A new and gorgeous 'Bama crayfish
Procambarus spp. are burrowing crayfish that spend most of their lives in complex underground tunnels. They've thus taken on a bulldozer-like morphology - like supersized versions of reef pistol shrimps.
The newly described Procambarus holifieldi is most closely related to Procambarus (Girardiella) barbiger, another crayfish from the South (Mississippi).
