Hedgehogs are nocturnal animals and usually only come out at night having spent all days sleeping in nests, bushes and other foliage. The hedgehog has a thick spine coat which they use to protect themselves by curling up into a ball when threatened, which provides an impressive defense mechanism against predators. Each hedgehog has around 5000 spines and each year the spine coat is replaced with a new one. Each spine will drop off and a new one will grow in its place.
The adorable creatures have very weak eye sight and largely rely on their sense of smell and hearing to hunt for food and find shelter. They have an unusually long nose which helps them sniff out any sources of food when foraging. Hedgehogs are usually solitary creatures and pair up only to mate, after which the male will separate from his new family afterward and will have no part in rearing the young.
