Hedgehog

A hedgehog. 

"The name hedgehog came into use around the year 1450, derived from the Middle Englishheyghoge, from heyg, hegge ("hedge"), because it frequents hedgerows, and hoge, hogge ("hog"), from its piglike snout.[4] Other names include urchin, hedgepig and furze-pig. The collective noun for a group of hedgehogs is array or prickle."
