i dunno if youve done it before, but what about Cambarellus Diminutus, AKA the least crayfish. Its the smallest crayfish out there with males reaching only 2.5cm and females getting up to 4cm at times, usually only around 3 though.

I love crawdads, thank you for the request!

Cambarid Crayfishes (Genus Cambarus), taken June 30, 2024, in Georgia, US

Assorted crayfish faces! These are both most likely Variable Crayfishes (Cambarus latimanus), though I do not know anything about crayfish ID so I don't want to assume anything lol. As it warms up I plan to spend more time catching salamanders and crayfish, though it can be a bit painstaking if they're smart. Once i got them into the container I was using for photos, I had to use a stick to gently push them to the edge to get my macro lens close enough. They behaved well, but it took forever!

Uncharismatic Fact of the Day

Chemical cues are an important part of communication for many animals, but the rusty crayfish takes it in an unusual direction. When individuals encounter each other, they use odors from urine to determine how to react. The stronger the cue, the less aggressive they are during the ensuing fight. A victorious male will also recognize the urine of a previously defeated opponent and will display dominance before attacking.
