Hedgehogs roll into a tight spiny ball when threatened, tucking in the furry face, feet, and belly. [7] The hedgehog's back contains two large muscles that direct the quills.

Like all other hedgehogs Erinaceus is nocturnal and seeks shelter in shrubs and burrows during the day. [6] The common defense mechanism is to roll into a ball with the spines facing outward. The action is done because of excess loose skin on the back of hedgehogs allows them to pull it around the rest of their body forming a ball.
The four-toed hedgehog (Atelerix albiventris), also known as the African pygmy hedgehog, is a species of hedgehog found throughout much of central and eastern Africa. Populations tend to be scattered between suitable savannah or cropland habitats, avoiding forested areas. The species common name is derived from the number of toes found on its ...
