Reproduction
Due to the extreme scarcity of individuals and population range, not much is known about the reproductive processes or the life history of Inflectarius magazinensis. However, after a survey of species in 1986 by Dr. Robert Caldwell, a bit of insight was given into the potential developmental processes of the species. Though Dr. Caldwell spent extensive hours or research in both the lab and field, there were only thirteen eggs discovered that belonged to Magazine Mountain Shagreen (Caldwell et al. 2009). The average diameter of eggs was 2.7mm and of the thirteen collected, only ten of them had hatched after a five week incubation period (Caldwell et al. 2009).
The limitation of egg discovery, Dr. Caldwell hypothesized that the majority of the time eggs are deposited deep within the talus slopes that the snail inhabit (U.S. Fish and Wildlife Service, 1994). A talus slope is defined as the area where the majority of accumulated rock debris is deposited at the base of a steep slope following a mass movement event (i.e. rockfall)(Merriam Webster's).
