The spectacled bear is a relatively small species of bear native to South America. It has black fur with a distinctive beige-coloured marking across its face and upper chest. Males are 33% larger than females. Males can weigh 130 – 200 kilograms (286 – 440 lb), and females 35 – 60 kilograms (77 – 132 lb). They are found in several areas of northern and western South America, including western Venezuela, Colombia, Ecuador, Peru, western Bolivia, northwestern Argentina, and eastern Panama. Spectacled bears are the only surviving types of bear native to South America, and the only surviving member of the subfamily Tremarctinae. Their survival has depended mostly on their ability to climb even the highest trees of the Andes.
