Your sentence is mostly correct, but it can be made clearer by adjusting a small detail. The phrase 'long spines' is better as 'long quills,' because porcupines have quills, which are a type of spine.

Corrected sentence:
Porcupines lift their long quills and rattle their tails to scare off enemies.

Explanation:
  • Quills vs. Spines: Porcupines have sharp quills, not just spines. Quills are the sharp, needle-like hairs on their backs that stand up when they feel threatened.
  • 'Lift their long quills': Means the porcupine raises its quills to look bigger and more frightening.
  • 'Rattle their tails': Porcupines can shake their tails, which causes the quills to make a rattling sound to scare enemies away.
