The family includes many familiar species variously called pufferfishes, puffers, balloonfishes, blowfishes, blowers, blowies, bubblefishes, globefishes, swellfishes, toadfishes, toadies, botetes, toadle, honey toads, sugar toads, and sea squabs. They are morphologically similar to the closely related porcupinefish, which have large external spines.
