Canthigaster aziz

Canthigaster aziz, known as Aziz's toby is a species of pufferfish in the family Tetraodontidae. It was described in 2020 by Keiichi Matsuura, Sergey V. Bogorodsky, Ahmad O. Mal, and Tilman J. Alpermann based on a single specimen collected from the northern Red Sea off of Saudi Arabia. It was trawled from a depth of 315 m (1033 ft), which is reportedly the second highest depth at which any fish of the genus Canthigaster has been collected. The only known specimen measures 2 cm (0.8 inches) SL. The species was named after the King Abdulaziz University. It is thought to have been collected over a hard substrate as the trawling gear used to collect it was severely damaged during operation.

Evolutionarily, C. aziz belongs to a unique and newly discovered lineage of Canthigaster, being phylogenetically distinct from all of its congeners.
