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.

Another porcupine, facing the other way. The unporcupine is extinct. Oh wait, what about a HEDGEHOG?

Like other mammals, porcupines do in fact have lungs

we,ve had problems for years in upstate pa. with these critters. An older gentleman told us to try fox urine, we,ve sprayed it around our garage and cabin and has worked pretty well. not 100% but has cut our visits from them down cosiderably.

No
it is a herbivore and a carnivore

According to Bob Hirshon for AAAS www.scienceupdate.com Otolaryngologist Yehuda Finkelstein performed a study in nine types of animals, including sheep, baboons, and chimps and of all the animals studied he found that only a few baboons have underdeveloped uvulas. Dogs do not have uvulas, and so we can conclude that only the human has the uvula.

The fire ant will bite you, leaving a bad rash or sore which is very itchy. This is where they get the name 'Fire Ant'.

He meant that "bad men" care only about indulging their most basic instincts. "Good men" address the most basic instincts as necessary, so they can then go out and do something worthwhile with their lives.

Because some animals have more predators or they are more exposed to dieseses therefore they might die before they are adults

fishers, and occasionally hawks and some snakes

Porcupines attack because of fear - if they feel scared or threatened, they will attack or attempt to warn off their enemy.

A mammal is a warmblooded vertebrate animal of a class that is distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young, and (typically) the birth of live young.

This applies to porcupines, so they are mammals.

The vet removed the quill from the dog's nose. The quill pen was difficult to write with.

Porcipines and hedgehogs.

Porcupines have those sharp spines for a reason! It's a defense mechanism and protects them from predators! they were born that way. god made them that way

Scaled fish often obtain food by eating plants and animals that are smaller than themselves. Some fish have teeth or hard bony structures that can help to crush them into smaller pieces.

It is very difficult to tell a male and female porcupine apart externally. The females are slightly smaller and have mammary organs while males have a penis which you cannot see from a distance.

Yes they do. I saw three on Friday - immediately west of Oklahoma City, another 30 miles west and one near Woodward, OK.

Yes. A porcupine is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.

Porcupine comes to us originally from Latin (porcus 'pig' + spina 'thorn.') and fron thence to Late Middle English which took it from from Old French "porc espin" and the Provençal porc espi(n ). All essentially relaying the idea of Thorny Pig

Porcupines have approximately 30,000 sharp quills on their bodies, and although they might seem vicious, porcupines are actually timid creatures. Contrary to popular belief, these creatures don't go out of their way to quill people or pets. Those who are quilled by a porcupine are quilled because they came into direct contact with the animal, and the porcupine was only trying to protect itself. People cannot be impaled by a porcupine throwing quills. In short, they are dangerous if you somehow fall on a porcupine, but are not poisonous by any means.
