Normally, only one infant is born at a time. The infants are covered with short spines that are flexible at birth and harden soon afterwards. Young weigh 415 grams at birth and can climb almost immediately. Adult size is reached in less than a year. Sexual maturity for females is accomplished in 19 months.
Females mate right after the young is born.
These porcupines are nocturnal. During the day, they rest in trees at the height of 6 to 10 meters. When the porcupines get excited, they stamp their hind feet. If caught they roll into a ball. The tail is used to curl around trees while climbing.
