There is no shell. The tiny MOLLUSCA solenogasters have bristle-like spicules over Chitons, bivalves, sea snails, sea almost the whole body, a groove on the underside of the body, and no gills. The more worm-like slugs, octopus, squid, tusk shells caudofoveates have a groove and fewer spicules but have gills. There are 10 species, 8 undescribed.

Wilson1, J. Zhang3,15 and N. J. Bax2,16 Abstract Background: Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over the last 150 years. In May–June 2017, the IN2017_V03 expedition of the RV Investigator sampled LBA benthic communities along the lower slope and abyss of Australia’s eastern margin from off mid-Tasmania (42°S) to the Coral Sea (23°S), with particular emphasis on describing and analysing patterns of biodiversity that occur within a newly declared network of offshore marine parks. Methods: The study design was to deploy a 4 m (metal) beam trawl and Brenke sled to collect samples on soft sediment substrata at the target seafloor depths of 2500 and 4000 m at every 1.5 degrees of latitude along the western boundary of the Tasman Sea from 42° to 23°S, traversing seven Australian Marine Parks. -

Deep-Sea Life
Deep-Sea Life Issue 7, June 2016 Welcome to the seventh edition of Deep-Sea Life: an informal publication about current affairs in the world of deep-sea biology. Once again we have a wealth of contributions from our fellow colleagues to enjoy concerning their current projects, news, meetings, cruises, new publications and so on. The photo of the issue is of the handsome crew from NIWA, NZ (Mireille Consalvey, formerly NIWA, Malcolm Clark and Ashley Rowden), sporting their newly-published book – Biological Sampling in the Deep Sea (see article on page 43 for further details). This represents the first comprehensive compilation of deep-sea sampling methodologies for a range of habitats. It is hoped that the book will help to promote international consistency in sampling approaches and data collection, advance the integration of information into global databases and facilitate improved data analysis Above: Mireille Consalvey, Malcolm Clark and Ashley Rowden, with their and consequently uptake of science results for the new book “Biological Sampling in the Deep Sea” management and conversation of the deep sea. The management and sharing of valuable deep-sea biodiversity data is the subject of an upcoming funded workshop later this year run by OBIS & INDEEP which will train deep-sea scientists in data management, access and processing. This effort will be the beginnings of establishing a new deep-sea OBIS portal to connect with existing information systems such as WoRDDS (see page 26 for further details). I always appreciate feedback regarding any aspect of the publication, so that it may be improved as we go forward. -

Recent Cephalopoda Primary Types
Ver. 2 March 2017 RECENT CEPHALOPOD PRIMARY TYPE SPECIMENS: A SEARCHING TOOL Compiled by Michael J. Sweeney Introduction. This document was first initiated for my personal use as a means to easily find data associated with the ever growing number of Recent cephalopod primary types. (Secondary types (paratypes, etc) are not included due to the large number of specimens involved.) With the excellent resources of the National Museum of Natural History, Smithsonian Institution and the help of many colleagues, it grew in size and became a resource to share with others. Along the way, several papers were published that addressed some of the problems that were impeding research in cephalopod taxonomy. A common theme in each paper was the need to locate and examine types when publishing taxonomic descriptions; see Voss (1977:575), Okutani (2005:46), Norman and Hochberg (2005b:147). These publications gave me the impetus to revive the project and make it readily available. I would like to thank the many individuals who assisted me with their time and knowledge, especially Clyde Roper, Mike Vecchione, Eric Hochberg and Mandy Reid. Purpose. This document should be used as an aid for finding the location of types, type names, data, and their publication citation. It is not to be used as an authority in itself or to be cited as such. The lists below will change over time as more research is published and ambiguous names are resolved. It is only a search aid and data from this document should be independently verified prior to publication. My hope is that this document will make research easier and faster for the user.
