Interactions
Terrestrial
snails have many interactions with other animals. These animals
may include other species of snail, predators, and prey. In some
snail species interaction with another snail may mean being a
predator, or worse prey. Terrestrial snails may be carnivorous
and prey on other snails, however some land snails only interact
with other snails in order to reproduce.
Snails also become prey to parasites. Many parasites use snails
as an intermediate host. These parasites include nematodes and
mites.
There are vertebrates that prey on land snails as well. Some
kinds of vertebrates that prey on terrestrial snails include
turtles, mice, and turkeys. Even humans are a predator of
snails. Humans harvest snails in order to eat their visceral
mass (Hotopp, 2005).
