Also 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.

Why interaction risk is high
Contains lethal tetrodotoxin if ingested and can deliver a painful bite with its powerful beak.
Why it is dangerous
Tissues contain tetrodotoxin, a potent neurotoxin that is lethal to humans and pets if consumed. They also possess a powerful, beak-like jaw capable of crushing shells and inflicting severe bites.
How to recognize a risky encounter
Recognizable by their rounded, dog-like snout, small black spots scattered across the body, and variable coloration ranging from grey to bright yellow.
What to do
Never attempt to handle, touch, or feed this fish; observe from a respectful distance while diving or snorkeling.
Responsible observation
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.
