Gustav Paulay and I have started a project on iNaturalist for echinoderms (http://www.inaturalist.org/projects/echinoderms
iNaturalist is a website that allows users to submit images of the
species they encounter along with geographical location and any other
information about the observation (time of the day, depth, etc.). The
community can discuss and validate the identity of the species observed.
The project aims at improving our knowledge of all echinoderm species
worldwide. Join us and submit your photos to the project. Feel free to
contact me ([log in to unmask]
) with any questions.
