Etymology

The name ''hedgehog'' came into use around the year 1450, derived from the
Middle English Middle English (abbreviated to ME) is a form of the English language that was spoken after the Norman conquest of 1066, until the late 15th century. The English language underwent distinct variations and developments following the Old Englis ...
''heyghoge'', from ''heyg'', ''hegge'' ("hedge"), because it frequents hedgerows, and ''hoge'', ''hogge'' ("hog"), from its piglike snout. Other names include ''urchin'', ''hedgepig'' and ''furze-pig''.


Description

Hedgehogs are easily recognized by their spines, which are hollow hairs made stiff with

, do not easily detach from their bodies. However, the immature animal's spines normally fall out as they are replaced with adult spines. This is called "quilling". Spines can also shed when the animal is diseased or under extreme stress. Hedgehogs are usually brown, with pale tips to the spines, though blonde hedgehogs are found on the Channel Island of

. All species of hedgehogs can roll into a tight ball in self-defense, causing all of the spines to point outwards. The hedgehog's back contains two large muscles that control the position of the quills. When the creature is rolled into a ball, the quills on the back protect the tucked face, feet, and belly, which are not quilled. Since the effectiveness of this strategy depends on the number of spines, some desert hedgehogs that evolved to carry less weight are more likely to flee or attack, ramming an intruder with the spines; rolling into a spiny ball for those species is a last resort. Hedgehogs are primarily

, though some species can also be active during the day. Hedgehogs sleep for a large portion of the day under bushes, grasses, rocks, or most commonly in dens dug in the ground, with varying habits among the species. All wild hedgehogs can hibernate, though not all do, depending on temperature, species, and abundance of food. Hedgehogs are fairly vocal and communicate through a combination of grunts, snuffles and/or squeals, depending on species. Hedgehogs occasionally perform a ritual called anointing. When the animal encounters a new scent, it will lick and bite the source, then form a scented froth in its mouth and paste it on its spines with its

Olfactory sense

The olfactory regions have not been thoroughly studied in the hedgehog. In mammals, the olfactory part of the brain is covered by neopallium, making it difficult to expose. This difficulty is not insurmountable, as it varies from one species to another. Tests have suggested that hedgehogs share the same electrical activity as cats.


Diet

Although traditionally classified in the now abandoned order Insectivora, hedgehogs are

Hibernation

During hibernation, the body temperature of a hedgehog can decrease to about . When the animal awakes from hibernation, the body temperature rises from back to its normal body temperature.

is 35–58 days. The average litter is 3–4 newborns for larger species and 5–6 for smaller ones. As with many animals, it is not unusual for an adult male hedgehog to kill newborn males. Hedgehogs have a relatively long lifespan for their size. Larger species of hedgehogs live 4–7 years in the wild (some have been recorded up to 16 years), and smaller species live 2–4 years (4–7 in

), compared to a mouse at 2 years and a large rat at 3–5 years. Lack of predators and controlled diet contribute to a longer lifespan in captivity (8–10 years depending on size). Hedgehogs are born blind, with a protective membrane covering their quills, which dries and shrinks over the next several hours. The quills emerge through the membrane after the hoglet has been cleaned, or after the membrane falls off.


Predators

were met with international outrage. Eradication began in 2003 with 690 hedgehogs being killed. Animal welfare groups attempted rescues to save the hedgehogs. By 2007, legal injunctions against the killing of hedgehogs were put in place. In 2008, the elimination process was changed from killing the hedgehogs to trapping them and releasing them on the mainland. In 2022, it was reported that the hedgehog population in rural Britain is experiencing a rapid decline, going down by 30%-75% since 2000.


Diseases

Hedgehogs suffer many diseases common to humans. These include cancer, fatty liver disease, and

. Squamous cell spreads quickly from the bone to the organs in hedgehogs, unlike in humans. Surgery to remove the tumors is rare because it would result in removing too much bone structure. Fatty liver disease is believed by many to be caused by bad diet. Hedgehogs will eagerly eat foods that are high in fat and sugar. Having a metabolism adapted for low-fat, protein-rich insects, this leads to common problems of obesity. Fatty liver disease is one sign, heart disease is another. Hedgehogs are also known to be highly susceptible to pneumonia. Similarly to how pneumonia affects humans, the symptoms for pneumonia in hedgehogs include difficulty breathing and presence of nasal discharge. This is known to be caused by the ''Bordetella bronchiseptica'' bacterium. Hedgehogs uncommonly transmit a characteristic fungal skin infection to human handlers as well as other hedgehogs. This

Between April 2008 and November 2010 on two stretches of road measuring 227 km and 32.5 km there were 133 recorded hedgehog fatalities. Of another 135 hedgehog carcasses collected from throughout Ireland, there were significantly more males than females collected, with peaks in male deaths occurring in May and June. Female deaths outnumbered males only in August, with further peaks in female deaths observed in June and July. It is suggested that these peaks are related to the breeding season (adults) and dispersal/exploration following independence.

s can get their heads stuck in tubes (commonly, toilet paper tubes) and walk around with them on their heads. Owners often refer to this as "tubing" and promote the behavior by supplying lean tubes. Most owners are considerate enough, however, to cut the tubes lengthwise to prevent the hedgehog from remaining trapped against its will. Curiously, some hedgehogs still knowingly get themselves stuck for hours.
