Guinea Fowl Puffer (Arothron meleagris) aka Spotted Puffer comes in two distinct color phases which look like entirely different species. They come in a spotted phase where the puffer is dark with white spots and the gold phase pictured above.
The Guinea Fowl Puffer has a fused beak-like structure which it uses to crush prey. While "puffed up," its spines are held straight out from the body to discourage others from trying to eat it. Parts of the flesh are poisonous if digested.
They eat invertabrates and live in the Indo-Pacific area. They can grow to more than a foot in length.
