An interactive identification key to species of the kinorhynch orders Kentrorhagata, Xenosomata, and Anomoirhaga

A new interactive DELTA key (DEscription Language for TAxonomy) for identification of kinorhynch species is made available. The key covers species of Kentrorhagata, Xenosomata, and Anomoirhaga, i.e., all non-Echinoderidae and non-Pycnophyidae kinorhynchs. Upon publication, the key includes 64 entries, but it will continuously be updated and expanded as new species are described. The present short note describes how to access key database, and how to use the identification tools.
