It is a distinct but closely related species from Procambarus acutus, which is also known as white river crayfish and has a wider range.

[11] Their claws tend to become more cylindrical and elongated with age, appearing a lot finer or skinnier than other species in Procambarus.

They are a gonochoristic species, meaning there are two set sexes within a population, and the males typically have two different morphotypes, one being exclusively for mating.

[13] Females are recorded to lay their eggs in the mid- to late-fall period, typically producing an average of 130 babies per brood.

The eggs that are produced are individually larger but as an entire brood smaller than the closely related Procambarus clarkii, more commonly known as the Red Swamp Crawfish.
