豪猪和刺猬不是亲戚,豪猪是啮齿目的1科,而刺猬是属于猬形目。
1、豪猪:
豪猪科是啮齿目的1科。通科豪猪。共3属11种。豪猪科动物以棘刺闻名,棘刺有保护御敌作用,最长可达35厘米。遇敌时棘刺竖立抖动,发出沙沙声响,紧急时能后退。
再有力地扑向敌人将棘刺插入其身体。豪猪体型肥大,最大者体长达70厘米以上;头小、眼小,四肢短粗。
背部与尾部生有长而硬的棘刺,此系防御天敌的重要器官。头骨较细小,颧弓不外扩,而鼻腔却甚膨大,有20枚齿根很浅的牙齿。
2、刺猬:
刺猬是属于猬亚科的一类猬形目哺乳动物的统称,共有5个属。其中猬属的刺猬分布最普遍,广泛分布在欧洲、亚洲北部,在中国的北方和长江流域也分布很广。
中国最常见的有黑龙江刺猬等。刺猬在苏南民间又被叫做偷瓜獾,体肥矮、爪锐利、眼小、毛短,浑身有短而密的刺,刺猬在夜间活动,以昆虫和蠕虫为主要食物。

扩展资料:
刺猬性格温顺,有些品种只比手掌略大,因而在澳大利亚 和英国有人将它当宠物来养。普通刺猬不易作为宠物饲养。
作为宠物的刺猬是由普通刺猬和非洲的四趾刺猬杂交培育的,不冬眠,个头较小,不耐寒。家庭饲养杂交的刺猬可以自配饲料。
以肉类下脚、粮食及副产品、青菜等按比例配合饲养。另外,毛毛虫、甲虫、蜗牛、蚯蚓等小动物和水果也可喂养。

两者的亲缘到目组时就分开了,豪猪是鼠类祖先进化,为啮齿目豪猪亚目动物,刺猬是鼩鼱祖先进化,为食虫目猬亚目猬科和无毛猬科的物种总称。
动物名称:豪猪 HAO ZHU
科:豪猪科
拉丁名:Hystrix hodgsoni
英文名:Porcupine
豪猪是啮齿目动物中的一类。身体肥壮,自肩部以后直达尾部密布长刺,刺的颜色黑白相间,粗细不等。豪猪白天躲在穴中睡觉,晚间出来找食,喜食花生、番薯等农作物。受惊时,尾部的刺立即竖起,刷刷作响以警告敌人。
刺猬 cì wèi
Erinaceus europaeus
地方名普通刺猬,英文名Hedgehog。猬科。
猬亚科 Erinaceinae

食虫目猬科刺猬亚科的通称。又名刺球。体背和体侧满布棘刺,头、尾和腹面被毛;吻尖而长,尾短;前后足均具5趾,跖行,少数种类前足4趾;齿36~44枚,均具尖锐齿尖,适于食虫;受惊时,全身棘刺竖立,卷成如刺球状,头和4足均不可见。分布于亚洲、欧洲、非洲的森林、草原和荒漠地带。中国有2属4种。普通刺猬栖山地森林、草原、农田、灌丛等,昼伏夜出,取食各种小动物,兼食植物,有时为害瓜果。冬眠。
两个关系不算近。豪猪是啮齿目动物,和鼠类关系较紧。而刺猬则是食虫目动物。
