Turtles are reptiles of the order Testudines (the crown group of the superorder Chelonia), characterised by a special bony or cartilaginous shell developed from their ribs that acts as a shield. "Turtle" may either refer to the Testudines as a whole, or to particular Testudines which make up a form taxon that is not monophyletic.

Porcupinefish are closely related to pufferfishes but porcupinefish have heavier spines (hence the name porcupine) on their body. Also unlike the four-toothed pufferfishes, they have only a single plate of fused teeth in each of the upper and lower jaws, which explains the name "didontidae" or "two teeth."
