Porcupines are large, slow-moving rodents with abrupt quills on their backs. They are found on every continent except Antarctica. Scientists grouping porcupines into two groups: Old World porcupines, which are establish in Africa, Europe and Asia; and New Earth porcupines, which are found in N, Fundamental, and South America. The North American porcupine is the but species found in the United States and Canada.

Precipitous quills

All porcupines take a few traits in common. The almost obvious trait is the long, sharp quills that cover their bodies. Some quills can get up to a human foot (xxx centimeters) long, like those on the Africa's crested porcupine, according to National Geographic (opens in new tab).

If that doesn't work, they may charge backwards into the predator. The quills are loosely fastened but cannot be thrown or projected, according to the Animate being Diversity Web. Some quills accept scales or barbs that make them very hard to remove. In one case a quill is lost, it isn't lost forever. They grow back over time. A North American porcupine tin can have 30,000 or more quills, according to National Geographic.

Size

The largest porcupine is the North African crested porcupine. Information technology grows upwardly to 36 inches (90 centimeters) long. The smallest is the Bahia hairy dwarf porcupine. It grows up to 15 inches (38 cm) long. Porcupines weigh 2.five to 77 lbs. (one.2 to 35 kilograms), depending on species, and their tails can grow up to 8 to 12 inches (twenty to 30 cm), co-ordinate to the San Diego Zoo.

The length of quills varies past type. New World porcupines take modest quills that are around 4 inches (10 cm) long, while Erstwhile World porcupines have quills that can abound up to 20 inches (51 cm) long, though there are some exceptions.

Habitat
