What is a tree porcupine's length?

Tree porcupines, also known as the Brazilian porcupine or Coendou, typically range in length from about 24 to 30 inches (60 to 76 cm), not including their tails. Their tails can add an additional 12 to 16 inches (30 to 40 cm) to their overall size. These nocturnal rodents are notable for their spiny quills and arboreal lifestyle.
