Abstract:
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.
