The county history of 1912 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 110 specimens collected within 10 miles of Plankton between 1932 and 1969: 107 Animalia, 3 Plantae. 12 distinct Species records are shown. Collected by H. Price, Leslie L Pontius; Floyd Bartley, P. Bartholomew 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.
