Dog-faced Puffer
Arothron nigropunctatusAlso known as Blackspotted Puffer, Black-spotted Pufferfish, Dog-faced Pufferfish
Dog-faced puffers charm divers with their remarkably canine-like facial features, expressive eyes, and slow, hovering swimming style. These reef residents rely on a powerful beak to crunch through tough corals, sponges, and hard-shelled invertebrates. When threatened, they inflate their bodies with water to deter predators, backed by a lethal concentration of tetrodotoxin in their internal organs.

Never attempt to handle, touch, or feed this fish; observe from a respectful distance while diving or snorkeling.- Keep your distance: Avoid crowding or cornering them, as stress can trigger their puffing defense.
- Do not touch: Their skin lacks scales and is highly sensitive, and they can bite if handled.
- Observe feeding: Watch them cruise just above the reef, using their fused teeth to crunch on hard corals.
