Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT Most dolphin species produce broadband biosonar clicks for echolocating prey, and whistles and burst‐pulsed calls for communication purposes. Seven dolphin species were previously reported to only produce clicks of a narrowband high‐frequency (NBHF) type, very similar to the clicks produced by porpoises.

Active control of acoustic field-of-view in a biosonar system. [PDF]
PLoS Biology, 2011 Active-sensing systems abound in nature, but little is known about systematic strategies that are used by these systems to scan the environment. Here, we addressed this question by studying echolocating bats, animals that have the ability to point their ...

Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT Assessing foraging behavior of harbor porpoise (Phocoena phocoena) from acoustic data has become increasingly common. Yet, a wide range of analytical methods is currently used, often without formal evaluation of their comparability. This lack of cross‐method validation limits the ability to compare findings across studies and interpret ...

Variation in the production rate of biosonar signals in freshwater porpoises
, 2013 The biosonar (click train) production rate of ten Yangtze finless porpoises and their behavior were examined using animal-borne data loggers. The sound production rate varied from 0 to 290 click trains per 10-min time interval.

MCM trials with Biosonar system
, 2012 In this paper we present the results of MCM trials using a Biosonar system mounted on the AUV (autonomous underwater vehicle) REMUS 100. The trials were run in Lochearnhead in Scotland. Two mine-like objects were put on the seafloor.

Analog VLSI Models of Range-Tuned Neurons in the Bat Echolocation System
EURASIP Journal on Advances in Signal Processing, 2003 Bat echolocation is a fascinating topic of research for both neuroscientists and engineers, due to the complex and extremely time-constrained nature of the problem and its potential for application to engineered systems.

ChemCatChem, Volume 18, Issue 15, 14 August 2026.To selectively detect minority sites and measure their catalytic properties is challenging. As the bat uses the echo of insects to locate them in darkness, we here demonstrate that the echo‐signal of small temperature modulations applied to a catalyst can be used to reveal minority sites.

Following a foraging fish-finder: diel habitat use of Blainville's beaked whales revealed by echolocation. [PDF]
PLoS ONE, 2011 Simultaneous high resolution sampling of predator behavior and habitat characteristics is often difficult to achieve despite its importance in understanding the foraging decisions and habitat use of predators.

Spatiotemporal patterning of acoustic gaze in echolocating bats navigating gaps in clutter
iScience, 2021 Summary: We challenged four big brown bats to maneuver through abrupt turns in narrow corridors surrounded by dense acoustic clutter. We quantified bats' performance, sonar beam focus, and sensory acquisition rate.
