The Correlation of Femur Length with The Body Length of Proboscis Monkey

Abstract

The proboscis monkey is an endemic primate of Kalimantan Island, Indonesia. According to the International Union for Conservation of Nature (IUCN), proboscis monkey was classified as endangered species. Anatomical data of proboscis monkey has not been available yet. As endemic and endangered primate, morphology and morphometric data of proboscis monkey are important for forensic reference. The purpose of this study was to investigate the correlation between femur and body length of the proboscis monkey. The anatomical analysis used three proboscis monkey from the rehabilitation center, Sahabat Bekantan Indonesia (SBI), Banjarmasin, South Kalimantan. The femur and body length were measured by digital caliper in millimeter (mm). The result showed that there was a strong correlation between femur and body length of the proboscis monkey. The body length of proboscis monkey might be determined by femur length with linear regression y = 0.2682x + 347.85. In conclusion, there was a positive correlation between femur and body length of proboscis monkey in South Kalimantan.
