Its species range is very large and extends far beyond the tropics. Its body size is the largest of any erethizontid. Its diet includes tree bark to a greater extent than shown by any other erethizontid. Its tail lacks prehensile function and functions instead as a powerful quill-delivery system.<\/p>\n Recently, in collaboratiuon with Drs. Gaston Gine of the Univ. Estaduel de Santa Cruz, Brazil, and David Chapman of Lakehead University, Canada, I have become interested in the anatomy and natural history of another atypical erethizontid, the thin-spined porcupine, Chaetomys subspinosus<\/em>.\u00a0Chaetomys<\/em> has had a long evolutionary separation from other New World porcupines and belongs to its own sub-family, the Chaetomyinae. It is the only New World porcupine with quills that lack one-way barbs. Its range is restricted to the Atlantic Forest of southeastern Brazil, and because this forest has been 92% destroyed, Chaetomys<\/em> may be the most endangered of the New World porcupines.<\/p>\n 2023.
