Since there has been very little research done on Practicolella trimatris, there is very little known on the snails adaptations. 


The only known adaptation of Practicolella trimatris is the snail adopted a shell banding that helps camouflage the snails from several bird predators, while the snails climbed toward the top of vegetation (Perez, 2011).


To understand the adaptations of the snail, Practicolella trimatris, it is best to look at the family, Polygyridae. The Polygyridae adapted into becoming air-breathing land snails without the possession of a dart apparatus. (Encyclopedia of Life, 2012). Along with these adaptations, the Polygyridae family developed some absences of important features. They developed the absence of a diverticulum and the stimulatory organ (Binney, et. al., 1851). The diverticulum is an irregular pouch that projects from a hollow organ (Merriam-Webster, 2013).
