Many Things Under a Rock

David Scheel, Professor of Marine Biology at Alaska Pacific University, has researched the behaviour and ecology of octopuses for more than 25 years. His discoveries include a previously unnoticed species of large octopus and a common signal use among octopuses living in unusual densities. He starred, with Heidi the Octopus and his daughter Laurel, in the BBC documentary 'The Octopus in My House'.
