Allomycterus Chilomycterus Cyclichthys Diodon Dicotylichthys Lophodiodon Tragulichthys Porcupinefish are medium-to-large fish belonging to the family Diodontidae from the order Tetraodontiformes[2] which are also commonly called blowfish and, sometimes, balloonfish and globefish.

They are sometimes collectively called pufferfish,[3] not to be confused with the morphologically similar and closely related Tetraodontidae, which are more commonly given this name.

This increase in size (almost double vertically) reduces the range of potential predators to those with much larger mouths.

[5] Porcupinefish are eaten as food fish and are an exotic delicacy in Cebu, Philippines, where they are called tagotongan.

The porcupine fish (as Diodon antennatus) is mentioned in Charles Darwin's famous account of his trip around the world, The Voyage of the Beagle.
