星鼻鼹鼠（Condylura cristata）的喙具有奇特的行为和结构特化。九个位置和运动的光线与各种上下文进行了描述。叮咬集中在强电点（阴蒂和生殖孔）时，追求淹没蠕虫，如蚯蚓。在他们的第一次试验中，七只鼹鼠中有六只更喜欢模拟电场的电子束，而不是没有电场的相同排列。星星的运动、鼹鼠的行为和初步的实验都与星鼻鼹鼠使用电感觉来探测猎物的假设相一致;结论必须是暂时的，直到有可能从单个鼹鼠或从更大的个体样本中获得重复的反应。
The star-nosed mole, Condylura cristata, possesses curious behavioral and structural specializations of its proboscis. Nine positions and movements of the rays associated with various contexts are described. Bites were concentrated on strong electrical spots (clitellum and reproductive pores) when pursuing submerged worms, such as Lumbricus terrestris. On their first trials, six of seven moles preferred the simulated electrical field of an earthworm rather than an identical arrangement without an electrical field. Star movements, mole behavior, and preliminary experiments are consistent with the hypothesis that the star-nosed mole uses an electrical sense to detect prey; conclusions must remain tentative until it is possible to obtain repeated responses from individual moles or from a larger sample of individuals.
