Bullock’s false toad is a rare and elusive species, usually found under logs in temperate beech woodland.
Extensive fieldwork by several herpetologists within the range of this species between 1992 and 2002 has turned up only a single adult (in 2002). A second individual was recently seen in early 2011. The stomach contents of the first individual described by scientists were examined and found to comprise the remains of cockroaches, other insects and spiders, as well as a considerable mass of plant material. The major threat to the species is clear cutting and afforestation (converting land not previously forested) with pine plantations, which causes siltation of streams (which, in turn, makes it harder for the larvae to feed). Bullock’s false toad occurs in the Parque Nacional Nahuelbuta, although there are no specific conservation measures ongoing for this species
- Order: Anura
- Family: Calyptocephalellidae
- Population: Extremely rare
- Trend: unknown
- Size: 60-80mm
This species is endemic to Chile, found only in a few locations in the Nahuelbuta coastal range in the Arauco Province. It has an altitudinal range of 800-1,200 metres above sea level.
Habitat and Ecology
The Bullock’s false toad lives near fast-flowing streams that flow through temperate southern beech forest. Adults are found hiding under logs and they are known to breed in fast-flowing streams. The tadpoles are free swimming and feed by scraping algae from submerged rocks. The adults eat insects and also plant material, suggesting the frog has terrestrial feeding habits.
