加入发光脊椎动物行列的是太平洋多刺圆吸盘鱼，Eumicrotremus orbis，一种广泛分布在北太平洋的潮下带物种。除了它们迷人的外表，太平洋多刺圆吸盘以其腹部吸盘而闻名，该吸盘用于在不断变化的水流和潮汐中粘附在基材上。在这里，我们表明，红色lumpsuckers，这通常是男性和深红色的广谱光下，荧光明亮的红色下紫外线（UV）光和蓝光（360-460 nm），而绿色颜色变形（通常是女性）没有。在所有的颜色变形，吸盘发光绿黄色。雄性的红光与它们筑巢区域的硬壳藻类的红光相匹配，而吸盘可能是一个信号系统。在红圆斑吸盘鱼中观察到的绿色和红色荧光是最罕见的荧光模式，仅见于17个海洋鱼类科。太平洋多刺吸光鱼在广谱光下有神秘的颜色;我们观察到的荧光表明，在红光不存在或罕见的环境中，它们可能是一种潜在的交流和伪装途径。
Joining the ranks of vertebrates that glow is the Pacific Spiny Lumpsucker, Eumicrotremus orbis, a subtidal species widely distributed across the North Pacific Ocean. Aside from their charismatic appearance, the Pacific Spiny Lumpsucker is known for its ventral suction disc that is used to stick to substrates amid changing currents and tides. Here we show that red lumpsuckers, which are usually male and a deep red color under broad-spectrum light, fluoresce bright red under ultraviolet (UV) light and blue light (360–460 nm), while green color morphs (usually female) do not. In all color morphs, the suctorial disc glows green-yellow. The red glow of the males matches the red glow of encrusting algae in their nesting areas, while the suctorial disc may be a signaling system. The green and red fluorescence observed in red lumpsuckers is the rarest fluorescent pattern and is only seen in 17 families of marine fishes. Pacific Spiny Lumpsuckers are cryptically colored under broad-spectrum light; our observed fluorescence suggests a potential avenue of communication and camouflage in an environment where red light is absent or rare.
