Cladoceran curators - Cladocera are colloquially known as ‘water fleas’ globally. All Cladocera. Why then is Daphnia separated out as the designated ‘water flea’ on the drop down menu when a search for ‘water fleas’ is made? And when a posting of Simocephalus, for example is identified as Daphnia, and a correct ID is suggested, the corrector has to disagree that it is in fact a ‘water flea’ to get to the correct genus. It is a water flea, but isn’t Daphnia. Daphnia should be integrated into the ‘Clam Shrimps and water fleas’ category, removed from the separate drop-down box, and thereby restore equanimity!
Welcome to the iNat Forum! Since this post seems to be about a common name issue for a specific taxon, it would be better discussed as a taxon flag on Cladocera (assuming you are talking about Diplostraca) on iNaturalist itself. You can mention some top observers/IDers of cladocerans on the flag to request input. “Water Fleas” is already entered as a common name of Diplostraca, so I’m not sure that there’s much else to do. It is listed above Daphnia in the dropdown for Explore when "“water flea” is entered into the search.
One key point is that there isn’t any way to edit the dropdown options manually - these are generated programmatically. Daphnia correctly has “water flea” as a common name, so it is going to show up when people search for that name.
