　　某些生活在高緯度地區(qū)的蝙蝠會(huì)冬眠，由于天氣寒冷，許多動(dòng)物和昆蟲(chóng)都不出來(lái)活動(dòng)，蝙蝠也就要進(jìn)行冬眠。蝙蝠冬眠的時(shí)間一般長(zhǎng)達(dá)6個(gè)月，冬眠期間蝙蝠依靠自身的脂肪來(lái)提供能量，它們會(huì)通過(guò)降低體溫和減慢新陳代謝來(lái)減少能量的消耗。

蝙蝠會(huì)冬眠嗎

　　生活在溫帶地區(qū)的蝙蝠在寒冷空氣來(lái)臨時(shí)，一部分會(huì)像鳥(niǎo)類(lèi)一樣進(jìn)行長(zhǎng)時(shí)間的遷徙，到南方過(guò)冬，一些留在原地的蝙蝠就要在嚴(yán)冬時(shí)節(jié)進(jìn)入冬眠狀態(tài)。蝙蝠冬眠時(shí)，不會(huì)去外界找尋能量供應(yīng)，一般都是自身的脂肪提供能量，冬眠時(shí)間在6個(gè)月左右。

蝙蝠會(huì)冬眠嗎

　　蝙蝠冬眠時(shí)會(huì)降低體溫，減慢新陳代謝來(lái)減少能量的消耗，其心跳速度會(huì)下降到每分鐘十下。蝙蝠冬眠之后，體重會(huì)下降很多，幾乎下降到原來(lái)的一半，冬眠雖然對(duì)蝙蝠生存有著重要影響，但給蝙蝠帶來(lái)的害處也是有的。

蝙蝠會(huì)冬眠嗎

　　根據(jù)科學(xué)家研究表明，蝙蝠冬眠前積累足夠多的脂肪可以盡可能地縮短冬眠時(shí)間和減輕冬眠帶來(lái)的副作用。生活在亞熱帶和熱帶地區(qū)的蝙蝠一半不會(huì)進(jìn)行冬眠，那里全年氣候溫和，食物供應(yīng)充足，不需要進(jìn)入冬眠狀態(tài)。
