In the dark world of the underwater ocean, whales need to locate their prey accurately and quickly. In low-vision conditions whales use echolocation to find fish swimming nearby, and now it has been discovered that they can focus their acoustical “vision” to accurately located slightly differing objects. For this study, Laura Kloepper from the University of Hawaii and her her PhD supervisor, Paul Nachtigall, utilized the help of Kina the False Killer Whale, a species related to...

False killer whales focus echolocation clicks Hunting in the ocean's murky depths, vision is of little use, so toothed whales and dolphins (odontocetes) rely on echolocation to locate tasty morsels with incredible precision. Laura Kloepper from the University of Hawaii, USA, explains that odontocetes produce their distinctive echolocation clicks in nasal structures in the forehead and broadcast them through a fat-filled acoustic lens, called the melon. 'Studies by other people showed...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
