(1) These ├ö├ç├┐resistance├ö├ç├û characters include such obvious traits as the quills on a porcupine or the puffing of a puffer fish.(2) The quills are so lightly fixed to the porcupine 's body that they are easily detached and left imbedded in the attacker.(3) They also sometimes roost in the burrows of other mammals such as hedgehogs, porcupines , and aardvarks.(4) Burrows which have been abandoned may be used for shelter by bats, ground squirrels, hares, cats, civets, hyenas, jackals, porcupines , monitor lizards, owls and warthogs.(5) Hedgehogs, porcupines , and some Old World salamanders sport protective spines.(6) Most birdwatchers come to see the rare brown-necked parrots that frequent the area, but there's also a hide where you can see porcupines and bushbuck.(7) Like elephants, hippos and bushpigs, porcupines are nocturnal crop raiders.(8) Other South American rodents include guinea pigs, chinchillas, and New World porcupines (one species of which has dispersed into North America).(9) As is the case with North American porcupines , the quills are loosely attached but can't be thrown or otherwise projected.(10) Other animals photographed included elephants, sun bears, porcupines , clouded leopards, wild dogs, and panthers.(11) The ermine's diet consists primarily of mice, but they also prey upon cottontails, small hares, porcupines , squirrels, pikas, and rats.(12) TWO little boys giggle as they play hide and seek among hundreds of filthy cages packed tight with civet cats, dogs, porcupines and squirrels.(13) Whole lions at Ôö¼├║5,000 a head, antelopes, porcupines , goats, cane rats and large, live snails - all from West Africa - were also candidates for the dinner table.(14) Despite the fact that they burrow underground like moles, and have big front teeth like rats have, naked mole-rats are more closely related to porcupines and guinea pigs than to moles or rats.(15) They have to contend with elephants, hippos, bushpigs, porcupines , vervet monkeys, baboons and birds which are after their crops.(16) Eight other species, including pacas, pacaranas, spiny rats and porcupines , also steal Brazil nuts stored by agoutis.
