Animals of Costa Rica

Mexican Hairy Dwarf Porcupine

Category: Mammals

They can weigh up to 2.5kg as an adult and have fur that ranges from black to a light brown, with yellow quills. They have a naked, prehensile tail which helps them move through the trees. They move more slowly than other rodents of the same size.

Taxonomy (Coendou mexicanus)
Spanish Name Puercoespin
Conservation Status Least concern
Distribution From southern Mexico through to Panama.
Behavior They are thought to be primarily arboreal and have only be recorded moving to the ground to move to a new area which was not accessible through the canopy. They are completely nocturnal and are difficult to see as they forage high up in the trees.
Diet They are frugivorous which means that they mostly eat fruits but have also been known to eat leaves, too, however very little has been studied in regards to their diet.
Reproduction Females reach sexual maturity at around 19months and remain reproductively active for around 11 – 12 years. The quills are soft at birth and they harden within 2 to 3 days. Little is known about reproduction and parental investment in this particular species, however in closely related species, the young become independent between 8 and 12 weeks after birth.
Threats Despite their protective quills, they have been been known to be a prey item for ocelots as well as various birds of prey. Although various species of snakes also eat them, there have been reports of snakes dying from quills puncturing the lining of the gut or other organs. Humans hunt porcupines for their meat, and the fat and skin is believed to have medicinal values among indigenous people.
At Alturas We do not commonly receive porcupines at Alturas. Petal in our sanctuary was found by someone’s dog on the beach; she still had her umbilical cord attached and need lots of care to be able to survive. You may also remember in a past newsletter the porcupine we received after it was attacked by a dog that was successfully released. Now, we have a new baby in our nursery who hopefully will be released back into the wild as soon as he is big enough.
