Figure 12 shows measurements of photosynthetic activity plotted against starvation days. Data are shown in Table 7. Maximum quantum yield values (Φ IIe-max) on the day of collecting (but after several hours of starving) start on a higher level of 0.6 and decrease to around 0.5 after nine days of starving. No information on algal food or development is available yet.

are shell-less sacoglossans with a flattened body, with leaf like lateral expansions (parapodia), which are usually folded up on the dorsal side. The pericardium is located mediodorsally just behind the head. A number of pericardial vessels are found branching from the pericardium along the dorsal surface of the body and parapodia. Marcus d. B.-R. (1980) described the branching patterns of the vessels as species-specific. According to anatomical data, we include the new species to the genus, since the presence of blade-shaped radula teeth with a median denticulate cutting edge is confirmed, and no pharyngeal pouch was found. Molecular data also give evidence for this assignment.
