So, there have been posts celebrating the milestones of 1/3 of vertebrates being on INaturalist, and then another post celebrating the milestone of 1/2. But then I wondered, what percent of arthropods have been observed on INaturalist? And so I carried out my investigation. I took total species coun…

Very informative and nicely done! The amount of species we have yet to observe is certainly a lot more than I expected, which I am sure is caused by high biodiversity in the more remote places of Earth. Thanks for the info!

It’s also proof that carcinologists need to get moving!

[image] Here is arthropod classes as a whole, compared to each other and to vertebrates. Something interesting to note is that, despite insects being so much more specious than other arthropod classes, they are also better sampled too. Around 16% of total insect species have at least one research …

I moved the above four posts to this topic and reopened to keep all the discussion together.

I didn’t even know that was possible, but thanks I guess

If you ever want to open an old thread, you can request from a specific mod or just mention forum_moderators.

Anyway, we compared arthropods to vertebrates, and arthropods to each other. How does the rest of the animal kingdom stack up? I did it mostly by phylum, but I aggregated some smaller related phyla into larger groups. Scalidophora: Kinorhyncha, Loricifera, Priapulida Mesozoa: Rhombozoa, Orthonect…

[image] insectilluminatigetshrekt: Arthropods come in so many varied forms, and many look very “cool” or “cute”. But nematodes are just kinda bland, generic looking worms. On that note, if you were to look at Platyhelminths, I predict that you would find the observations heavily biased toward…

Yup. Most flatworms are either microscopic, or endoparasites. Geoplanids are the only ones people could ever reasonable come across

There are plenty of marine flatworms. They reach a respectable size and some of them are very colorful. They are not uncommon in the intertidal zone and on coral reefs.

How complete is Arthropoda on INaturalist?

Wouldnt most people who use inaturalist know what phyla are?
