Hedgehog
Hedgehogs are named after their pig-like habit of rooting through the undergrowth for food. They are quite noisy and can often be heard snuffling and grunting during their activities.

Hedgehogs roll into a tight ball when they require defensive measures against predators. In this way, all vulnerable areas of the body are hidden, leaving the predator with a circle of quills, or spines.

Hedgehog quills are not barbed or poisonous. However, hedgehogs will apply a foamy saliva to their quills.

The Hedgehog is a mammal and it can grow to the size of six to nine inches long. The average lifespan of hedgehog is ten years and it reaches sexual maturity between the ages of 1 and 2.

The hedgehog is solitary except during breeding season. However, when several hedgehogs are in an area, some sort of pecking order does seem to fall into place. They make a variety of snuffling and snorting vocalizations and also clack their teeth.

The hedgehog hibernates in winter. It feeds as much as possible during the fall, and in October it builds an extra-thick nest in which to spend the winter. It prefers to build its nest in woodpiles, compost piles, and haystacks.

This hedgehog is about 20 cm in length, and lives in woodland, farmland, and suburban areas. It is nocturnal, and if alarmed will roll itself into a ball, protecting itself against potential predators with its spines.
