Porcupinefish
Diodontidae
Key differences: Porcupinefish (Diodontidae) have large, rigid spines that are always erect, even when not inflated, and they possess two fused teeth (a single dental plate) in each jaw, unlike the four fused teeth of pufferfish. When inflated, porcupinefish spines stand out prominently.
Boxfish
Ostraciidae
Key differences: Boxfish (Ostraciidae) have a rigid, bony carapace covering their bodies, giving them a box-like or triangular shape. They cannot inflate their bodies and their locomotion is also distinct, often appearing to 'hover' with small fin movements.
Triggerfish
Balistidae
Key differences: Triggerfish (Balistidae) have a distinct 'trigger' mechanism with their dorsal fins, a more compressed body shape, and a different dental structure. While some can be aggressive, they do not inflate their bodies.
