The freediving champions of the dolphin world

Tue, 17 Jul 2018 09:48:04 EDT ~ New research explains how some populations of bottlenose dolphins can dive to almost 1,000 meters while avoiding decompression sickness. The new hypothesis suggests that lung architecture and the management of blood flow allow bottlenose dolphins to access oxygen in the lungs while preventing uptake of nitrogen which would cause the bends. The findings act as a starting point to understand how environmental changes and anthropogenic interaction may impact the future of the species. Find out more...

In male dolphin alliances, 'everybody knows your name'

Thu, 07 Jun 2018 11:27:56 EDT ~ It's not uncommon in dolphin society for males to form long-lasting alliances with other males, sometimes for decades. Now, after studying bottlenose dolphins in Shark Bay, Australia, for more than 30 years, researchers find that these males retain individual vocal labels rather than sharing a common call with their cooperative partners.
