來玩球吧 Let’s Play Ball

科學圖說 Scientific introduction

一隻毛垛兜跳蛛的微小若蛛，正銜著一粒蟲卵，頭胸部轉向鏡頭用單眼打量著，看起來有如叼著球望向主人，以眼神示意邀請主人陪牠一起戲玩的小狗。跳蛛視力優秀，不結網並仰賴視覺捕捉獵物。發達的前中眼會反射相機的閃燈，眼睛中明亮的部分是所謂的「眼神光」，投影出相機光源的形狀。

A Ptocasius jumping spider is holding an insect egg. Its cephalothorax is pointed toward the lens. Its expression appears like that of a puppy looking up at its master, and hoping to play. Jumping spiders have excellent vision. They do not spin webs, but rather use their sense of sight to capture prey. The well-developed anterolateral eyes reflect the flash of the camera. The brightness of the eyes is referred to as “catch light”, and is a projection of the camera’s light source.

以小欺大 The Weak Preys on the Strong

科學圖說 Scientific introduction

在動物的世界裡，弱肉強食、適者生存的戲碼不斷在上演。蜘蛛就是捕食昆蟲的翹楚，有些靠著結網等待獵物自己送上門，但也有蜘蛛靠著敏銳的動作伏擊獵捕。一旦捕獲獵物後，用毒腺分泌毒液制伏，簡單將獵物變成囊中物。獵捕對象的體型可能比蜘蛛大上好幾倍，是名符其實的以小欺大。

In the animal world, the weak becomes the prey of the strong. Only the fittest survive. Spiders are very adept at preying on insects. Some spiders spin a web and wait for their prey to come to them. Some make use of stealthy and quick movement to capture their prey. As soon as they capture their prey, they secrete poison from their poison glands to subdue it. In some cases, the prey may be many times larger than the spider. This is the idea behind the title given to this image.
