Deep Sea ID App

The first version of Deep Sea ID, an iOS field guide app to the marine life of the deep sea, was released in March 2014.  This app is now available both for iphone and ipad and for android from the app store.  The app has already been downloaded over 35,000 times (as of December 2016) by users from many different countries.

The app is the result of a project funded by INDEEP and carried out by personnel from the Natural History Museum, the National Oceanography Centre and the World Register of Marine Species. It allows offline access to the World Register of Deep-Sea Species (WoRDSS) and currently stores on your device the taxonomic information for over 25,000 deep-sea species, over 500 high-resolution photographs of deep-sea specimens as well as links to online taxonomic tools, sources and important references.

The app is designed to improve access to taxonomic information for researchers and contractors working at sea or in the laboratory as well as educators and science communicators who wish to learn more about the remarkable diversity of deep-sea life. The app will be regularly updated with more images, and we welcome contributions (see below). All photographs include full credit and contact details and authors retain copyright.

For further information on the criteria we have used for inclusion in the database, please read the information on the WoRDSS homepage.


Data Sources & Acknowledgements

The taxonomic information held in the World Register of Deep-Sea Species (WoRDSS) is sourced directly from theWorld Register of Marine Species (WoRMS). WoRMS is managed by an international Steering Committee, a Board of Editors and the IT team at the Flanders Marine Institute (VLIZ) in Belgium. Both the WoRMS and WoRDSS websites are hosted at VLIZ. 

The species lists and images that are used to create Deep Sea ID are currently maintained at the Natural History Museum in London, UK by Dr Adrian Glover and at the University of Plymouth, UK by Dr Nicholas Higgs. At theNational Oceanography Centre, Southampton, UK, Dr Tammy Horton is contributing to the species lists and coordinating the collation of taxonomic identification resources. 

Deep Sea ID has been developed by the Natural History Museum, London with the iOS software development by Heathwest Systems Ltd.

Contributing Images and Correcting Errors: We are continuously sourcing more images for future versions of the app. Please consider contributing! We also welcome contributions and corrections to the main database. Further information including details on how to contribute new images are available on the WoRDSS website. Please contact us with any questions.


WoRDSS - World Register of Deep-Sea Species

WoRDSS is a taxonomic database of deep-sea species based on the World Register of Marine Species (WoRMS). This site was launched in December 2012 as a project of INDEEP. The primary goal of the project is to build a comprehensive database of known deep-sea species and to present this as a thematic species database (TSD) of WoRMS, with all data dynamically linked to WoRMS and their team of taxonomic editors. A secondary goal is to accumulate high quality specimen images of deep-sea species and to present these on both the website and the iOS app (mentioned above) that allows offline-viewing of the complete database and imagery to assist with identifications at sea and in the laboratory. Through WoRDSS, we are also providing taxonomic references (sources) that will allow researchers and educators easier access to identification literature.

The WoRDSS project provides an open-access source of quality taxonomic information and imagery on deep-sea species and at the same time enhances the WoRMS database through the provision of images, new soures and editorship. Contributions and corrections are welcome.

Three successful projects addressing gaps in WoRDSS (Asellote Isopoda, Holothuroidea & Polychaeta) were undertaken in 2014.  The LifeWatch fund and INDEEP financially supported these projects which together have added 30 newly published species to WoRMS, added 1391 new deep-sea distributions to WoRDSS, linked or added over 122 identification references and made available 74 good quality images for use on WoRDSS and the iOS app.  In 2016, a further LifeWatch grant funded work on the addition of new information and data for the amphipoda.

Special Session "Evolution in the Deep Sea: Origins, Adaptation and Diversity".

This INDEEP special session was held in China in October 2014 in conjunction with the World Conference on Marine Biodiversity and brought together a new inter-disciplinary group of scientists to explore how life evolved in the deep and the remarkable adaptations of deep-sea animals.  The session attracted 14 oral presentations and a wide audience. 

List of deep-sea taxonomic experts

An increasingly comprehensive listing of deep-sea taxonomic experts has been produced and is continually updated by Dr Tammy Horton and Dr Maria Baker.  It is available on our INDEEP resources page.
