# Masked Puffer (*Arothron diadematus*)

**Taxon:** Puffers (*Tetraodontidae*)  
**Conservation Status:** LC - Least Concern  


The masked puffer, known scientifically as Arothron diadematus, is a fascinating pufferfish species belonging to the Tetraodontidae family. This intriguing fish is native to the vibrant waters of the Red Sea, where it favors the coral-rich environments of fringing reefs. Living in the tropical marine climate, it can be found at depths of up to 20 meters (about 65 feet).

With a typical length of up to 30 centimeters (about 12 inches), the masked puffer is notable for its olive-green or grey body. One of its most distinctive features is the striking black mask that covers its eyes and pectoral fins, complemented by a black outline around its mouth. Although these fish are usually solitary, they do gather in groups during the mating season.

The masked puffer reproduces by laying eggs, a process known as oviparous reproduction. Some experts have debated its classification, suggesting that it might be a variant of the closely related Arothron nigropunctatus, which is found in the Indo-Pacific region.
