especially true for cetaceans. To passively and actively acquire 
information abouttheir environment, cetaceans have some of the most 
derived ears of all mammals, capable of sophisticated, sensitive hearing 
and auditory processing. These capabilities have developed for survival 
in an underwater world where sound travels five times faster than in 
air, and where light is quickly attenuated and often limited at depth, 
at night, and in murky waters. Cetacean auditory evolution has 
capitalized on the ubiquity of sound cues and the efficiency of 
underwater acoustic communication. The sense of hearing is central to 
cetacean sensory ecology, enabling vital behaviours such as locating 
prey, detecting predators, identifying conspecifics, and navigating. 
Increasing levels of anthropogenic ocean noise appears to influence many 
of these activities.
Here, we describe the historical progress of investigations on cetacean 
hearing, with a particular focus on odontocetes and recent advancements. 
While this broad topic has been studied for several centuries, new 
technologies in the past two decades have been leveraged to improve our 
understanding of a wide range of taxa, including some of the most 
elusive species. This chapter addresses topics including how sounds are 
received, what sounds are detected, hearing mechanisms for complex 
acoustic scenes, recent anatomical and physiological studies, the 
potential impacts of noise, and mysticete hearing. We conclude by 
identifying emerging research topics and areas which require greater focus.
