来自冰岛两个港口的鱼所产的成熟未受精卵主要呈红色和黄红色，但也有一小部分呈红紫色。两个着陆地点的鸡蛋颜色频率存在显着差异。在囊胚形成阶段，受精的红紫色卵在色调或彩度上没有显示出明显的变化。然而，随着原肠胚形成并覆盖蛋黄，尽管色调保持不变，但色度急剧下降。 当胚胎形成时，彩度持续降低，色调也开始发生变化，蛋黄中的红紫色色素消失，蛋黄的橙黄色油脂变得更加明显。在哈夫纳菲厄泽和胡萨维克收集的雄鱼中最常见的血浆颜色是红色，但观察到的色调覆盖了 60% 的可见光谱，范围从绿色到紫色。 Hafnarfijordur 和 Husavik 雄性之间在色调或明度方面没有显着差异，但在色度得分方面存在显着差异。雌性血浆色调几乎与雄性一样多变（跨越可见光谱的 45%），但集中在绿黄色区域。血浆、皮下胶状物与肤色相联系。来自海洋觅食地的鱼，无论年龄或性别，肤色都是绿色的；有人认为，这种颜色在吸虫栖息的近地表水域中具有神秘的功能。
Ripe unfertilized eggs derived from fish landed at two Icelandic ports were predominantly red and yellow-red, but a small proportion were red-purple. There was a significant difference between the frequencies of hues of eggs from the two landing places. During the phase of blastula formation, fertilized red-purple eggs showed no discernible change in either hue or chroma. However, as the gastrula formed and covered the yolk, the chroma declined dramatically, although the hue remained unaltered. When the embryo formed, the chroma continued to decrease and the hue also began to change as the red-purple pigment disappeared from the yolk and the orange-yellow oil of the yolk became more visible. The most common plasma colouration in male fish collected at Hafnarfijordur and Husavik was red, but the observed hues covered 60% of the visible spectrum, ranging from green to purple. No significant differences between Hafnarfijordur and Husavik males in terms of hue or value were discerned, but there was a significant difference in chroma score. Female plasma hues were almost as variable as the males (spanning 45% of the visible spectrum) but centred in the green-yellow zone. Plasma, subcutaneous jelly and skin colours linked. Fish from the oceanic feeding grounds were all green in skin colour, whatever their age or sex; it is suggested that this colouration has a cryptic function in the near surface waters inhabited by lumpsuckers.
