At first, I thought this was a drawing of a crayfish. But, the gammarus pulex is quite small, only 21mm long, and is found in Europe; not the southeastern United States. But, like their American doppelgänger, they are also a crustacean found in fresh water.
This cute little fellow is from In sloot en plas, a Dutch language book by Eli Heimans and Jac. P. Thijsse in 1920. It’s a fairly well-detailed black and white drawing of this lobster and crawdad-looking creature.
Ironically, the drawing of this little guy is far larger than he is in real life. If you would like to access the larger image, simply click on the gammarus pulex picture above.
