Abstract
<jats:p>Brazilian mastofauna exhibits high diversity, including a significant presence of primates of the genus Callithrix, a group in which reports of color variations, such as albinism, are rare. In this context, taxidermy stands out as an important tool for conservation, morphological study, and support for environmental education, especially through biological collections. The objective of this study was to present taxidermy as a tool applied to the study and conservation of wild animals, as well as to describe the preparation process of the first specimen of an albino marmoset of the genus Callithrix sp. recorded in the wild, intended for the scientific collection of the IBIMM Institute. The carcass of the albino marmoset was used to perform the taxidermy process. The procedure involved a ventral incision, removal of the integument, tissue removal, cleaning, tanning with borax, mounting on a wire frame, filling with hydrophobic cotton, suturing, insertion of artificial eyes, and mounting on a plant support, followed by drying and chemical preservation. The procedure allowed for the preservation of the specimen’s morphological characteristics, including phenotypic aspects of albinism, such as depigmentation and reddish eyes. The material was properly prepared, stabilized, and finished, resulting in a specimen with structural integrity and scientific value, in addition to the collection of biological samples for complementary analyses. Taxidermy proved effective in the conservation and preparation of rare specimens, contributing to scientific research, teaching, and environmental education. The specimen was incorporated into the IBIMM collection, reinforcing the importance of biological collections as fundamental tools for the understanding and preservation of biodiversity.</jats:p>
