Journal ArticleDOI
Sound detection by the longfin squid (Loligo pealeii) studied with auditory evoked potentials: sensitivity to low-frequency particle motion and not pressure
T. Aran Mooney,T. Aran Mooney,Roger T. Hanlon,Jakob Christensen-Dalsgaard,Peter T. Madsen,Peter T. Madsen,Darlene R. Ketten,Darlene R. Ketten,Paul E. Nachtigall +8 more
TL;DR: Both the AEP response characteristics and the range of responses suggest that squid detect sound similarly to most fish, with the statocyst acting as an accelerometer through which squid detect the particle motion component of a sound field.
Journal ArticleDOI
Echolocation in two very small bats from Thailand Craseonycteris thonglongyai and Myotis siligorensis
Annemarie Surlykke,Lee A. Miller,Bertel Møhl,Bent Bach Andersen,Jakob Christensen-Dalsgaard,Morten Buhl Jørgensen +5 more
TL;DR: It is argued that the signal resemblance is due to the similarity in size and hunting behavior of the two bats both hunting insects in open areas, and that the sweep rate in this frequency range may now increase to twice the maximum rate that the vocal cords can produce directly.
Journal ArticleDOI
Directionality of the lizard ear
TL;DR: It is shown that acoustical coupling of the two eardrums in lizards produces the largest directionality of any terrestrial vertebrate ear studied, and Lizard ears are the clearest vertebrate examples of directionality generated by tympanic coupling.
Journal ArticleDOI
Hearing with an atympanic ear: good vibration and poor sound-pressure detection in the royal python, Python regius
TL;DR: Pythons, and possibly all snakes, lost effective pressure hearing with the complete reduction of a functional outer and middle ear, but have an acute vibration sensitivity that may be used for communication and detection of predators and prey.
Journal ArticleDOI
Evolution of a sensory novelty: Tympanic ears and the associated neural processing
TL;DR: It is proposed that tetrapod auditory processing may originally have been organized into low- and high-frequency streams, where only the high- frequencies processing was mediated by tympanic input, and then transformed into time and intensity pathways, respectively.
