The ocellated lizard (Timon lepidus) exhibits an intricate skin color pattern made of monochromatic black and green skin scales, whose dynamics of color flipping are known to be well modeled by a stochastic cellular automaton. We show that the late-time probability distribution of the pattern corresponds to the canonical probability distribution of the antiferromagnetic Ising model and can be generated by dynamics different from the commonly-used Glauber. We comment on skin scale patterns generated by the Ising model on the triangular lattice in the low-temperature limit.
环斑蜥蜴（Timon lepidus）展示出一种复杂的皮肤颜色图案，由单色黑色和绿色的皮肤鳞片组成，其颜色翻转的动力学被已知很好地建模为随机细胞自动机。我们表明，该模式的后期时间概率分布对应于反铁磁伊辛模型的典型概率分布，并且可以通过与常用的格拉沃格不同的动力学来产生。我们评论了在低温极限下三角形晶格上伊辛模型生成的皮肤鳞片图案。
