The immaculate puffer is a pufferfish and has a rounded body with a short tail.

They are grey or light brown, though they have the ability to change this to a mottled grey-green coloration presumably used for camouflage.

[citation needed] They are usually found on sandy bottoms close to reefs and in lagoons to a depth of 30 meters.

[2] Immaculate puffers are often found hunting in patches of isolated rubble and in fields of sea grasses.

[2] The immaculate puffer is primarily carnivorous but has been reported feeding on sea grasses and mangroves as well.
