Whitespotted Puffer Identification Guide

Key identification features

• Grayish-brown to olive body covered in small white spots, finer and denser than in many related puffers
• Distinct dark ring encircling the eye and a dark stripe along the base of the pectoral fin
• Pale yellowish belly finely speckled with small black dots, contrasting with the spotted back
• Rounded body that inflates when threatened, with a small terminal mouth and fused beak-like teeth
• Fins are plain and translucent to pale yellow, without heavy spotting
• Typically grows to about 20 inches (50 cm)

Common look-alikes

• Star puffer (Arothron stellatus): grows much larger with spotting extending densely onto the fins and no dark eye ring or pectoral-base stripe.
• Guineafowl puffer (Arothron meleagris): dark morph shows larger, sparser white spots on a near-black body rather than fine even speckling.
• Stars and stripes puffer: shows striping toward the tail in addition to spotting, which the whitespotted puffer lacks.

Where you'll see one

Whitespotted puffers are common across the tropical Indo-Pacific, found over reef flats, sandy lagoons, seagrass beds, and occasionally in brackish estuary mouths, often resting near shelter during the day.
