Studies surrounding the evolution of sensory system anatomy in cetaceans over the last~
100 years have shed light on aspects of the early evolution of hearing sensitivities, the small …

Whales receive underwater sounds through a fundamentally different mechanism than their
close terrestrial relatives. Instead of hearing through the ear canal, cetaceans hear through …

This study compares the bony ear morphology of freshwater and marine odontocetes
(toothed whales). Odontocetes are unique among marine mammals in two important …

Baleen whales (Mysticeti) have an extraordinary fossil record documenting the transition
from toothed raptorial taxa to modern species that bear baleen plates, keratinous bristles …

Mysticeti (baleen whales) and Odontoceti (toothed whales) today greatly differ in their
hearing abilities: Mysticeti are presumed to be sensitive to infrasonic noises [1–3], whereas …

The whale ear, initially designed for hearing in air, became adapted for hearing underwater
in less than ten million years of evolution. This study describes the evolution of underwater …

Evolutionary adaptations of toothed whales to their aquatic habitat are expressed in a variety
of morpho‐genetic trends, involving every part of these animals. Some of the most …

Toothed whales (odontocetes) emit high-frequency underwater sounds (echolocate)—an
extreme and unique innovation allowing them to sense their prey and environment. Their …

The inner ear of toothed whales (odontocetes) is known to have evolved particular shapes
related to their abilities to echolocate and move under water. While the origin of these …

Cetaceans (baleen and toothed whales) present a unique set of adaptations for life in water.
Among other abilities, the two living groups can hear and produce different sound …
