In the pulmonate gastropods Lymnaea
stagnalis, Helix aspersa and Arion hortensis, the class to which Siphonaria also belongs, "pore cells" (recently renamed "rhogocytes", for review, see Haszprunar 1996) scattered among the connective tissue have been proposed as candidates for the site of hemocyanin biosynthesis (Sminia and Boer, 1973; Skelding and Newell, 1975; Sminia and Vlugt van Daalen, 1977).
There are various species of snail in Cross River State namely: Golden snail (Pomacea sp), African giant edible tropical land snail (Limicolaria aurora), Achatina fulica, Achatina achatina, Archachatina marginata, Limicolaria flammae, Lymnaea
natalensis, Bulinus forskalii,Bulinus globosus Biomphalaria pfeifferi and Freshwater snail (Lymnaea
acuminata) (Ebenso, 2002; Adinya, 2006).
A study of the amino acids present in Lymnaea
stagnalis, Planorbarius corneus and Australorbis glabratus before and after infection with Schistosoma mansoni.
Other groups that contributed low proportions to the total of collected organisms were odonats, dipterans, and mollusks from the genus Lymnaea
Interestingly, native receptors from the squid were more sensitive than the heterologously expressed GABARs of the pond snail Lymnaea
stagnalis (EC50 200-300 Amol [1.
Although we sampled all locations within the state of New York where the exotic snail Lymnaea
auricularia was previously reported, we did not find this species.
Van Elk and Joosse (1981) recorded the influence of the photoperiod, the starvation and the infection with larval trematodes on the catalytic activity of the enzyme UDP-galactose 4-epimerase in the albumen gland of Lymnaea
stagnalis Linnaeus, 1758.
tuberculata, however Monteiro and Dias (1980) found Lymnaea
The common ancestor of Limax and Lymnaea
was likely an inhabitant of the marginal area between aquatic and terrestrial zones (i.
In contrast to this, the pond snail Lymnaea
stagnalis has 11 ganglia: a pair of buccal ganglia, a pair of cerebral ganglia, a pair of pleural ganglia, a pair of parietal ganglia, a pair of pedal ganglia, and a visceral ganglion (Benjamin et al.
In fact, regenerated networks of neurons of the pond snails Lymnaea
and Helisoma exhibit patterns of activity (i.

peregra (Gastropoda: Pulmonata).
