Abstract
Ongoing research shows that how hair varies-between species and even on the same animals-and how he developed a database of mammal hair that can be used by wild life forensic scientist to identify hair in cases of illegal trafficking of the world’s most endangered animals. Hair samples from some domestic and wild animals were evaluated in this study. The main hair structures (cuticle, cortex and medulla) were investigated. The guard hair diameter, colour, shaft, cuticle pattern, the medulla, the scale patterns and, root were examined using a light microscope. The current research on morphologic characteristics of animal hair can be performed to provide more information for wild life forensics and allowing for the identification of illegal transport of animals, poaching or wildlife crime, fraud in textile and fur industry, and dentification of their victims, etc. In the present study, different animal hairs collected from National Zoological Park, Pragati Maidan, New Delhi, India were microscopically examined. Wild life animal species like Baby sheep hair, baby goat hair, bear hair, buffalo hair, cattle hair, deer hair, Doberman dog hair, dog hair, emu hair, flamingo feather, goat hair, Labrador dog hair, sheep hair, tiger hair identification /characterization using microscopic hair characteristics is discussed here. As part of a research project, this paper provides data that allow rapid and low cost animal species identification based on the hair microscopic features because hair is strongly resistant from decomposition and this property makes hair a nearly ideal type of physical evidence.

Summary
Evidence of animal hair, is often discovered at crime scenes. Pet or other animal hairs can be found on the clothes of the victim or on other items of physical evidence collected at the crime scene. The identification and analysis of human and animal hairs from a crime scene can indicate physical contact between the victim and a suspect, or provide other investigative leads. Forensic hair analysis is a scientific method of analyzing trace evidence from a crime scene. It involves examining the hair shaft, including its medulla (inner core), cortex (intermediate layer) and cuticle (outer covering) through powerful microscopes. The first step of the examination involves verifying whether the hair in question is that of a human or an animal. If the hair is from an animal, the examiner can potentially identify the species from which it originated [2]
