Phylum Mollusca Class Bivalvia Heterodonta Marine organisms. 1) Cardium, lateral view of the general anatomy, after removal of left valve: heterodont valve (6, 7). One can see well the wide mantle with two siphons, the incurrent and the excurrent one, in the posterior end; the eulamellibranch ctenidium; dorsal heart; digestive system with stomach and digestive gland; gonad; two valve adductor muscles; the red foot. 2) View from the dorsal portion of the pericardial cavity. 3) Schematic representation of the internal anatomy of Teredo. 4) Teredo, a bivalve that burrows in wood: a small shell and two siphons are visible. 5) Initial bivalve veliger larva.Tavola LXXXIX Tavola parietale.
