Robust Boxfish: Male

Strophiurichthys robustus. 

The robust boxfish is a species of marine fish that belongs to the family Aracanidae. It is also known as the armored boxfish or the pinecone fish due to its unique appearance.

The robust boxfish is found in the tropical waters of the Indo-Pacific region, particularly around coral reefs. It has a distinctive body shape, which is box-like and covered in bony plates that provide protection from predators. The fish grows to a length of up to 15 centimeters (6 inches) and has a bright yellow color with black spots.

The robust boxfish is a nocturnal fish, which means it is more active during the night. It feeds mainly on small crustaceans and other invertebrates, which it finds by sifting through the sand or coral rubble on the sea floor.

The robust boxfish is not commonly kept in aquariums due to its specialized feeding habits and its tendency to release a toxin when stressed. In the wild, the fish is not considered to be of significant commercial importance, but it is sometimes caught for the aquarium trade.

Overall, the robust boxfish is an interesting and unique species that has adapted to its environment in a fascinating way. Its distinctive appearance and behavior make it a popular subject for underwater photography and observation.
