在水上

Like the Gila monster, which attacks with venom, inflicting festering but fatal wounds? Or merciless assassin snakes with switchblade fangs as sharp as hypodermic needles and enough poison to kill ten people.

A Diamondback rattlesnake can inject a tracer to track its dying prey and baby snakes fish for trout with their tongues!

A group of scientists at Carnegie Mellon University in Pittsburgh, Pennsylvania, studied insects like water striders and then built a small robot using ultra-lightweight carbon fiber that is also able to walk on water. But they still have some improvements to make — they said the water strider is able to move about 20 times as fast.
