头足类动物在改变视觉外观方面在自然界中是无与伦比的。这些软体动物在神经、荷尔蒙和肌肉的控制下进化出了一个复杂的真皮单位系统，产生了令人惊叹的各种身体模式。与电视屏幕上的像素平行，头足类色团可以被协调起来，产生戏剧性的、动态的和有节奏的显示，在这里统称为“动态模式”。这项研究考察了不同头足类类群动态模式的性质、背景和潜在功能。给出了21个物种的例子，其中包括11个以前未在科学文献中报道的物种。这些模式从简单的闪烁或闪烁模式，到涉及多个皮肤场的高度复杂的通过波模式。
Cephalopods are unrivaled in the natural world in their ability to alter their visual appearance. These mollusks have evolved a complex system of dermal units under neural, hormonal, and muscular control to produce an astonishing variety of body patterns. With parallels to the pixels on a television screen, cephalopod chromatophores can be coordinated to produce dramatic, dynamic, and rhythmic displays, defined collectively here as “dynamic patterns.” This study examines the nature, context, and potential functions of dynamic patterns across diverse cephalopod taxa. Examples are presented for 21 species, including 11 previously unreported in the scientific literature. These range from simple flashing or flickering patterns, to highly complex passing wave patterns involving multiple skin fields.
