This creates a warning noise, meant to deter predators. They then wave their tails around in an attempt to hit the predator with their sharp quills. Hedgehog quills, also called spines, are much shorter than the average porcupine quill at around 2. Porcupine quills vary significantly in length between the various species, but they can grow up to 30 cm long on the crested porcupine in Africa. However, the quills are barbed and easily detachable, which can make for some seriously nasty injuries.
So, how did these two barely-related animals end up with such similar defense mechanisms and appearance? The answer is convergent evolution. This is a phenomenon where unrelated animals evolve similar traits due to them facing similar evolutionary pressures. It turns out that quills are an excellent defense, so both animals ended up evolving them entirely separately. Hoglets baby hedgehogs are born with swollen skin that covers their baby quills to protect their mothers. Gradually, these quills emerge and promptly begin to fall out.
These baby spines are then replaced with their adult spines, in a process that can be painful and leave them in a bad mood. Soon enough, though, the hedgehog has a full set of adult quills, and the ordeal is over. However, some hedgehogs go through additional, less severe stages of quilling over the following years.
They will happily lose and regrow quills throughout their lives. Despite their size and impressive weaponry, porcupines are mostly herbivorous. North American porcupines eat twigs , leaves , and green plants such as clover. They also occasionally eat bark and will regularly climb trees in search of sustenance. Surprisingly, dainty hedgehogs are the meat-eaters out of the pair. They are primarily insectivores, eating things like beetles , caterpillars , worms , slugs , and other invertebrates.
They do follow a rough cycle of 9 days on and 7 days off, but they are considered induced ovulators, and will ovulate, or go into heat, when in the presence of a male.
In male hedgehogs the penile sheath is located about halfway up the tummy and looks like a large belly-button. In females the sex organ is directly adjacent to the anus. Both sexes have a row of nipples along each side within the tummy fur. In babies, it can be difficult to tell sexes apart due to the small size.
So, do hedgehogs die easily? Hedgehogs can die easily, with death from poor diets and diseases being the major factors that affect the lifespan of hedgehogs.
Moreover, since hedgehogs hide their illnesses, many people cannot tell when these creatures are sick or almost dying until it is too late. Colour of spines i. On camera, dark medium or light. What should I feed a hedgehog?
Hedgehogs are lactose intolerant so milk can make them very ill and should never be offered. Instead, put out a dish of fresh water each night. Many people ask if the hedgehog animal ambassador at the Dickinson County Nature Center is related to a porcupine. However, hedgehogs and porcupines aren't actually related at all. There are 17 different species of hedgehogs, and their closest relations are actually shrews and moles.
There are more than two dozen species of porcupines in the world, and they are a part of the rodent family. Here are some other differences between these creatures that seem more alike than they really are:. Hedgehogs have short quills, sometimes called spines, that about 1 inch long. Hedgehogs do not lose their quills, except for quilling as a baby read about that here and a few here and there throughout their lives like humans lose hair.
Porcupines have longer quills than hedgehogs. Some species have inch quills while an African species has quills almost a foot long. Porcupine quills easily fall off. Perhaps the most noticed difference between hedgehogs and porcupines is how they use their quills to defend themselves. Hedgehogs will roll into a ball and erect their spines so that no part of their soft body is showing. That way, predators don't have anything to bite and are deterred by the spiky creatures.
Hedgehog rolled in a ball. A porcupine will arch its back and stick up its quills, waving its tail around to hit a predator so its quills will stick into the attacker. Short-beaked Echidnas are part of a group of mammals called monotremes. Females lay a single egg, which is incubated for about 11 days before it hatches. The baby , called a puggle, completes its development in the mother's pouch. Echidnas forage through rotting logs, stumps and the leaf litter in search of termites and other invertebrates.
Echidnas obtain most of their water needs from the animals they eat but they will also occasionally drink from pools or lick droplets of water from plants moistened by dew or rain. You can't tell if an echidna is male or female by simply looking at them as they have no gender-specific features and their reproductive organs are internal. All echidnas are born with spurs on their hind limbs, similar to what male platypuses have.
Most mammals give birth to live young. Platypuses , however, lay eggs. They are a species of primitive mammals called monotremes. Echidnas, or spiny anteaters, are the only other mammals that lay eggs. What is the difference between a porcupine and an echidna?
