Clownfish have ultraviolet light vision: Study

A study by the University of Queensland and the University of Maryland reveals that the clownfish species Amphiprian acodinos can see ultraviolet (UV) light. Researcher Sarah Steve explains that these fish live near the water surface where UV light penetrates easily. Their eyes have photoreceptors for detecting UV and violet light, enabling them to identify each other by the UV-reflective white stripes. This ability aids in communication and helps them find food like zooplankton, which appear as dark dots due to UV absorption.
