Ultrastructure of the frontal organ in Convoluta and Macrostomum spp. : significance for models of the turbellarian archetype
Klauser MD, Smith JP, Tyler S. 1986. Ultrastructure of the frontal organ in Convoluta and Macrostomum spp. : significance for models of the turbellarian archetype. Hydrobiologia: The International Journal on Limnology and Marine Sciences. 132:47-52
'Present models of turbellarian evolution depict the organism with a frontal organ - a complex of glands whose necks emerge at the anterior tip of the body - and therefore imply that this organ is homologous throughout the Turbellaria. However, comparisons of representatives of the Acoela and Macrostomida, two putatively primitive orders of the Turbellaria, show that frontal organs in these two are not similar in ultrastructure or histochemistry.' INVERTEBRATES: Convoluta pulchra was collected from Mackerel Cove on Swan's Island and Macrostomum hystricinum marinum was collected from Hulls Cove for use in this study /STUDY LOCATIONS:/ /MOUNT DESERT ISLAND/Hulls Cove/ISLANDS/Swans Island
