50 interesting and amazing facts about hedgehogs

We’ll tell you amazing hedgehogs facts.

With the word “hedgehog” many of us immediately present a picture from a children’s book, on which a cheerful hedgehog family drags into the mink stuffed on the needles of mushrooms.

In fact, hedgehogs are cunning and clever predators who willingly eat not only mushrooms and berries, but in general everything that will be able to find. Or whoever they can catch.

Amazing facts about hedgehogs

  1. Hedgehogs are the most ancient mammals. These insectivorous animals have been inhabiting a variety of habitats in almost all climatic zones. The only areas where they do not live are permafrost and swampy areas.
  2. In ancient Rome, hedgehog skins were used as combs for combing out sheep’s wool. It’s interesting, that the courts of Ancient Rome were literally awash with cases of counterfeit hedgehog skins – so popular was this product.
  3. Hedgehogs make all kinds of noises. They snort, sneeze, grunt, grunt, snore, and clench their teeth.
  4. Hedgehogs have poor eyesight, but their sense of smell and hearing compensate for this deficiency.
  5. Hedgehogs are wonderfully tame and get along well with other pets – dogs and cats. But few people can keep hedgehogs at home because of their loud stomping at night.
  6. There are about 17 species of hedgehogs in the world.
  7. The most widespread, well-studied, and popular is our common, or European, hedgehog. However, it is so inaccurately called because it lives in the wide expanses of Eurasia all the way to the Pacific Ocean.
  8. A hedgehog’s pregnancy lasts 7 weeks.
  9. Communication between these animals is by whistling.
  10. It is very common to see hedgehogs killed under the wheels on country highways. Some people believe that these animals throw themselves under the wheels from the heat. In fact, hedgehogs tend to cross highways for a reason. The highways divide the animals’ habitat into fragments of a small area. To save the hedgehogs, ecologists suggest digging tunnels under the highways.facts about hedgehogs
  11. The closest relative of the common hedgehog is the long-eared hedgehog, which lives in the southern steppes, semi-deserts, and deserts. He differs very little from the common hedgehog: his ears are bigger, he is 2-3 times smaller, and his prickly shell is not so low on the belly.
  12. In pictures in children’s books hedgehogs are often represented as hoarders, carrying mushrooms and apples on their prickles. In fact, this is not true. Of plant food, they sometimes eat berries and fruit, but they never carry them on themselves; they are physically unable to curl up enough to do so. The “father” of the myth that animals carry supplies on their backs is the ancient Roman historian Pliny the Elder. Where he got it from is unknown. In winter they hibernate, but they do not need to make reserves – hedgehogs store nutrients in the form of fat.
  13. Common, i.e. European, hedgehogs are good swimmers. But sometimes they die in water because they can’t get out of a pool with steep banks.
  14. Unlike mongooses, which are totally immune to snake venom, hedgehogs, although they sometimes hunt snakes, are only partially resistant to venom. The protein protects hedgehogs from snake venom. However, if a snake bites a hedgehog several times, the battle may not end in his favor. 
  15. The hedgehog needs to gain enough fat reserves over the summer. If the hedgehog weighs less than 500 grams in October, it may die during hibernation. In early spring, hedgehogs sometimes wake up early. This is very dangerous for the animal, since the subsequent cold snap may kill it.
  16. amazing facts about hedgehogsHedgehogs are our helpers in dachas and vegetable gardens. They destroy insect pests and rodents. To lure a hedgehog into the garden, leave him something to eat in the evening outside (a piece of chicken, fish, dog or cat food, etc.). The animal will surely like the food and will visit you more than once, destroying slugs, caterpillars, May bugs, etc.
  17. While the hedgehog is hibernating its body temperature drops to 2 degrees Celsius (under normal conditions it is 34 degrees). Breathing in hibernating hedgehogs is seriously slowed down: maximum 8 breaths-exhales per minute, though usually, they breathe with a frequency of 40-50 times. An awakened hedgehog is a walking embodiment of hunger, so the animal spends several days after awakening exclusively in search of food.
  18. Most species of hedgehogs have a tail. However, it is very short – only 3 cm, so it is not visible from under the needles.
  19. The average hedgehog has about 10,000 needles. They are renewed once every three years. Hedgehog needles take a long time to grow, about a year. Luckily for the hedgehog, the renewal is gradual.
