Re: the last post, the article mentions that some places use clams to test the toxicity of the water. It’s like that in Warsaw- we get our water from the river, and the main water pump has 8 clams that have triggers attached to their shells. If the water gets too toxic, they close, and the triggers shut off the city water supply automatically.
The clams are just better at measuring the water quality than any man-made sensors.
They’re mostly underground, so you don’t have to draw anything. But for those who want to *actually* draw bivalves for #InsertAnInvert, @spissatella helped me prepare these cheat sheets!

#InsertAnInvert is a series of invertebrate drawing guides done in collaboration with actual experts (like, literal Dr. Crabs and Dr. Cephalopods and all that) so if you could give them a follow on twitter that’d be swell.
