Greg Marshall is an inventor, biologist, conservationist, and Emmy Award-winning filmmaker who has dedicated his life to studying, exploring, and documenting animal life in the oceans and across the globe.

Marshall’s most celebrated contribution to the research community is the invention of the National Geographic Crittercam, a small, lightweight, streamlined camera that has the remarkable ability to travel unobtrusively with its animal hosts where no camera has been before, capturing never before seen footage of the private lives of wild animals.

Marshall’s inspiration for Crittercam came during a diving expedition off Belize during which he encountered a large shark and a remora—a natural hitchhiker fish suckled to the shark’s side. Imagining the unique point of view of this tiny stowaway and the profound information such a perspective would provide for science and conservation, Marshall conceived a remote camera that would mimic the remora’s behavior—and the field of animal-borne imaging research was born. Marshall has since dedicated his life to researching the behavior of marine and terrestrial species across the globe, heading up over a hundred field expeditions worldwide and collaborating in cutting-edge behavioral studies of over 70 species, from lions to emperor penguins to humpback whales.

In addition to publishing with his collaborators in major journals, Marshall has through his Crittercam research provided a dazzling library of imagery from the perspective of animals in the wild. This footage has been used in over 70 National Geographic documentaries, including a 13-part National Geographic television series, numerous PBS/NBC/NGC specials, and 60 short films airing on PBS’s Wild Chronicles series.