  20. Eared hedgehogs differ from their brethren in that they are extremely reluctant to curl up in a ball in case of danger. This species of hedgehog runs very fast, and it is not easy for terrestrial predators to catch up with it. If the eared hedgehog is overtaken by an enemy, the animal jumps up and tries to prick his adversary in sensitive places.
  21. The hedgehog is inquisitive, active, and energetic, and navigates a complex and dangerous world with a keen sense of smell and fine hearing, which are more sensitive than those of even a dog.
  22. African urchins cannot swim. Accidentally falling into the water, they inevitably drown.
  23. Even if pet hedgehogs are given enough food by their owners and left overnight, they still try to find something to eat under the sofa, in cupboards, and so on. Hunting instinct and biological rhythms cause hedgehogs to wake up at night and go hunting even without being hungry. Because of their peculiar gait and long claws, hedgehogs walk around the house accompanied by stomping.
  24. If a hedgehog is curled up in a ball, it will remain unharmed even if it falls from a height of several meters.
  25. Hedgehogs hibernate for 128 days.
  26. The fox cannot handle a prickly animal on land, but it can roll it towards the water, where it has to spread its prickles. This is where the fox grabs him.
  27. Hedgehogs do not hunt mice – this is a myth. They might be happy to eat a mouse, but they can’t catch it.
  28. Roast hedgehog is a traditional dish of the Roma. By the way, hedgehog goulash is mentioned in an episode of Guy Ricci’s “Sherlock Holmes: A Game of Shadows” when the main characters visit a gypsy tabor.
  29. With the help of radio beacons, scientists have found that animals overnight cover a distance of more than a kilometer, and the average habitat of one hedgehog can exceed 20 hectares. 
  30. Hedgehog needles are modified hair. They consist of keratin, inside the needles are hollow and reinforced with transverse septa. Because of this structure, they are very strong.
  31. In the steppes of Transbaikalia and Mongolia, the Daurian hedgehog is also the brother of the common hedgehog.
  32. Hedgehogs suffer from tick bites more than any other animal. When the hedgehog runs through the grass, it feels as if combing it, combing out parasites that will readily settle on the poor animal. The hedgehogs can’t get rid of mites because they don’t have needles of their own, so they use a clever trick: they put cigarette butts on themselves to etch the parasites with tobacco.
  33. Hedgehogs seem to be clumsy, but they are not. They can run very fast – up to three meters per second.
  34. In Serbian folk medicine, hedgehog urine is used as a cure for alcoholism.
  35. Large hedgehogs live from 4 to 7 years, and small hedgehogs live from 2 to 4 years.
  36. Hedgehogs are born completely blind and without needles.
  37. To get rid of slugs, gardeners use beer traps – they place plates of beer on the ground and then collect the pests. Hedgehogs don’t mind indulging in beer either – they like the taste of the foamy drink. Like other fans of beer, they may even fall asleep next to the plate or right in it! If the little beastie has drunk too much beer, it gets alcohol poisoning with all the accompanying symptoms.
  38. The eyes of newborn hedgehogs do not open until the 16th day.
  39. Constant crossing of hedgehogs between relatives leads to degeneration of the population, as genetic anomalies accumulate. Attempts of hedgehogs to find “brides” on the side lead to the fact that they crawl out on highways. This often ends sadly.
  40. Unlike their close relatives – moles, hedgehogs do not like to dig underground passages, and fences are a heavy obstacle for them.
  41. A hedgehog has 36 teeth, which, like humans, can fall out at an old age.
  42. Hedgehogs are a bit blind by nature, but they can distinguish colors very well.
  43. Hedgehogs are not related to porcupines, despite their similarities in body structure.
  44. Hedgehogs have the ability to climb trees. 
  45. In epidemiology, there is the concept of “black hour”. It refers to the number of ticks collected by a hedgehog in an hour of running through the woods. Counting “hourly” helps scientists identify natural tick-borne encephalitis hotspots.
  46. Often owners of country houses, believing that hedgehogs are very fond of milk, leave bowls with this product in the street as a treat for the prickly critters. And indeed, they do drink it, but they don’t feel well afterward. Like most mammals, these animals only eat milk when they are babies.
  47. Sensing a strong and acrid odor, the hedgehog begins to cover its own needles with saliva.
  48. Even the strongest poisons have almost no effect on hedgehogs: mercuric acid, arsenic, potassium cyanide, hydrocyanic acid, etc.
  49. Hedgehogs sleep more during the day because they are considered nocturnal animals.
  50. Male hedgehogs never raise their own offspring.

