Abstract

Investigating Anodonta cygnea, Mytilus galloprovincialis, Venerupis decussata, Tapes decussatus, Peden Jacobaeus, Murex trunculus, Aplysia limacina and Odopus vulgaris it has been established that those species are able to endure prolonged anoxia the nervous system and other tissues of which contain large amounts of lipochrome pigment localized in the cytosomes. Using an electronmicroscopic histochemical method it was shown that the energy production of oxidative character persists in mitochondria and mainly in the cytosomes of the nerve cells even during the prolonged anoxia. As far as the mechanism of this process is concerned, it seems likely that the lipochrome pigment substitutes the molecular oxygen as electronacceptor. On the basis of this hypothesis one can explain many problems of the anaerobiosis.
