A single albino specimen of the grass puffer, Takifugu niphobles (Tetraodontidae), was collected from the Suonada Sea, western Seto Inland Sea, Japan in November 2011. This specimen was an adult male of 164.6 mm TL and 133.9 mm SL. Its body was pale yellow, but the eyes were black. The condition factor and the gonadosomatic index were 106.6% and 0.75%, respectively. Histologically the testis was identified at the post-spawn stage. The specimen represents the first record of an albino in the world not only for T. niphobles but also for the family Tetraodontidae.
