There was little information about the interactions between Patera binneyana and other animals; however since many terrestrial snails are similar we will be talking about the interactions of the general population of terrestrial snails.  

Terrestrial snails as Ken Hotopp had stated would be located towards the end of the food chain because of their small size and slow locomotion. There are abundant amounts of different types of invertebrate and vertebrate predators towards terrestrial snails (Hotopp, 2005). One in particular is Schaphinotus, a group of beetles that target snails and because of their smaller upper body portions they are able to enter into the snails’ shell (Dourson, 2006), but depending on the size of their prey and their own capabilities the ways that they hunt are different (Hotopp, 2005). If we look at the ruffed grouse they are able to swallow larger snails as a whole without breaking into the shell, compared to Haplotrema convacum, a predatory land snail, that breaks into the shell of its prey (Hotopp, 2005). However, though terrestrial snails are small, they have been able to develop multiple defense mechanisms to protect themselves.  

A defense mechanism that is used is increasing the amount of mucus made by terrestrial snails (Hotopp, 2005). Though the mucous is mainly used for locomotion and moisture, when a snail comes under attack they will increase the amount of mucous to stop the predator from attacking (Hotopp, 2005). Another mechanism is the coloration of the snails themselves. The colors of their shells are able to aid them in hiding in their environment from predators who hunt using vision (Hotopp, 2005).
