Jellyfish are interesting for lots of reasons, one of them being their place on the evolutionary landscape. The first jellyfish-like boast organised tissues and a nervous system. There is nothing that could be described as a brain, but jellyfish neurons work in exactly the same way as vertebrate neurons. So do jellyfish experience anything akin to vertebrate sleep? during the hours of daylight, typically covering around 200 metres an hour.
