Handy guides!

Ooh, you can get it on a t-shirt or a mug or a whole bunch of things!

And she’s got one for arachnids!

Now if only there were a similar poster for all the spider families — there are 117 of them, last I looked. I tell you, the World Spider Catalog is not the place to start studying their taxonomy.

    Both are great but if I was going for a T-shirt, I’d go for the arachnid. I feel a bit more kinship with them.

    Oops, got to run, there was a tug on line 71.

    Speaking of cephalopod pedantry – the following concerns Finnish language but I suspect also German and several German-infuenced languages.

    We usually use the collective name that is literally “ink fish” for coleoid cephalopods, which includes all currently living forms except the nautiloids. This results in some translation mismatch with English, since many people don’t know there are specific local names for octopus, squid, cuttlefish etc. Many people also don’t know their local equivalent term for “cephalopod” or “nautilus”.

    Im lost. The top illustration first makes the point that Arms are NOT Tentacles, but then with octopoda it sais 8 arms, 8 tentacles, leaving me to wonder how to read the numbers correctly? #dumbQuestion?

    I remember the first time I saw a book scorpion. It was actually in a book. I was reading outside so I assumed I’d picked it up there. It was about two millimetres long, and have very large (for its size), obvious scorpion claws, but no tail. I was fascinated, but none of my books had anything to help me identify it. This was shortly before the Internet was commonly available.

    The inclusion of the belemnoid led me to something I hadn’t known previously: there are some highly complete body fossils for them, showing all manner of soft parts. Cool.
