Apart from that nemertean anatomy is marked by characters that are arguably plesiomorphic for Spiralia (Turbeville 2002). These include a largely compact arrangement of the tissue; a medullary cord type organization of the nervous system; a body wall muscle tube comprising minimally two, an outer...
Figure 2. The anatomy of a Nemertean is shown. Watch the video below to see a nemertean attack a polychaete with its proboscis. Digestive System The nemertini show a very well-developed digestive system. A mouth opening that is ventral to the rhynchocoel leads into the foregut, followed by...

The anatomy of the species is compared and contrasted with that of the other known members of the genus, Callinera buergeri Bcrgcndal and C. buergeri f. grandis Bergendal, from Scandinavian waters; f. grandis is afforded separate specific status as C. grandis Bcrgcndal....
Data detailing its internal morphology and external anatomy, and digital photographs are included. In addition, sequences of the ribosomal gene 28S and the mitochondrial gene cytochrome oxidase I (CO1) were obtained. These sequences were used in a phylogenetic analysis to test its phylogenetic ...
The anatomy of the monostiliferous hoplonemertean, Nemertopsis actinophila B眉rger, 1904, is described in detail and illustrated for the first time. The systematic position of the species is reassessed and a new genus, Cryptonemertes, is established for it. I concluded on the basis of ...
A new species of Carcinonemertes, C. pinnotheridophila, is described and illustrated. The worms were found in the pinnotherid crab Pinnixa chaetopterana collected from the coasts of New Jersey, North Carolina and Florida. The anatomy of the new species is compared and contrasted with that ...
