So biologically, there are plenty of species that display banding or patterns, warning patterns, to either be cryptical in the water or warn against being attacked, not the least of which is the pilot fish which spends a big slab of its life around the business end of a shark.
所以在生物学中，有很多的物种 身上有带状图案或警告图案， 用于在水中隐蔽自己 或是在遭遇袭击时发出警示， 其中之一的就是鲭类海鱼， 它们一生的大部分时间 都环绕在鲨鱼的周围。
