Have you ever seen a fish that looks angry? Of course, it's the yellow boxfish (Ostracion cubicus), and when stressed or angered, it produces toxins that protect the species from its predators. Juvenile yellow boxfish are bright yellow with large blue or black dots. However, when juvenile boxfish grow into adult boxfish, they will be very dusky, and the dots become negligible. Thus, the full-body color completely changes from bright yellow into greenish or brownish.

The yellow boxfish has some other names, such as yellow trunkfish (yellow-color, sheathing of octagonal plates with a stiff box-shaped), blue-spotted boxfish (bright yellow-colored with blue spots), white cubicus, Polka dot box-fish (the boxfish; polka dot in their body), cubed box-fish, or cube box-fish by considering their shape and color.

Inspired by the aerodynamically, self-stabilizing fins of the yellow boxfish, the German automotive company Mercedes-Benz publicly announced its bionic concept car for the first time in 2006.
