Killer Whales Use Stealth Approach When Hunting Prey
2013-12-04 04:57:23

[ Watch the Video: Stealthy Tactics Used By Orca To Catch Their Prey ] redOrbit Staff & Wire Reports - Your Universe Online Newly discovered evidence that killer whales can hunt marine mammals during the nighttime has led scientists to suggest that the creatures can use their hearing to help locate prey, according to research presented at the 166th Meeting of the Acoustical Society of America (ASA). For example, the study authors said that the whales eavesdrop on male harbor...

Mass Stranding Of Melon-headed Whales Attributed To Sonar Mapping
2013-09-25 15:48:07

Wildlife Conservation Society An independent scientific review panel has concluded that the mass stranding of approximately 100 melon-headed whales in the Loza Lagoon system in northwest Madagascar in 2008 was primarily triggered by acoustic stimuli, more specifically, a multi-beam echosounder system operated by a survey vessel contracted by ExxonMobil Exploration and Production (Northern Madagascar) Limited. In response to the event and with assistance from IFAW, WCS led an...

Echolocation - With Practice, Anyone Can Learn It
2013-08-30 04:23:17

redOrbit Staff & Wire Reports - Your Universe Online Humans can learn to use echolocation to navigate and to find objects, according to new research appearing in the latest edition of the biology journal Proceedings of the Royal Society B. Professor Lutz Wiegrebe of the Ludwig-Maximilians-Universitaet (LMU) Department of Neurobiology and colleagues have now shown how people can acquire the capacity for echolocation, though they emphasize doing so takes a considerable amount of time...

The larger the moth, the better hearing senses it needs if it wants to avoid its worst enemy, the bat. A large moth is easier to detect for a bat, and therefore evolution has forced large moths to develop larger and more sensitive ears. But the improved hearing comes at a price, says sound researcher Annemarie Surlykke from University of Southern Denmark. Bats orient themselves through echolocation, and they find their prey by emitting calls and then process the echoes reflected back to...
