Rothschild’s Porcupine (Coendou rothschildi)

…a species of New-World porcupine  that is native to Panama and western Ecuador. Like other members of the genus Coendou Rothschild’s porcupine has a prehensile tail, which aids them in their arboreal habitat. Rothschild’s porcupines are nocturnal and live off a diet of mostly fruits and leaves. During the day they can be seen sleeping in vine tangles at the tops of trees.

"The North American porcupine (Erethizon dorsatum), also known as the Canadian porcupine or common porcupine, is a large rodent in the New World porcupine family. The beaver is the only larger rodent in North America. The porcupine is a caviomorph rodent whose ancestors rafted across the Atlantic from Africa to Brazil over 30 million years ago, and then migrated to North America during the Great American Interchange after the Isthmus of Panama rose 3 million years ago. They range from Canada, Alaska, and into northern Mexico. They are commonly found in coniferous and mixed forested areas but have adapted to harsh environments such as shrublands, tundra and deserts. They make their dens in hollow trees or in rocky areas.”

Stump-tailed Porcupine (Echinoprocta rufescens)

…a rare species of New-World Porcupine that occurs in Colombia, although individuals have been sighted in neighboring countries like Ecuador. Like its common name suggests, this species is unusual in that it has a short tail, unlike other porcupines. Little is known about E.rufescens' biology, other than it inhabits montane/secondary forests and is thought to be nocturnal, solitary, and arboreal.
