Nemertea (unsegmented worms) totop  
Dinonemertes shinkaii


Kajihara, H., and D. J. Lindsay, (2010), Dinonemertes shinkaii sp. nov., (Nemertea: Hoplonemertea: Polystilifera: Pelagica) a new species of bathypelagic nemertean: Zootaxa, v. 2429, p. 43–51.


A new species of bathypelagic polystiliferous nemertean Dinonemertes shinkaii is described based on the holotype obtained by the manned submersible Shinkai 6500 from a depth of 2343 m in Japan Trench, Northwest Pacific. Dinonemertes shinkaii can be distinguished from its congeners in having a translucent body, 24 proboscis nerves, two pairs of intestinal caecal diverticula, and about 25 pairs of intestinal lateral diverticula. This species represents the first dinonemertid to have pseudostriated muscle fibres in the rhynchocoel circular muscle layers.



Polychaete (segmented worms)totop  
squid polychaete


The ‘squidworm’ was collected in the Celebes Sea, at about 2800 m depth, using the “Global Explorer” ROV in September 2007.  It is considered a new genus and species, in a newly described family of swimming polychaetes (Osborn et al. 2009, Science 325:964).

Abstract: Kochimysis pillaii, a new genus and species of Heteromysini collected from the backwater of Kochi, is described. The new genus is closely related to the genus Deltamysis but is distinguishable from the latter by the following characters: antennules of male have a small setiferous lobe; antennal scale is without distal suture; second segment of mandibular palp broad; endopodite segments of maxilla subequal in length; in male carpus and propodus of second thoracic endopod with notches on outer margin; outer pair of apical spines on telson longer than the inner pair.
