Species often confused with {name}
Starry Puffer
Arothron stellatus
Key differences: Arothron stellatus typically has a darker body color (often dark brown to black) with numerous white or pale yellow spots, which are generally larger and more star-like than the blue spots of A. caeruleopunctatus. Juveniles of A. stellatus are often black with large white spots, while adults develop smaller spots and a lighter background.
White-spotted Puffer
Arothron hispidus
Key differences: Arothron hispidus has a dark body with numerous white spots, but crucially, it also possesses distinct white lines or bands around the pectoral fin base and often around the caudal peduncle, which are absent in A. caeruleopunctatus. The spots on A. hispidus are typically larger and more uniformly white, lacking the iridescent blue hue.
Black-spotted Puffer
Arothron nigropunctatus
Key differences: Arothron nigropunctatus is typically uniformly colored (yellow, grey, or black morphs exist) and lacks the distinct blue spots. It may have black blotches around the pectoral fins or mouth, but not the widespread blue spotting.
