P. baileyi grows to around 12 centimetres (4.7 in) SL and can be identified by sparse, or dense, coverage of epidermal outgrowths or cirri on the head and body.[3] The cirri tend to be more profuse in the juvenile state, becoming reduced or non-existent at higher ages. The abdomen is usually golden or orange, with no other markings.[3] Like other pufferfish P. baileyi is scaleless.[3] it's known to be aggressive in aquarium.
