The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...

Some marine animals, such as whales and dolphins, use echolocation or "biosonar" systems to locate predators and prey. It is conjectured that active sonar transmitters could confuse these animals and interfere with basic biological functions such as feeding and mating.
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
The creature was discovered in 2007 by a team of marine biologists about 2,500 meters deep in the Celebes Sea in the western Pacific Ocean. RELATED: Photos of bizarre sea animals
Aquatic animals use visual signals such as movement, postures, colouration, patterns and size. A change in these visual traits can also be considered a signal. Coastal or oceanic species are more likely to use visual signals than species inhabiting the riverine or turbid environment, due to the poor light transmission in turbid areas or in ...
On the U.S. East Coast, Sperm whales and other marine mammals that use echolocation to find their prey are mistaking the acoustic signature of plastic trash for squid and other food species. And ...
