So scientists have cleverly decided to call it a nerve net.

因此，科学家们聪明地决定称其为神经网络。

This nerve net allows jellyfish to sense its environment and reflexively make changes.

这种神经网络使水母能够感知环境并反射性地做出改变。

The nerve nets of jellyfish and related species is basically nature's first draft of a nervous system.

水母及其相关物种的神经网络基本上是自然界神经系统的第一张草图。

Through their nerve nets, they can sense the temperature, salinity of the water, oxygen concentration, gravity, ocean currents and more.

通过它们的神经网络，它们可以感知水温、盐度、氧气浓度、重力、洋流等等。

Instead of a brain, hydras have nerve nets, the most basic nervous systems in nature.

水螅没有大脑，而是拥有神经网络 ，这是自然界中最基本的神经系统。

The rudimentary nerve net and nerve ring seem simple when compared to our large brain, but it's a mystery how jellyfish manage behaviours like courtship without a master controller.

与我们的大大脑相比，基本的神经网络和神经环似乎很简单，但水母如何在没有主控制器的情况下管理求爱等行为却是一个谜。
