在社会动物群体中实验性地整合仿生机器人已经成为理解社会行为基础和揭示动物交流基本决定因素的宝贵工具。在这项研究中，我们测量了生育雌性蓝鳍金枪鱼（Lucania goodei）的机器人复制品的纵横比，身体大小，运动模式和颜色形态的灵感来自成年男性？鱼复制品的运动是通过一个机器人平台来控制的，该平台模拟了在鳉鱼雄性中观察到的典型求偶行为。女性的位置偏好测量三种不同的颜色形态（红色，黄色和蓝色）。虽然雌性之间的偏好差异很大，但雌性往往会花更多的时间在黄色机器人复制品附近。这种偏好可能是因为黄色机器人复制品非常明亮，特别是与红色和蓝色复制品相比，在较长的波长（550-700 nm）下。这些发现与以前在食蚊鱼和斑马鱼中观察到的人工增强黄色色素的鱼类偏好一致。
The experimental integration of bioinspired robots in groups of social animals has become a valuable tool to understand the basis of social behavior and uncover the fundamental determinants of animal communication. In this study, we measured the preference of fertile female bluefin killifish (Lucania goodei) for robotic replicas whose aspect ratio, body size, motion pattern, and color morph were inspired by adult male killifish. The motion of the fish replica was controlled via a robotic platform, which simulated the typical courtship behavior observed in killifish males. The positional preferences of females were measured for three different color morphs (red, yellow, and blue). While variation in preference was high among females, females tend to spend more time in the vicinity of the yellow painted robot replicas. This preference may have emerged because the yellow robot replicas were very bright, particularly in the longer wavelengths (550-700 nm) compared to the red and blue replicas. These findings are in agreement with previous observations in mosquitofish and zebrafish on fish preference for artificially enhanced yellow pigmentation.
