The graceful splayfoot salamander (Chiropterotriton cracens), also known as the graceful flat-footed salamander, is a species of salamander in the family Plethodontidae. It is endemic to the state of Tamaulipas in northeastern Mexico. Its type locality is near Gómez Farías, Tamaulipas.[3]

Description

Chiropterotriton cracens is a small, slender salamander. Adults measure 24–31 mm (0.94–1.22 in) in snout–vent length. The tail is long, maximally 1.5 times the snout-vent length. Limbs are well developed; hind legs are slightly longer than forelegs. Dorsal colour is light brown, sides are slightly darker.[2]

Females collected in summer had more and smaller eggs than those collected in spring when eggs were quite large, 1–2.5 mm (0.039–0.098 in), but few in number (3-5 per side). Juveniles (12–14 mm (0.47–0.55 in) body length) have been collected in May and August.[2]

Habitat and conservation

Its natural habitat are cloud forests between 1000 and 2000 meters elevation, where it lives in bromeliads.[1]

Chiropterotriton cracens only known from the El Cielo Biosphere Reserve, a protected area. Despite this, Chiropterotriton cracens has declined. The reasons for this decline are unknown but could relate to climate change or disease (e.g. chytridiomycosis).[1]
