Unlike all other porcupines the Thin-Spined Porcupine's tail is not usable for climbing trees.

Usually the porcupine is as slow moving as a sloth but when in danger it can quickly scurry away. If not they use their spines/quills to scare away predators. That is why the Thin-Spined Porcupine's main predator are humans.

The spines on it back are more bristle like than others. Hence having the name Bristle-Spined Rat.
