One of my favorite creatures of the sea is the Jellyfish! They are so magical and beautiful! I love the way the move in the water and how they are all so different and original.
Fact #1 There are over 200 known species of jellyfish, True jellyfish and many others. Examples of true jellyfish include Lion’s Mane that is known to be the biggest, Moon Jellies, Sea Nettles and Blue Jellies among others. Those that are not true jellyfish like the Craspedacusta Sowerbii, are known so because they only thrive in fresh water. The history of jellyfish dates back to over 650 million years ago and is a story much longer than that of dinosaurs.
Fact #4 Jellyfishes have no brain, no blood and no nervous system. Their senses are primitive and consist of a neural net, eye spots that can sense light from dark, and chemosensory pits that help them identify potential prey.
Fact #9 Jellyfish are not actually classified as ‘fish’, some people prefer to refer to them as ‘sea jellies’. They do not have gills (or lungs)
