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...
