Crabs of the World

Happy 8th Anniversary of Crabs of the World! It’s amazing to scroll through all your crab observations that demonstrate such global diversity and beauty. Thanks so much to all 1,368 members for adding your observations to this project, as they’re not automatically added (and please remember: NO shrimp or crayfish).

We now have 2,318 species in this project, 20 more than my last post in March. Every few months I first focus on some species that are new to iNaturalist, and then others that are fabulous. Please notify me if yours is new, otherwise I probably won’t know!

Here are some of the new crab species; a few still need confirmation (can you help?):

•A Parvuspotamon yuxiense (Eurasian Freshwater Crab) by @swimkang in China:
