Revised Answer (140 words):

The professor mentions that dragonflies are among the most successful predators on Earth, with a 95% success rate in capturing their prey. The professor explains two reasons why dragonflies can capture prey more efficiently, resulting in their 95% success rate. Firstly, the lecturer discusses the dragonfly's compound eyes. Dragonflies possess compound eyes, which are highly advantageous as they enhance color vividness and provide a 360-degree field of vision. This enables them to easily spot mosquitoes against the contrasting blue sky. Furthermore, dragonflies are said to have unique adaptations that assist them in capturing moving prey. Their brains can detect the speed and path of their prey, allowing them to predict where it will be at the moment of capture. This helps dragonflies adjust their position and flight path to perfectly intercept and catch their prey in midair.
