Researchers suspect that the dolphins were playing with the boa, but many questions about the behavior remain

Biologists of the past often explained the vast spectrum of animal genitalia with "lock-and-key": the hypothesis that vaginas and penises had primarily evolved to fit into each other mechanically. Today, there is a growing appreciation for the myriad of forces acting on genitals.

Scientists once thought marine life kept quiet. Then the Navy tapped an aptly named researcher with an open mind

Dolphins can tolerate freshwater for short periods of time, but they developed painful lesions after the storms as a result of prolonged exposure.