Spikes and curling up in a ball are the hedgehogs’ natural defense against predators. However, it doesn’t always work – some animals manage to turn a curled-up hedgehog around. A fox, they say, even rolls the hedgehog into the water so that it turns around.

The barbs of some species of hedgehogs can be poisonous. However, this poison is not produced by the hedgehog. The hedgehog smears the needles with venom “confiscated” from toads.

Under the skin, covered from above and on the sides with a needle-like shell, there are longitudinal and annular muscles, whose contraction causes the hedgehog to curl up and take the shape of a prickly ball.

The respiration rate of the hedgehog is 40-50 when awake, and 6-8 breaths per minute when hibernating; body temperature is 34 degrees Celsius, and 2 degrees Celsius when hibernating.

Hedgehogs do not have the best eyesight. However, it is believed that hedgehogs can distinguish colors like humans (unlike all other animals, whose vision is “black and white”). In addition, hedgehogs have very good hearing and sense of smell.

During hibernation, hedgehogs lose a lot of weight, so after waking up, the main task of a hedgehog is to find food, at this time he is insatiable.

All hedgehogs have 36 teeth.

The tail of a common hedgehog is about 3 cm long.

The gestation period of the hedgehog is 7 weeks. There is one litter per year, from 3 to 6 (sometimes up to 7-8) cubs.

The hedgehogs are born blind, with bright pink skin and no needles. Needles (soft at first) begin to appear a few hours after birth. The hedgehog’s eyes open on the 16th day.

The hedgehog is surprisingly resistant to viper venom, although it does not feed on them (unless in captivity). Other poisons, such as arsenic, mercury, opium, and even hydrocyanic acid, have little or no effect on the hedgehog.

Eared hedgehog differs from the ordinary hedgehog by larger ears (3-5 cm). But not only that. Eared hedgehog runs faster than an ordinary hedgehog and when in danger reluctantly curls up into a ball, but more often tries to escape, hissing and jumping. Eared hedgehogs are very resistant to strong poisons and overheating.

It is not true that hedgehogs catch mice (hedgehogs cannot chase the common mouse) and vipers (hedgehogs eat them, but do not hunt them on purpose). It is also not true that hedgehogs milk goats and cows. They really love milk and some of them settle near farms. The hedgehog knows the milking time very well, comes to the farm, and hides in a corner, waiting for the milk to spill on the floor. Then the hedgehog will lick out all the milk. Hedgehogs do not milk.

Never take hedgehogs home! They hardly live in captivity. Besides, hedgehogs are carriers of the most dangerous mites for humans.

Facts About Hedgehogs

Did you know that hedgehogs are mammals? They belong to the family Erinaceidae, which is in the subfamily Erinaceinae. There are seventeen species of hedgehogs, belonging to five genera. These critters are native to parts of Europe, Asia, Africa, and Australia. New Zealand also has them, but by introduction. If you have ever seen one, you’ll be glad you did.

Though they are small mammals, hedgehogs have an excellent sense of smell and can stand up to snakes and even vipers. Although they are related to porcupines, their bodies are more similar to those of shrews and pigs. This is a good thing, because hedgehogs can even defend themselves against snakes and other troublesome insects. In addition, they have the ability to stand up to snakes and eat bugs and insects, which make them very valuable for our ecosystems.

The slender, plump, and furry creatures are often mistaken for pets, but hedgehogs are not very cute. These nocturnal mammals are considered adorable pets. While their videos can make them appear cute, they actually have many dangerous qualities that make them unsuitable as pets. If you’re looking to adopt a hedgehog, it’s best to know the hedgehog facts before buying one.

Most people do not realize that hedgehogs do not live in large groups. They rarely live in groups. They only pair up when they need to mate, and once they’ve done so, they’ll disappear. They are not marsupials and do not hibernate. They also don’t need to hibernate, and they have the ability to stay indoors year-round.

They can be adorable pets, but they have many drawbacks. They don’t like cold weather and can only survive in warmer climates. They also are not very tolerant of cow’s milk, which can cause severe digestive problems and even death. As a result, they are prone to suffering from food allergies. This makes them great candidates for the pet section of the animal kingdom, as they can easily adapt to their surroundings and avoid danger.

The most interesting fact about hedgehogs is that they have a very strong sense of smell. They can detect food up to three centimeters underground. As a result, they can smell a large variety of foods, and their odor is very similar to a human’s. They are primarily nocturnal, and their habitats are generally full of vegetation and are not impacted by humans.

Aside from eating bugs, hedgehogs also have sensitive noses. If you’re a gardener, hedgehogs can easily be a good companion for your pet. If you’re looking for an animal to keep in your backyard, this will keep your plants healthy. Besides, they don’t need much water to survive, so they are easy to care for. There are no invasive animals and they are very safe to eat.

Hedgehogs are not invasive, but they do require special care and are not suited for all households. They are popular pets and can be found in the United States. If you’re planning to buy a hedgehog for your pet, make sure you do your research. It’s important to remember that they’re not invasive and can be harmful to your home, but they’re great for children and aren’t aggressive.

As a pet, a hedgehog can be very destructive and need to be taken care of properly. A good way to care for your pet is to invest in a good quality habitat. You should also make sure your pet is protected against predators. In the wild, hedgehogs are not a threat. They are not afraid of human activity, but you must always be careful with them. If you are unsure of their behavior, you should consult with a professional before doing so.

Hedgehogs are adaptable. While some species live in colder climates, others survive in desert climates. In the coldest regions, hedgehogs may hibernate for up to six months. During this time, they eat. Then they awaken and forage for food, which is why they’re sometimes referred to as “boars” and “sows.”
