Torquigener albomaculosus, or the white-spotted pufferfish, is the twentieth discovered[1] species of the genus Torquigener. The species was discovered in the ocean waters around the Ryukyu Islands in Japan off the south coast of Amami Oshima Island.[1] Observed depths of the species range between 10 to 27 m (33–89 ft).[1] The fish's head and body are colored brown with white spots at the back.[1] Its abdomen is silvery-white with white spots.[1]

The males are known for creating circular-shaped nests in the sand, measuring 2 m (6.6 ft) in diameter.[2] Such nest designs were noticed since 1995, but their creation remained a mystery until the species' discovery.[1] The nests are created to attract mates through the nest's impressive design and ability to gather fine sand particles, both of which influence a female's mate choice.[1][3] Males never reuse a nest.[3] As of 2014, the white-spotted pufferfish is thought to be the only species of pufferfish that create the shapes.[1]

In 2015, the International Institute for Species Exploration names it as one of the "Top 10 New Species" for new species discovered in 2014.[4][5]

Habits The white-spotted pufferfish have been known to create interesting sand patterns on the ocean floor to attract a mate. [1]
