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.
