Hedgehogs are spiny mammals of the subfamily Erinaceinae. There are seventeen species of hedgehog in five genera, found through parts of Europe, Asia, and Africa, and in New Zealand by introduction. Like many of the first mammals, they have adapted to a nocturnal way of life. Hedgehogs’ spiny protection resembles that of the unrelated porcupines, which are rodents. They have become pests in areas such as New Zealand, where they have been introduced. Due to lack of predators, they cause immense damage to native species including insects, snails, lizards and ground-nesting birds, particularly shore birds. They can also suffer many diseases common to humans, such as cancer, fatty liver disease and cardiovascular disease.
