majulus majalis和Cyprinodon variegatus有丰富的白色细胞（“guanophores”，与虹膜细胞相对），反应活跃，比黑素细胞慢。“背景”。当放在黑色的碗里时，这种白色的“色素”变得浓缩；在白色、浅蓝色或黄色的碗中，它变得分散，增加了皮肤的苍白。这些反应（在F. majalis中）不依赖于脑垂体。它们没有通过麦角化来检查，麦角化可以消除黑色素的扩散。大多数黑色素细胞与白色细胞结合在一起，而白色细胞并不是黑色素细胞的组成部分。
Fundulus majalis and Cyprinodon variegatus have abundant leucophores ("guanophores," contrasted with iridophores) that respond actively, slower than melanophores. to "backgrounds." When in a black bowl, this whitish "pigment" becomes concentrated; in a white, light blue or yellow bowl it becomes dispersed, augmenting skin pallor. These responses (in F. majalis) do not depend on the pituitary. They were not checked by ergotization which abolished melanin dispersal. The leucophores are not integral parts of the melanophores with which most are combined.
