(1) Can you think of any other animals that roll into a ball for defence as well as an armadillo or hedgehog ?(2) He was, in short, a hedgehog living in a world populated with foxes.(3) The hedgehog is an old world mammal that has possibly changed little over a million years.(4) A hedgehog isn't a hedgehog if it doesn't have any needles!(5) So far as I know the hedgehog never returned so I presume he, or she, got the message.(6) They still refer to me as ├ö├ç├┐hoggie├ö├ç├û, short for hedgehog , because I am apparently ├ö├ç├┐prickly but cute.├ö├ç├û(7) By the time of spring, his hedgehog had put on so much weight that his short paws were hardly visible beneath his stuffed underside.(8) A puppy came crawling out of the bath, its coat was so filthy it looked like a hedgehog .(9) It is said that if the fox finds the hedgehog near water it can coax him from his defensive shell by rolling him with it paw until finally the hedgehog is in the water and forced to come out to save himself from drowning only to face a worse fate.(10) The mammals the researchers studied were the platypus, echidna, opossum, wallaby, hedgehog , mouse, rat, rabbit, cow, pig, bat, tree shrew, colugo, ringtail lemur, and humans.(11) Many species of hedgehogs can roll up into a ball, hiding all vulnerable areas of the body under the protective spines.(12) The study found that while some species, including hedgehogs , voles, shrews, dormice and hares, are generally declining in rural areas, their populations are rising in towns, cities and suburbs.(13) Suburban householders report large numbers of hedgehogs , voles, shrews, dormice and hares.(14) Animals co-habiting in the woods include field mice, grey squirrels, hedgehogs and three roe deer.(15) The public is being asked to survey kingfishers, skylarks, water voles and hedgehogs so that as much information as possible can be gathered.(16) Baby hedgehogs are born with short, soft spines that don't harden for several weeks, and baby humans cannot walk on their own for the first couple of years.
