Summary

DescriptionArchimollusc-en.svg	English: Anatomical diagram of the hypothetical ancestral mollusc (“HAM”). Nervous system is hypoathroid. Unsegmented, bilaterally symmetrical body, organs occur either singly or in pairs (no metamerism), hemocoel circulatory system filled with hemocyanin, gametes ejected into pericardium and travel through nephridia to environment. Deutsch: Darstellung der Anatomie des „hypothetischen Urmollusks“ (engl. hypothetical ancestral mollusc, HAM), des hypothetischen gemeinsamen Vorfahren der schalentragenden Weichtiere (Conchifera). Das Nervensystem ist hypoathroid (d.h. Pleuralganglien und Pedalganglien liegen relativ weit entfernt von den Cerebralganglien – der primitive Zustand bei Mollusken). Der Körper ist unsegmentiert und prinzipiell bilateralsymmetrisch, Organe treten entweder paarig oder einzeln auf (keine Metamerie), Sauerstofftransport in der Hämolymphe erfolgt über Hämocyanin, die Gameten werden ins Perikard injeziert und über die Nephridien an die Umwelt abgegeben.
