New Crabs for a New Year

Happy 2020 to all the members of Crabs of the World! For the new year, we have a new banner image, a splendid Trapezia rufopunctata photographed in Fiji by Mark Rosenstein (@maractwin). We now have 1326 crab species, thanks to observations by 474 amazing scuba divers, photographers, scientists, and explorers of tide pools. Below are links to six spectacular new crabs in the project, and then a few unusual crab observations, and also a question at the end of this post. I hope you will all continue to add crabs and friends to this project.

New project icon, four new species, and some remarkable crabs!

Every few months I like to highlight special additions to "Crabs of the World." This time, we have a new icon, the crab in the box at the lower left, Charybdis hawaiensis (Hawaiian Swimming Crab) with thanks to @davidr. You'll also see four crabs never previously observed on iNaturalist, and a few more extraordinary observations. When I started this project three and a half years ago, I never imagined we would pass my goal of 1,000 species of crab. And now we have 1,289, an increase of 34 in just three months. Congratulations and thank you to our 460 members who include outstanding scuba divers, marine biologists, photographers, and beach walkers.

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:

Celebration of Second Anniversary of "Crabs of the World!"

Thank you, fellow crab enthusiasts, for your participation in this project. In celebration of the second anniversary of “Crabs of the World,” I’d like to share some of my favorites from recent months, and recognize the 325 contributions of one member of the project. We now have a total of 910 crab species, 304 members, and 11,105 observations. Our goal is 1,000 crab species!

First, a fascinating video of filter feeding by Petrolisthses:
https://www.inaturalist.org/observations/9087164 tony_wills NZ video

Our first crab sighting in North Korea:
https://www.inaturalist.org/observations/10700958 amarzee

Amazing vampire crabs, mostly Ondrej’s:

A dozen interesting and/or stunning posts by global members of “Crabs of the World:”

And finally a spotlight on budak, whose day job is being a freelance editor based in Singapore. In his spare time he joins intertidal surveys— http://wildsingapore.com/— to coasts and islands in the area (to document their biodiversity, for public outreach/communication and also to make a case for their protection against land reclamation etc). Not a diver, all budak’s surveys are 'above water' on mudflats, mangroves, seagrass beds, coral flats and patch reefs during low spring tides, which occur 3-4 days a month (before dawn or after dusk). He says the crabs he commonly finds are the small hairy crabs (pilumnids), arboreal (sesarmids), moon crabs (Matutidae) and swimming crabs (portunids), but also reef crabs (xanthids) and spider crabs (majids), and sometimes rarer sponge crabs (Dromiidae), elbow crabs, pebble crabs, ghost crabs etc. Thank you, budak, for all your contributions to support Crabs of the World!

Update after 18 months of "Crabs of the World"

Just a note of appreciation to all the 219 members of "Crabs of the World." We've now reached our year-and-a-half anniversary of this project, and have increased the species in six months from 545 to 735. I never thought that would be possible! Recently people have posted photos of unusual and beautiful crabs from southern Africa, Thailand, and Alaska that have never been on iNaturalist before. I hope you have a chance to scroll through them all. And if you are an expert in crabs in one part of the world, there are many that still need identification. Whenever you post a crab observation, it's helpful to add it to the project, and also helpful to do that when you see a crab posted by someone else. Thank you!

First Anniversary of Crabs of the World

Greetings crabbers of the world,
Thanks to all of you--scuba divers on remote islands, beachcombers, hikers, and other intrepid naturalists with cameras-- we have 545 species of crabs on the first anniversary of this project. Many are quite unusual animals, and we now have crab observations from all over the world. I really appreciate how some of our 145 members have added other people's observations to this project. Thank you! If anyone would like to share interesting crab information, please let me know, as I occasionally post news about our project. Here where I live on the Olympic Peninsula on the farthest northwest corner of the continental United States, I'm involved in a crab project you may be interested in. For the second year I'm volunteering with a small team setting out traps and examining molts to search for the European Green Crab, Carcinus maenas. Sadly this highly invasive species has arrived in Puget Sound, not far from where we're searching. If you'd like to learn more, here's the link: https://wsg.washington.edu/crabteam/
Congratulations on helping build a rather special project with Crabs of the World!
