A new study, published in the Journal of Heredity, focused on groups of bottlenose dolphins that...

Bizarre Whale Strandings Not Due To Family Ties
2013-03-15 09:10:25

April Flowers for redOrbit.com - Your Universe Online Since the time of Aristotle, biologists have struggled to understand the reasons for mass strandings of whales and dolphins on beaches.

The findings...

Leader-follower Dolphin Pairs More Likely To Be Related Than Unrelated
