Nutrition
The food habits of Magazine Mountain shagreen is similar
to most other Polygirids and is described as "general" (Caldwell
et al. 2009). This means they use any sort of leaf litter,
decaying logs or branches, and occasionally dead animals as both
a food source and a means of
shelter. The key factor that determines whether they venture out
of the talus slope to feed is the temperature. The south and
North slope of Magazine Mountain are comparable in vegetation
and landscape, but the north side is an average 2.9 degrees
cooler and receives more rainfall; hence the reason for the
snail only being found on that side of the mountain (Caldwell
et al. 2009).
In terms of internal nutrient transportation and circulatory system, Shagreen is again like most Polygirids in that it uses an open circulatory system that allows hemolymph to flow over internal organs. The problem of fouling is also present torsion pulls the anus into a position near the head (Caldwell et al. 2009). Although there may not be many documented cases or studies of this snail, it is very comparable to other land snails in regards to its feeding and internail nutrition methods.
