Description
Size: 12 cm TL

Color: Yellowish to reddish brown in color with the head, the body and the caudal fin having numerous small dark-edged pale greyish to bluish-white spots. About 8-10 bluish white lines radiate from the eyes on either side and there is a dark eye spot below the base of the dorsal fin

It is a robust and rather elongate with a long and produced snout. The nostrils are reduced to a single small opening on each side of the snout. The skin is tough and scaleless. The fins are spineless and include a single posterior dorsal fin with 8-10 rays, an anal fin with 8-10 rays, pectoral fins with 15-18 rays each and a slightly rounded caudal fin. Pelvic fins are absent.

The spotted sharpnosed puffer's viscera, gonads and skin are highly toxic and contain a toxin called tetrodontoxin. The species also produces a repellent skin secretion to repel potential enemies.
