科學圖說 Scientific introduction

這隻凱門鱷是2016年寒假在厄瓜多爾的亞馬遜雨林裡拍攝的。在照片中,可以看到鱷魚身上有很多蚊子,有些人可能會問:「鱷魚全身遍布堅厚的鱗甲,蚊子怎麼能穿透鱷魚的鱗甲呢?」大家可不要小看蚊子,這種蚊科昆蟲,不但能精確找到皮膚暴露、毛細血管密集的眼瞼部位,還能靠牠的刺吸式口器取食凱門鱷的血液。大自然總是這麼奇妙,鱷魚雖然能攻擊人類,但是得受蚊的折磨!這隻倒楣的鱷魚已經被群蚊圍攻了!


This Caiman crocodilus was photographed during 2016 winter break in the Amazon rainforest of Ecuador. In this photograph, a caiman is covered in mosquitoes. Some people may ask, “How can a mosquito penetrate a caiman’s hard, thick scales?” Do not underestimate the mosquito. These insects of the Family Culicidae can find areas of exposed skin where capillaries are concentrated, such as the eyelids, then use their piercing- sucking mouthparts to obtain blood. Nature is really amazing. Although caimans can attack humans, they also have to deal with being tortured by black flies, such as this unfortunate individual.
