Abstract: up as a result of data obtained from specimens deposited in the Herpetological Collection of the Museu Paraense Emílio We present the first species amphibian list for municipality of Coari, state of Amazonas, Brazil.

Compared with other studies in eastern Amazonia, the region of Urucu presented a large number of anurans. (n= 68), further studies by, increasing the sampling effort, could prove this area to be richer in anurans than that observed so far. Nonetheless, it´s not possible to confirm this because the data collected were not standardized among studies. However, Introduction (2002), compiling data from Gascon and Pereira (1993) The Amazon has a great diversity of species of and Hoogmoed and Ávila-Pires (personal communication) amphibians, mainly due to the hot and humid climate, reported the presence of 53 species of anurans in the coupled with the availability of large bodies of water, region of Urucu, without presenting a list of species names. conditions that favor the occurrence of different forms Located south of the Amazon River, in the municipality and lifestyles (Duellman 1999; Galatti et al. 2007).
