Jumping Spiders

Harmochirus brachiatus

Harmochirus brachiatus, commonly known as the bristled or brush-legged jumping spider, is a species within the family Salticidae, which is renowned for its diversity, excellent vision, and remarkable jumping ability. Harmochirus brachiatus is a small jumping spider, notable for its distinctive front legs that are fringed with long bristles, which it uses in courtship displays and possibly to aid in hunting. This species, like other jumping spiders, has excellent vision, facilitated by large anterior median eyes, allowing it to detect movement and detail from a distance.
