Description

sea otters and Indo-Pacific bottlenose dolphins share an ecological achievement: Both species use tools. dolphins carry cone-shaped sponges to protect their snouts while looking for rock dwelling fish, and Otters crack open snails with rocks. Studies have suggested that tool-use behavior in the dolphins may be inherited. Biologist Katherine Ralls and her colleagues looked for a similar pattern in otters off the California coast. The team tracked diet and tool use in the wild. It also analyzed DNA from 197 individual otters. Otters that ate many hard-shelled snails – and used tools most frequently — rarely shared a common pattern in mitochondrial DNA. Unlike dolphins, it was found modern otters only take up tools when their diet requires them.https://www.sciencenews.org/blog/scie...http://www.wochit.comThis video was produced by YT Wochit News using http://wochit.com
