Museums hold 284 specimens collected within 10 miles of Sentinel between 1872 and 1975: 259 Animalia, 15 Plantae, 10 Fungi. 12 distinct Species records are shown. Collected by Armbruster, D. C. (Daniel C.), Athearn, Herbert D., Bogue, E.E. and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
