Valerie and Ron Taylor didn’t always have an easy go of it with the scientific community. While Valerie kept detailed diaries of their observations, their work was often derided as too popular and showy. 

But science came calling when they needed someone to field-test their most recent theory. From diving gear to spear tips and shark tags, the Taylors gave it a shot and reported whether it worked – or not. 

Today, their scientific legacy is more highly regarded. Researchers are now using the Taylors’ footage to show environmental change and species loss over time.
