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 centimetres (18 in).
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 colouration with faded yellow. It feeds mainly on algae, but will also feed on sponges, crustaceans and molluscs.
Carving on fruit pits is a traditional kind of art in China. Since the 18-19th centuries, carving on apricot and peach stones were preserved, recently carving on olive pits (canarium species) became widespread in Asia.
Seeds of Canarium reach a size of 50-60 mm in length and 30 mm in diameter, with a wall thickness of 10-15 mm, an average pit size of 30-35 mm.
The bone of the seeds is hard, has a sufficient density for fine carving. In texture, the material is identical to organic bone (bones, teeth and tusks of animals), but it is lighter than ordinary bone.
