(7) We have begun the study of the molecular and cell biology of embryos, larvae and recruits having as a final goal, the development of appropriate biotechnologies to rear this gastropod.
(8) The marine gastropods Acmaea (Collisella) limatula and Acmaea (Notoacmea) scutum respond to distant predatory starfish (i.e.
(9) Immunocytochemical methods using an antiserum raised against ovine corticoliberin revealed perikarya and processes in the central and peripheral nervous system of the Pulmonate Gastropod Helix pomatia.
(10) The distribution of monoamines in the central ganglia of the nudibranch gastropod Hermissenda crassicornis was examined through the histological localization of both glyoxylic acid-induced fluorescence and serotonin-like immunoreactivity.
(11) The hemocyanins of the Fissurellidae, Naticidae and Melongenidae families of marine gastropods as well as some other molluscs including some members of the Opistobranchia and Bivalvia groups have hemocyanins which exist in solution as tri-decameric and mixed, multi-decameric aggregates characterized by sedimentation coefficients close to 100 S, 130 S, 150 S, 170 S and 200 S to 230 S. 2.
(12) The accumulation of cadmium, zinc and copper by the marine gastropod molluscs Patella vulgata and Patella intermedia has been studied by gel permeation chromatography of water-soluble extracts of environmentally contaminated shellfish.
(13) The effect of antipsychotic drugs was tested on responses to micro-electrophoretically applied dopamine, acetylcholine and 5-hydroxytryptamine in identified neurons of the marine gastropod Aplysia californica.
(14) The distribution of FMRFamide-like material in the gastropod mollusc, Helix aspersa, was studied by radioimmunoassay (RIA) and immunocytochemistry.

(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.
