The collection of amphibians (Anura - frogs and toads) in liquid, is all organized in an iron cabinet, and standardized glasses with plastic screw caps. The collection currently has specimens mainly from Paraná, Santa Catarina and Mato Grosso do Sul, where the curator carried out his research. All specimens are individually numbered, and we currently have just over 500 specimens in the collection. However, our number exceeds one thousand specimens, because during the curator's expeditions, while still a student, a single notation was followed and many specimens were destined to other collections - specimens were deposited in the Museu de História Natural Capão da Imbuia, Museu Nacional do Rio de Janeiro, Museu de Ciências e Tecnologia da PUCRS, among others. We also have a collection of recordings of amphibian vocalizations, and soundscapes, which are also registered in SIBBR under the acronym CSUTF (Coleção Sonora da Universidade Tecnológica Federal do Paraná, Francisco Beltrão).
