Hedgehogs are small mammals covered in spines, which protect them from potential predators.
These spines, also known as quills, are actually modified hairs and are composed of keratin, the same material that makes up our fingernails.
These cute little critters are known for their peculiar appearance and curious behaviour; they have a rounded body and short legs, which make them look like little balls of spines on the move.
Although hedgehogs are mainly nocturnal, they can also be seen during the day in search of food.
They are omnivorous, which means that they feed on a variety of foods, such as insects, worms, fruits and even small reptiles.
One of the most interesting characteristics of hedgehogs is their ability to curl up into a ball when threatened, exposing only their spines, which makes them a difficult target for predators.
Hedgehogs also have a highly developed sense of smell, which helps them find food and detect possible dangers, and they have decent eyesight and hearing, although these are not their keenest senses.
They are solitary animals by nature, but do not mind sharing their territory with other hedgehogs as long as there is enough food and shelter for everyone.
They are quite independent and are not usually common pets, although some people keep them in captivity under specialised care.
They make excellent garden helpers, as they feed on all insects that attack vegetables, such as spoonbills and snakes.
