A quantitative model for the adhesive locomotion of the terrestrial slug, Ariolimax
The coastal Oregonian Province has a low-diversity fauna typically, with bradybaenid Monadenia fidelis and such genera as Vespericola, Haplotrema, Ancotrema, Hemphillia, Ariolimax
, Allogona, Cryptomastix, and Prophysaon characteristic.
First, Denny (1980) vividly demonstrates the important contribution of mucus production to overall locomotion costs in the terrestrial gastropod, Ariolimax
columbianus, and this per unit distance cost scales directly with speed.
This hypothesis might be addressed by measurements of oxygen consumption in snails using each gait, as has previously been done for adhesive crawling in the slug Ariolimax
columbianus Gould, 1851 (Denny, 1980a).
