Abstract

The spermatozoa of Octopus dofleini martini produce anaerobically D(—)-lactic acid and possess a very active D(—)-lactate dehydrogenase. In this respect, while resembling certain microorganisms, they differ strikingly from mammalian spermatozoa which produce L(+)-lactic acid and contain L(+)-lactate dehydrogenase.
