　　異溫動(dòng)物、變溫動(dòng)物會(huì)冬眠，這些動(dòng)物包括蛇、倉(cāng)鼠、青蛙等。冬眠又叫冬蟄，它可分為主動(dòng)式冬眠、被動(dòng)式冬眠，后者的代表動(dòng)物就是松鼠。誘發(fā)冬眠的因素有很多，比如溫度下降、環(huán)境短缺等，還有專家認(rèn)為白晝縮短會(huì)導(dǎo)致動(dòng)物內(nèi)部產(chǎn)生變化，從而誘發(fā)冬眠。

　　什么動(dòng)物冬眠

什么動(dòng)物會(huì)冬眠

　　異溫動(dòng)物和變溫動(dòng)物冬眠

　　在大自然中有冬眠習(xí)慣的動(dòng)物有非常多，比如蛇、倉(cāng)鼠、青蛙、松鼠等等，這類動(dòng)物根據(jù)它們的體質(zhì)可以分為異溫動(dòng)物和變溫動(dòng)物冬兩類，恒溫動(dòng)物則沒(méi)有冬眠的習(xí)慣。

　　冬眠介紹

　　冬眠是一種生物學(xué)現(xiàn)象，它又可以被人們稱作為冬蟄，一些動(dòng)物為了減少冬天時(shí)候體內(nèi)能量的消耗，就會(huì)選擇進(jìn)入長(zhǎng)時(shí)間的睡眠，一些動(dòng)物是主動(dòng)式冬眠，但一些卻是被動(dòng)的，比如倉(cāng)鼠等等。

　　誘發(fā)冬眠行為的因素

　　誘發(fā)動(dòng)物冬眠的因素主要都是外在的，比如溫度下降、環(huán)境短缺等等，不過(guò)也有一些專家認(rèn)為在白晝逐漸縮短的時(shí)候，動(dòng)物內(nèi)部的激素水平或者是其他的內(nèi)部因素出現(xiàn)了變化，從而誘發(fā)冬眠的行為出現(xiàn)。
