Species of Thailand
Binomial name: Ostracion cubicus, Carolus Linnaeus, 1758
The yellow boxfish (Ostracion cubicus) is a species of boxfish. It can be found in reefs throughout the Pacific Ocean and Indian Ocean as well as the south eastern Atlantic Ocean. It reaches a maximum length of 45 cm.
As the name suggests, it is box-shaped. When juvenile, it is bright yellow in color. As it ages, the brightness fades and very old specimens will have blue-grey coloration with faded yellow. It feeds mainly on algae, but will also feed on sponges, crustaceans and mollusks.
The fish's diet consists of marine algae, worms, crustaceans, mollusks, and small fish.
When stressed or injured it releases poisonous proteins from its skin that may prove lethal to any fish in the surrounding waters. The bright yellow color and black spots are a form of warning coloration (Aposematism) to any potential predators.
They are solitary animals. Breeding occurs during the spring, in small groups that consist of 1 male and 2 - 4 females.
In 2006, Mercedes-Benz unveiled its Bionic concept car, which was inspired by the shape of the yellow boxfish. It was assumed that due to the extreme agility with which boxfish maneuver, that their shape was aerodynamic and self stabilizing. However, analysis by scientists suggests that boxfish agility is instead due to the combination of an aerodynamically unstable body and the manner in which the fish use their fins for movement.
