Evaluation of injuries caused by anthropic action in snakes from Brazil.

Human behavior toward wild animals is defined by cultural influences and often is affected by lack of knowledge, mainly in situations of confrontation. The present study was conducted between 2008 and 2013, involving analysis of snakes that had suffered injuries belonging to the reptile collections of Centro Universitário de Lavras and Universidade Federal de Juiz de Fora. The injuries were classified according to location on the body. Among the 449 specimens analyzed, 245 specimens showed injury to some part of the body. The nonvenomous snakes were the most representative and had a higher rate of injury (66.3%) than the venomous ones (18.2%). The body region where the greatest percentage of injuries was recorded was the anterior (39.6%), followed by the middle (36.5%) and posterior (8.4%). We believe this fact may have resulted due the lack of knowledge on how to differentiate species. Studies of the relationship between schooling level and contact with environmental education activities demonstrate reduction of attacks on these animals. This fact indicates that the preservation of many species is related to awareness and education of the population.
