[5] The Nashville crayfish has an orange and black coloration, four pairs of legs, and two elongate pinchers with red tips.

[7] Due to the lack of research on this particular species, the rest of the life history section are assumptions based on other crayfish.

[8] In general, crayfish eat algae, insects, worms, snails, fish eggs, leaves, and mussels.

Female Nashville crayfish can be found under large slab rocks while carrying eggs and young.

[11] The Nashville crayfish population faces a number of threats, including poor water quality due to local development, habitat degradation, and a restricted range.

While it was thought that the Nashville crayfish was only found in Mill Creek and seven of its tributaries, a disconnected second population was discovered in the Lower Tennessee River at the Pickwick Tailwater.

The USFWS reported that the species remained high in population numbers over the past 20 years in the Mill Creek area.

Despite recent metropolitan growth in the Nashville area, including commercial and residential developments, the species has remained stable or has increased in population numbers.

Like the 5-year review stated, the Nashville Metropolitan area is experiencing population, residential, and commercial growth.

Additionally, the area has been flooded with stormwater, sediment inputs, and spills of hazardous substances and raw sewage, yet the species’ population numbers have remained relatively stable or have increased.

The assessment suggests targeting an increase in water quality, however in most scenarios the populations of Nashville crayfish are predicted to survive in the next 40 years.

The 1989 Recovery Plan reports that the species is threatened by a variety of events resulting from urban development, including the possibility of chemical spill.
