TED Video by Richard Pyle from 2004

TED stands for Technology, Entertainment and Design. It is a nonprofit devoted to Ideas Worth Spreading and its website has over 900 “TEDTalks” available online for free, from a wide variety of presenters.

Richard Pyle is a self-proclaimed fish-nerd. He is also a highly accomplished deep diver, who gave his name to “Pyle stops”, or deep water stops.  In 2004 he gave a talk on diving the reef’s twilight zone. This is the part of the reef wall beyond most recreational scuba divers, in the 60 – 150 metre range. The video includes a quick introduction to the effects of depth on divers, as well as Closed Circuit Rebreathers, before turning to the wide range of new species of fish that exist in that depth range. Throughout the talk you can hear his passion and enthusiasm, and it is well worth watching and is on TED’s website.
