Mollusc
Definition:
(n.) Same as Mollusk.

(18) The bag cells of the marine mollusc Aplysia are well-characterized neuroendocrine cells that initiate egg laying, but the natural stimulus triggering bag-cell activity has not been determined.
(19) Immunochemically, the major common epitope expressed by the neutral fraction glycolipids of the 3 taeniid species is the same or very similar to the glycosphingolipid, neogalatriaosyl ceramide derived from the marine mollusc Turbo cornutus (Gal(beta 1-6) Gal(beta 1-6) Gal(beta 1-1)Cer).
(20) Pharmacologic activation of endogenous protein kinase C (PKC) together with elevation of the intracellular Ca2+ level was previously shown to cause reduction of two voltage-dependent K+ currents (IA and ICa2+-K+) across the soma membrane of the type B photoreceptor within the eye of the mollusc Hermissenda crassicornis.
Operculate
Definition:
(a.) Alt. of Operculated
Example Sentences:

(5) The miracidium develops and hatches in 11 to 14 days at 22 to 25 C. The operculate snail, Lithoglyphus virens, serves as first intermediate host.
(6) A diagnosis of hepatic fasciolasis was based on the finding of operculate eggs in duodenal juice obtained by duodenal aspiration.
(7) The small, dextral, operculate snail G. australis was identified as the intermediate host and G. australis and an unidentified planorbid as transport hosts.
