Conservation Status

Last record 1988

IUCN RedList status: Critically Endangered

The Shelta Cave Crayfish is critically endangered, possibly extinct (Schuster et. al. 2010), being known from only 17 specimens as well as a further 97 individuals which were recorded and then released over a 7 year period (1968 to 1975; see Cooper, 1975). No specimens have been recorded in the last two decades (Buhay & Crandall, 2008), and it is likely to be extinct given its very limited range of occupation >1km2.

The reasons for its decline, and presumed extinction, are believed to be a decline in the availablity of nutrients (in the form of guano) in the cave, as the result of Gray bats (Myotis grisescens) abandoning it. However, competition with the other two troglobitic species of crayfish in Shelta Cave (Oconectes australis australis and Cambarus jonesi) may also be partly to blame.
