Southern Puffer
Sphoeroides nephelus
Key differences: S. nephelus typically has a more uniform brownish or grayish coloration, often with indistinct spots, and lacks the prominent dark lateral band and distinct leopard-like pattern of S. spengleri. The dark spot at the pectoral fin base is usually less pronounced or absent in S. nephelus.
Checkered Puffer

Key differences: S. testudineus has a distinct reticulated or 'checkered' pattern on its dorsal surface, often with a yellowish background, and typically grows larger than S. spengleri. It also lacks the prominent dark lateral band.
Smooth Puffer
Lagocephalus laevigatus
Key differences: Lagocephalus laevigatus is much larger, has a smoother body (fewer or no prickles), a more streamlined body shape, and a silvery-gray coloration without the distinct spotting or banding of S. spengleri. Its caudal fin is deeply forked, unlike the rounded caudal fin of Sphoeroides species.
