Hair Analysis of Mammals of Brazilian Wildlife for Forensic Purposes

Wildlife trafficking is classified as the fourth largest illegal commerce in the
world. Taxonomic identification of wildlife is an ordinary process for forensics
experts. The aim of this study was to analyze animal’s hair from Brazilian’s
wildlife through microscopic and compare morphology of bristle among
species analyzed. Hair samples of nine species were analyzed. Glass slides were
analyzed through optical microscopy and following measurements were obtained:
total length, medulla diameter, overall diameter and overall ratio diameter
of the medulla’s diameter. The images obtained at identification of
animals through the morphology of hair and the statistics analysis corroborates
in favor for the validation of the technique.
