Captured at a moment of sheer attitude that's both terrifying and funny, this Japanese macaque (snow monkey) exists in the steaming waves of Jigokudani Monkey Park, Japan. The photographer caught what might be the most severe "don't mess with me" face observed in the monkey realm. The monkey's austere look, complete with wrinkled brow and what looks to be a disapproving scowl, points to him having been designated as his family group's unofficial security agent. His facial expression and posture brilliantly reflect a martial arts master ready to show off his abilities; the analogy to a black belt in Kung Fu is especially fitting. The dramatic impact is enhanced by the steam rising from the hot springs in the backdrop, therefore producing an environment reminiscent of an action film featuring this amazing simian warrior.
