The porcupine and the echidna are two very different animals. * Echidnas are monotremes (egg-laying mammals) and porcupines are placental mammals, and belong to the rodent family. * Echidnas are found in Australia and Papua New Guinea but porcupines are found in North America and Africa. * Porcupine quills are used more as active defence, whereas the echidna spines do not do a great deal of damage but certainly deter would-be predators. * There are around two dozen species of porcupine, but only two species of echidna. * Porcupines vary in size, with some species ranging between 80 and 115cm in length (including the tail); echidnas average between 30 and 50cm in length. Porcupines may weigh 5-16kg, but echidnas weigh 2-5kg, with those in the south being heavier than northern echidnas. * Some varieties of porcupine have quills 30cm long, but echidnas' spines average 5cm long. * Porcupines have quite long tails; echidnas have short, stubby, hairless tails. * Porcupines eat seeds, fruit, leaves, grasses, dandelions, bark, buds, twigs and aquatic plants; echidnas live almost exclusively on termites and ants. * Porcupines can climb trees, but echidnas are strictly ground-dwelling animals.
They are complete different animals. They are VERY different animals. Look it up.

It has "parts" too!
There are several differences between a rat and a human skeletal system. Some of them include the fact that the human system is more complex with multiple parts unlike that of the rat, the other difference is in their sizes and so much more.
A rat terrier is the breed. Smooth is the coat - Flat/ short. You can also get Wire. Its the same dog...
