- The Latin for ‘hedgehog’ is Erinaceus which means ‘spiky wall’ .
- The Irish word for hedgehog is ‘gráinneog’ – meaning ‘horrible one’!
- Hedgehogs occasionally perform an unusual ritual of ‘self-anointing’. This occurs when they come across a strong or an unfamiliar scent. The hedgehog will lick and bite the source and then form scented frothy saliva which it pastes over its spines with its tongue. Some believe that this ‘anointing’ camouflages the hedgehog with the scent of the area and possibly provides a poison or a source of infection to predators that come into contact with its spines.
- Apart from the nine species of bat, the hedgehog is the only Irish mammal that undergoes true hibernation usually from October to March.
