Lucilla inermis - Oldfield Coil

The Food Oldfield Coil Eats

In the Phylum Mullusca a majority of the animals feed by means of a radula. It is located at the base of the foot under the species head.  The radula has tiny teeth that scrape up the substrate they are feeding on. Lucilla radula has narrow tricuspid teeth and short central teeth (Pilsbry,1939-48).

The figure shows the process a snail goes through to use its radula. The radula moves in and out of the mouth to scrape food.

There are different types of feeding done by gastropods. Some graze for their food while others browser around. Many Pulmonates are commonly herbivores, but there are some who eat earthworms and other small snails (Hickman, 2009). Once food is attached to the radula the mouth opens; the food is then brought into the mouth via the radula moving backwards and moved to the pharynx. After the pharynx, the digestion order is very similar to every other animal. Food moves through the stomach, then the intestine where food gets absorbed, and then out the anus. Lastly, the Oldfield Coil has an open circulatory system. The blood is pumped by a heart and runs through a series of vessels called sinuses. There are only a few sinuses, otherwise the blood pools over the internal organs (Hickman, 2009). Since Lucilla inermis lives in dry soil, they may have difficultly retrieving food and nutrients if other organisms do not like dryness.


Lucilla inermis does not have any information currently accessible about its nutrition. Information about the types of food it eats is not known at the moment.
