Saddleback Crayfish (Saddlebacked Crayfish)
The most obvious feature of this crayfish is the bold blackish band (saddle mark) across the hind margin of the carapace; note also the absence of dark blotches or specks. Another dark bar crosses the head just in front of the cervical groove (the groove separating head from thorax). The pincers are broad and powerful. Similar species within the range of this species are the golden crayfish (Orconectes luteus), which has a darker abdomen and red on many body parts, and the belted crayfish (O. harrisoni), in which the forwardmost saddle spans the cervical groove.
