Chemical immobilisation of eight juvenile spider monkeys in captivity (Ateles chamek) was carried out in the Taricaya Reserve located in the Amazon region of Peru for the purpose of health evaluation, sampling and morphometry. During this procedure the animals were thoroughly examined and samples of several types were taken per individual for further analysis. The analyses resulted in variations depending on the characteristics of each individual, however they yield data to establish basal parameters in the species. Rehabilitation projects allow a large number of evaluations to be performed on individuals, representing a pathway for research on threatened species. The present study aims to establish the evaluation of hematological, biochemical and morphometric and basal parameters of eight individuals of different sex but belonging to the infantile stage, the data then represent the evaluation even for a specific age and weight. It is important to collect the most data by having the opportunity to conduct research with threatened species.
