We now have two modi in PlanktonID. The already well-known puzzle mode and a new sorting mode. In the puzzle mode we discern 8 rhizaria categories and 3 further Zooplankton categories. In the sorting mode - which is available after 1000 images were validated in the puzzle mode - we discern 16 further categories that include different plankton organisms, fish, different particle classes and some image artifacts.
