Hemoglobin content in radular muscle and relative weight of the main viscera were determined in Aplysia dactylomela. We propose that relatively low concentration of tissue hemoglobin as well as low heart and ctenidium indices are due to the mode of the mollusk nutrition. Nutrition by biting algae fragments requires less muscular effort than, for instance, scrapping off overgrowth from substrate and, hence, is accompanied by lower indices.
测定了指状背肛海兔齿舌肌中的血红蛋白含量以及主要内脏的相对重量。我们认为，组织血红蛋白浓度相对较低以及心脏和鳃指数较低是由于软体动物的营养方式所致。与例如从基质上刮除附生植物相比，咬食藻类碎片所需的肌肉力量较小，因此，其相关指数也较低。
