Bothrocophias microphthalmus, the small-eyed toad-headed pit viper, is a venomous member of the family Viperidae (Wikipedia, general species account). It was described by Cope in 1875, and its type locality lies between Balsa Puerto and Moyobamba in Peru (Nogueira 2019).
It lives in forest, on the ground, at elevations roughly between 830 and 1800m (Oskyrko et al. 2024). Across its range it is known mostly from Amazonia, in Bolivia, Brazil, Colombia, Ecuador and Peru. In Brazil it is recorded from a single locality in western Amazonia at low elevation, and it has been observed in the field in forest (Nogueira 2019). It is venomous and gives birth to live young (ReptTraits, Oskyrko et al. 2024). Its maximum recorded total length is about 1.16m, and its maximum recorded body mass about 800g (ReptTraits, Oskyrko et al. 2024).
