Aracanidae

The Aracanidae are a family of bony fishes related to the boxfishes. They are somewhat more primitive than the true boxfishes, but have a similar protective covering of thickened scale plates. They are found in the Indian Ocean and the west Pacific. Unlike the true boxfishes, they also inhabit deep waters, of over 200 m in depth.

Fossil species
The family is represented in the fossil record by the extinct genus Proaracana with the single species P. dubia known from the Middle Eocene of Italy.
