Sun Bear
Smallest bear, longest tongue — orange chest blaze and honey-raiding rainforest stealth.
Vulnerable
Helarctos malayanus
Overview
Sun bears are the smallest bears, climbing Southeast Asian rainforests with sickle claws and an extraordinarily long tongue for honey and insects. A cream-to-orange chest patch varies like a fingerprint between individuals.
For Indonesia collectors, the sun bear is a rare Borneo–Sumatra forest prize — compact, arboreal, and marked with that signature sun bib.
