Cambarus cryptodytes, the Dougherty Plain cave crayfish or Apalachicola cave crayfish, is a small, freshwater crayfish endemic to Florida and Georgia in the United States. It is an underground species known only from waters associated with the Floridan aquifer.

Description

The Dougherty Plain cave crayfish grows to a length of about 53 millimetres (2.1 in) with antennae twice this length. It is a colourless species with unpigmented eyes, segmented cephalothorax and abdomen, a pair of slender chelae (claws) with a row or two of tubercles and long slender appendages. The rostrum is long and unadorned with tubercles or spines.[2][3]

Distribution

The Dougherty Plain cave crayfish is known from springs, wells and cave systems in the

USGS survey of the area, carried out between September 2014 and August 2015, revealed additional sites in Early, Miller, Mitchell, and Seminole counties.[4]

Biology

Little is known of the biology of this crayfish. It is probably an opportunistic

troglomorphic crayfish.[5]

Status

In 1996 this species was listed as "

Least concern" on the grounds that it has a broad range and is common within that range. It seems to be able to live in water with low oxygen levels and may be widespread in the aquifer away from locations that open to the surface.[1] Potential threats include removal of water from the aquifer for human use and contamination of the water by pesticides and excess nutrients from agricultural operations.[1]
