(16) Previous research suggests that gut distension by ingested bulk plays an important role in the regulation of food intake in gastropod molluscs.
(17) Hemocytes taken from six different gastropod snails, Achatina achatina, A. fulica, Biomphalaria glabrata, Bulinus natalensis, Helix aspersa, and Lymnaea stagnalis, were compared for morphology, peroxidase activity, and, using methods developed for L. stagnalis, the ability to generate reactive oxygen inermediates upon phagocytic stimulation.
(18) The total amount of retinochrome in the retina was several times higher than that of rhodopsin, distinguishing the gastropod eye from the cephalopod eye.
(19) Among the known intermediate filament proteins, NF60 and NF70 neurofilament proteins show highest similarity to an epithelial intermediate filament protein from Helix pomatia, a gastropod mollusk, and are less similar to vertebrate neurofilaments.

Definition:
(n.) A genus of marine gastropods, having rough, and frequently spinose, shells, which are often highly colored inside; the rock shells. They abound in tropical seas.
