“The findings add fuel to an already fierce debate in the research community on how the echolocation sound is produced”, says Josefin Starkhammar.,
The beam projections have different frequencies and can be sent in different directions. The advantage is probably that the dolphin can locate the object more precisely.

Dead zones form where microscopic plants, known as phytoplankton, are fertilized by excess nutrients, such as fertilizers and sewage, that are generated by human activities and dumped into the ocean by rivers, or more rarely, where they are fertilRead more
For some years, researchers have pinned their hopes on the ability of weed-eating fish to keep the weeds at bay while the corals recover following a major setback like bleaching, a dump of sediment from the land, or a violent cyclone.Read more
This behavior seems to imply a map sense from which the creatures read either absolute or relative location from at least two coordinates.
Direction is one thing but how about position?,
The results demonstrate for the first time that longitude can be encoded into the magnetic positioning system of a migratory animal.
Researchers from the Center for Marine and Environmental Studies (CMES) have reported on part of a scientific examination of deep coral ecosystems south of St Thomas and St John, an area known as the southeastern Puerto Rican Shelf.Read more
The Coral Proto Free Ocean Carbon Enrichment (CP-FOCE) system was designed to add low pH water into experimental chambers on the reef to stimulate pH levels predicted to occur on coral reefs in the next 50-100 years.Read more
Beluga sturgeon populations have been decimated in part due to unrelenting exploitation for black caviar —the sturgeon's unfertilized eggs—considered the finest in the world.Read more
Until the 1990s, only two kinds of orcas were seen in the inshore waters of British Columbia, says John Ford, a zoologist at the University of British Columbia and a research scientist at the Pacific Biological Station run by Fisheries and OceansRead more
