Crowdsourcing services allow employing human intelligence in tasks that are difficult to accomplish with computers such as image tagging and data collection. At a relatively low monetary cost and through web interfaces such as Amazon’s Mechanical Turk (AMT), humans can act as a computational operator in large systems. Recent work has been conducted to build database management systems that can harness the crowd power in database operators, such as sort, join, count, etc. The fundamental problem of indexing within crowdsourced databases has not been studied.

This review is based on the most recent taxonomic classification of extant Cuban Crinoidea. Existing material in natural history collections in Cuba was analyzed in detail and accurately reflects species presence. The crinoid literature was also reviewed. Several previously unpublished observations of species found in waters off Cuba have also been included. This paper provides the most up to date description of the Cuban crinoid fauna. Habitat, distribution, depth range and localities in Cuba are reported for each species. Collection codes for available specimens are included when known. The work describes a total of 33 species (plus two subspecies) in …
