The Guineafowl Puffer is a relatively large puffer – growing to lengths of at least 20 inches (50 cm) – that lives on rocky and coral reefs in the Indian and Pacific oceans. Like all puffers, this species is known for its ability to “puff up” when threatened. The Guineafowl Puffer gets its common name from its resemblance to guineafowl birds. It is typically black and covered with small white spots. Some individuals, however, are bright gold with only a few spots. These two morphs can be observed swimming together on the same reefs.
