— Four differently pigmented species of planarians were examined for UV‐B (Λ= 320 280 nm) tolerance and ability to delect and avoid UV‐B‐exposed areas. It was found that lighter‐pigmented species are more UV sensitive and that movement out of the UV‐B is directly related to UV sensitivity. Three species showed positioning preference corresponding to their pigmentation; the darker the species, the less avoidance of UV‐B. The white (unpigmented) species showed exceptional and very sensitive behavior.
