While Dr King is giving the guests the 'tour' through his greenhouse, he describes the design as being modeled after Buckminster Fuller's geodesic dome. However, there are no geodesic forms showing, just the simple metal lattice style of roof.
During his presentation at the 20 minute mark Dr. King mentions that nobody has any idea how long sharks even live. We do in fact know how long sharks live based on bone samples and examples of sharks in captivity. Hammerheads per example live roughly 30 years. Though Great White Sharks were considered about the same, some cases have shown them to live as long as 73 years.
