The Occurrence and Significance of Endosymbiotic Chloroplasts in the Digestive Glands of Herbivorous Opisthobranchs(1).

Intact algal chloroplasts have been found in the digestive glands of 5 species of Opisthobranchia belonging to the order Saccoglossa. Preliminary studies on 3 of these confirm their endosymbiotic nature. It is suggested that the occurrence of these endosymbiotic organelles may be widespread among related species of Saccoglossa. Their independent functional… CONTINUE READING
