Congratulations and thank you to the 337 members of “Crabs of the World,” for documenting one thousand species of crabs around the world! We have met my original goal, and now aim for 1,500.

In this post, I’d also like to share a few links. Here are @mikegigliotti’s helpful notes on online crab resources, crab anatomy, and how to photograph a crab:
