With each molt, this Great Plains Mudbug (Lacunicambarus nebrascensis) becomes a bit more blue. In 2023, she was more of an olive brown.

Today, we share our love for federal fisheries professionals who work tirelessly to address the myriad problems facing our nation’s fisheries. We urge the Administration to stop indiscriminate mass firings and to build and maintain a sufficient federal natural resource workforce.

@Mikeropod Yes!

@Cray_Bay99 Hydrobiidae?

It is always an honor to see the smallest endangered species that is listed. The Tumbling Creek Cavesnail (Antrobia culveri) is found only in one cave and the largest adults tend to be around 2mm.

Sculpins love to get themselves into weird places. This Knobfin Sculpin thought an EXO2 sonde was the perfect place to reside in.

Raise your chelae for #CrayWeek The best week of the year! 🦞🎆 Pictured: Freckled Crayfish (Cambarus maculatus)

Took a bit more effort to get this Grassland Crayfish (Procambarus gracilis) out of her burrow!

Extremely grateful to be given the opportunity to sample Smallin Cave for Bristly Cave Crayfish (Cambarus setosus). Beautiful cave system!

Been helping out with freshwater snail identification. Here's one out of its shell. 🐌 Species: Pyramid Elimia (Elimia potosiensis)

Interested in working in the Ozarks of Missouri this summer surveying rare fishes? @MDC_online is currently accepting applications online at the link below jobs.mdc.mo.gov/job/Columbia-R…

I loved helping out with this project. Huge thank you to USFWS for choosing to showcase Missouri's crayfish 🦞❤ youtube.com/playlist?list=…

Always a great day when you're working in caves! Had fun collecting genetic samples from Bristly Cave Crayfish (Cambarus setosus) 🦞

The Hubb's Crayfish (Cambarus hubbsi) has a limited range in the Ozarks of southern Missouri and northern Arkansas. A beautiful crayfish that is rarely seen as they tend to spend most of their time underneath large substrate.

Worst pinch award goes to Hubb's Crayfish (Cambarus hubbsi) 🙃🦞

@DrCrayfish I bought the large one and I was so excited about it that the vendor gave me the small one for free!

@Cray_Bay99 Hope you bought them!!! 😍

You never know what you will find at a flea market! 🦞❤

Every week is #CrayWeek for me 🦞❤ Pictured: Golden Crayfish (Faxonius luteus), Caney Mountain Cave Crayfish (Orconectes stygocaneyi), Freckled Crayfish (Cambarus maculatus), Painted Devil Crayfish (Lacunicambarus ludovicianus)

Fact: Crayfish are cute. #CrayWeek Took this picture of a Great Plains Mudbug (Lacunicambarus nebrascensis) while she was crawling around trying to find her burrow.

My favorite crayfish species, the Freckled Crayfish (Cambarus maculatus). Endemic to the Meramec River basin. I'm needing more crayfish tattoos. What species should I get? 🤔🦞 #CrayWeek

@Cray_Bay99 Just wait until I find them

Recently took some folks from Fish and Wildlife to see the Caney Mountain Cave Crayfish (Orconectes stygocaneyi). It is considered the rarest crayfish species in North America as it is found only in one pool in one cave in the entire world. #CrayWeek
