Yellow boxfish – a yellow fantasy under the blue Ocean.

A yellow fantasy under the blue Ocean
The Yellow boxfish (Ostracion cubicus) is a genus of Ostracion. This yellow species also known as Blue-spotted Box-fish, Cubed Boxfish, Cubical Boxfish, Polka Dot Boxfish and Yellow Trunkfish. The Yellow Boxfish inhabits coral and rocky reefs, and it is found at depths of 1 m to 40 m.

It can be recognized by its box-shaped body, bright yellow colouration and black spots. Juveniles have black spots about the size of the pupil. As it ages, the brightness fades and very old specimens will have blue-grey coloration with the faded yellow, sometimes even changing to white spots with a black margin. It feeds mainly on algae, but will also feed on sponges, crustaceans and mollusks. It reaches a maximum length of 45 centimeters (18 in).
