Telmatobufo bullocki (Bullock’s Mountains False Toad), a critically endangered frog residing in Chile.
Frominaturalist.org:
“It is extremely rare; extensive fieldwork in 1992–2002 turned up only a single adult. It occurs in fast-flowing streams in temperate Nothofagus forest. The tadpoles are free-swimming and feed on algae growing on submerged rocks. It is threatened by siltation of streams caused by clear-cutting. It occurs within the Nahuelbuta National Park.”
