Question: What is a nerve net

Jasmine answered on 14 Nov 2018:

Humans have a nervous system connected to a brain, our nerves are all over our body and they pick up senses from the environment and send messages to the brain. Jellyfish also have a nervous system which picks up senses from the environment but they don’t have a brain so they don’t have a nervous system as such, that’s why it’s called a nerve net. I hope this answers your question, it’s kind of hard to explain.
