Black-Spotted Pufferfish

Arothron nigropunctatus

The black-spotted pufferfish (Arothron nigropunctatus) is a medium-to-large pufferfish reaching up to 33 cm, found throughout the Indo-Pacific. Its body is round and robust, typically grey to yellowish-brown, covered in distinctive black spots that vary in size and density between individuals. Some specimens display a striking yellow or golden color morph. Like all pufferfish, it can inflate its body by swallowing water when threatened, becoming nearly spherical and difficult for predators to swallow. It possesses tetrodotoxin in its skin and organs, making it highly toxic if consumed. This species inhabits coral reefs and lagoons, often seen resting on coral heads or slowly swimming along reef edges. It feeds on algae, sponges, tunicates, and small invertebrates, using its fused beak-like teeth to crush hard-shelled prey. Known for its docile and inquisitive nature, it often allows divers to approach closely, making it a favorite subject for underwater photographers. Its expressive face and slow, deliberate swimming style give it a personality-rich appearance.
