#昆蟲與蜘蛛
科學圖說 Introduction
寬大布丹蛛的雌蛛,原先偽裝平貼於樹枝,靠近拍攝時,牠霎那間捕食了一隻蒼蠅。透過鏡頭,可見其捕食過程。寬大布丹蛛的眼有敏銳的視覺,而布滿在步足上的毛能感知微小的震動,使蜘蛛精準感知獵物的位置。待鎖定目標後,蜘蛛一瞬間撲向獵物並迅速以螯肢上的「毒牙」將毒液注入獵物體內。
A female Asian huntsman spider (Bhutaniella latissimi), which was camouflaged on a tree branch, suddenly moved, capturing a fly, around the time it was photographed. This predation process was observed through the lens. This spider has keen vision and hairs on its legs for perceiving slight vibrations to accurately locate prey. Once it has locked in on a target, it springs into action, pinning it down and injecting it with venom.
