Researchers found a new species of porcupines that live in trees near the Sao Francisco River in Brazil. The Coendou speratus is unique in that it has a completely spikey appearance characterized by brownish-red tips that contrast with its black dorsal fur. The area near the Sao Francisco River is known as a "hotspot" for biodiversity in Brazil, and is the fourth most important area for diversity in the world. Scientists detailed their findings in the journal Zootaxa.
