The expedition's professional scientists were the malacologist Henry A. Pilsbry and the ornithologists A. K. Fisher and Alexander Wetmore.
[3] Howard Cleaves documented the expedition with a motion picture film that was shown in movie theaters throughout the United States.
[6] Cornelia Bryce Pinchot gave free talks with showings of Cleaves's documentary film.
[7] Mordaunt Hall, a 1930s movie critic, wrote concerning Cleaves's film: There are amazing scenes of natives jumping into the crystal waters, harpoon in hand, to land on the backs of the enormous sea bats.
There are views of the San Bias Indians, of enormous land turtles, iguanas, sea tigers and Man-O'-War hawks.
[9]On Isla de Providencia, the expedition discovered a new lizard species, which Doris Cochran named Anolis pinchoti.
