Description

Palaemonetes cummingi is typically 30 mm (1.2 in) long, and almost colorless. It has a long, serrated rostrum, and no eye pigment.[2]

Distribution and ecology

Palaemonetes cummingi is endemic to a single flooded solutional cave in Alachua County, Florida.[2] The closely related species P. paludosus, is larger (up to 48 mm or 1.9 in) and has second pereiopods noticeably longer than the first.[2]

Conservation

Palaemonetes cummingi is the only cave shrimp to live in Florida. It has only ever been found at a single site, and has not been seen there since 1973.[2] It is listed as a critically endangered species on the IUCN Red List,[3] a threatened species under the Endangered Species Act,[4] and critically imperilled by NatureServe.[5] Other caves may exist in the area with undiscovered populations, but urban development around Gainesville, Florida, and the introduction to the caves of the redeye chub, Notropis harperi, both threaten its survival, and the species may already be extinct.[2]

gollark: Or, as <@332271551481118732> sort of suggested, blast chunks off it for mining.
gollark: I guess with a lot of heatproofing you could use geothermal power.
gollark: Well, 2.2 earth masses and high temperature... not good for manufacturing.
gollark: Use-impaired.
