Undescribed marine taxa
Certain known types of marine organisms are of undescribed species, but can only be recorded in iNaturalist from the taxonomic backbone, usually based on the World Register of Marine Species (WoRMS). This project was started to document these types with their informal or phrase name used in the Observation Field as Undescribed working species.
