Apa Beza porcupine dengan Echidna dan Hedgeho

porcupine


Porcupines are rodents with a coat of sharp spines, or quills, that defend or camouflages them from predators. They are indigenous to the Americas, southern Asia, and Africa. Porcupines are the third largest of the rodents, behind the capybara and the beaver. Most porcupines are about 25–36 in (63–91 cm) long, with an 8–10 in (20–25 cm) long tail. Weighing between 12–35 lb (5.4–16 kg), they are rounded, large and slow. Porcupines come in various shades of brown, grey, and the unusual white. Porcupines' spiny protection resembles that of the unrelatederinaceomorph hedgehogs and monotreme echidnas.











Hedgehog Same Species With  Erinaceidae
A hedgehog is any of the spiny mammals of the subfamily Erinaceinae and the order Erinaceomorpha. There are 17 species of hedgehog in five genera, found through parts of EuropeAsiaAfrica, and New Zealand. There are no hedgehogs native to Australia, and no living species native to North America; those in New Zealand are introduced. Hedgehogs have changed little over the last 15 million years.[2] Like many of the first mammals they have adapted to a nocturnal, insectivorous way of life. The name 'hedgehog' came into use around the year 1450, derived from the Middle English 'heyghoge', from 'heyg', 'hegge' = hedge, because it frequents hedgerows, and 'hoge', 'hogge' = hog, from its piglike snout.[3] Other names include 'urchin', 'hedgepig' and 'furze-pig' .


Erinaceidae is the only living family in the order Erinaceomorpha, which has recently been subsumed with Soricomorpha into the orderEulipotyphla. Eulipotyphla has been shown to be monophyletic;[2] Soricomorpha is paraphyletic because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs.[3]

Echidnas  also known as spiny anteaters,[2] belong to the family Tachyglossidae in the monotreme order of egg-layingmammals. There are four extant species, which, together with the platypus, are the only surviving members of that order and are the only extant mammals that lay eggs.[3] Although their diet consists largely of ants and termites, they are only distantly related to the true anteaters of theAmericas. They live in New Guinea and Australia. The echidnas are named after a monster in ancient Greek mythology.


Monotremes (from the Greek μονός monos "single" + τρῆμα trema "hole", referring to the cloaca) are mammals that lay eggs (Prototheria) instead of giving birth to live young like marsupials (Metatheria) and placental mammals (Eutheria). The only surviving examples of monotremes are all indigenous to Australia and New Guinea, although there is evidence that they were once more widespread. Among living mammals they include the platypus and the echidnas (or spiny anteaters); there is debate regarding monotreme taxonomy
