How to tell it apart

Other Arothron puffers can also show a spotted body, but this species has a fixed field mark: the rings of white and dark grey that radiate around each eye, paired with a dark patch at the 'shoulder' above the pectoral fin.

Appearance

The body is light grey, greyish or yellowish, covered all over with white spots. Around the eyes and pectoral fins, these spots merge into concentric rings of white and dark grey. The underside is white, and there is a dark patch above the pectoral fin, at the 'shoulder'. The back, sides and tail fin are covered in white spots, and the belly carries white bars.

Habitat

It lives on outer reef slopes to at least 50 m, as well as on inner reef flats, in lagoons, estuaries and tidepools, in water from about 25 degrees C. Young fish are common in weedy patches within estuaries.

Did you know?

In 2018 a young white-spotted puffer turned up off Cyprus, the first confirmed record of this species in the Mediterranean Sea. Its eye-rings were still incomplete, a sign it was not yet fully grown.
