鱷魚冬眠罕見畫面曝光凍在水裡、只有鼻子露出冰面
沒想到鱷魚還會把自己凍成冰棒!在美國部分地區,如果突然遭遇寒流,就有機會看到一些鱷魚被凍在了冰裡,如同被冰凍魔法囚禁在冰牢中。然而它們並不是被凍死了,這只不過是它們熬過寒冷天氣的小技巧。
為了能夠抵抗突然來襲的低溫,大多數鱷魚的反應是從水中爬出來,跑到岸上曬太陽。
但也有部分鱷魚會選擇進入一種類似冬眠的狀態,稱為brumation。它們會選擇一個舒適的地點,繼續躲在水下,同時讓身體進入低耗模式,像是進入了深度睡眠,然後把鼻子露出水面,以確保水面凍結後自己不會窒息。
之後鱷魚就會靜靜地趴在冰面下,只把鼻子放在外面,然後一動也不動幾乎完全靜止。但這種模式並不能長久運行,一般來說氣溫會很快回升,水面解凍後,它們就復活過來了。
所以如果在野外看到這一幕,千萬別試圖把鱷魚拉出冰面更不要隨意觸碰,指不定人家有起床氣,張嘴就會咬上一口。
