Only Six More Crab Species to Our Goal!

Greetings to all 1,324 members of Crabs of the World. Thanks for increasing our new total of 1,994 species, 36 more than on January 20. Every two to three months, I highlight some special observations. It's hard to choose! Our project goal is 2,000 species, and it’s exciting we only need SIX more! (Quick reminder— Everyone, please add your crab observations to this project, as they are not automatically added. Thank you so much to everyone who adds them.)

First, a focus on some species that are new to iNaturalist:

A purple and orange Freshwater Crab, Genus Sundathelphusa, possibly a yet to be described species, found by a waterfall at high elevation in The Philippines (wow!) by @albertkang:

@uwkwaj spent years at Kwajalein and Enewetak Atolls in the Marshall Islands documenting marine life. They have just joined our project and brought several amazing new species, including some that still need confirmation for “Research Grade” (can you help?):
Here’s one of their Etisus demani (Pale Pebble Crab):

And one of their Tylocarcinus styx (a Kelp Crab):
