Red-Swamp Crawfish

Post by Marcepstein »

I came across this Red swap crawfish (Procambarus spp.) - bearing claws in protective display while it was crossing a landscape. It was early morning, no flash, handheld with a 1DM4, ef100mm macro lens at f4, 1/60, 1250iso. Best I could do at the time which was a while ago. Just an interesting image. It was a gravid female.

The first shot is something I have never seen, used to find the British crayfish, Austropotamobius pallipes quite regularly when surveying streams and small rivers in the Welsh Marches but never witnessed them moving across land. It's a lovely shot.

Thanks, Adrian. The crawfish was walking across a lawn scape on the Santee National Wildlife Refuge .. spellcheck mush have put in landscape and I didnt notice it. The refuge is contiguous with Lake Marion and as I understand, has the Red Swamp Crawfish (Procambarus clarkii), which is considered an invasive species, and the Louisiana White River Crawfish (Procambarus acutus) that is native. There maybe more in the lake that Im not aware of. There are lots of snakes, raccoons and opossums that roam the area, so I guess it was fortunate to make it that far.
