Gyrinophilus palleucus necturoides, the Big Mouth Cave salamander, a lungless salamander, is a subspecies of the Tennessee cave salamander (Gyrinophilus palleucus). The Big Mouth Cave salamander lives in Big Mouth Cave and other caves in the Elk River drainage basin in Grundy County and Coffee County, Tennessee. The salamander was first described by Lazell and Brandon in 1962.{{Cite journal |last=Lazell |first=J. D. |last2=R. A.

Conservation status

While the TNC rates the Big Mouth Cave salamander as "critically imperiled", IUCN claims it is only "vulnerable".{{cite iucn |author=Geoffrey Hammerson|author2= Christopher Beachy |year=2004 |title=Gyrinophilus palleucus |page=e.T59281A11896704 |doi=10.2305/IUCN.UK.2004.RLTS.T59281A11896704.en |access-date=23 October 2023}} A study in 2007 by Brian T. Miller and Matthew L. Niemiller investigated the actual population size of the subspecies. They determined that the subspecies was actually abundant in Big Mouth Cave and other caves, contrary to popular concern.{{cite journal|last=Miller|first=Brian T.|author2=Matthew L.
