The biggest species of Jellyfish known to man is the Lion’s Mane Jellyfish, also known as the Giant Jellyfish or the Arctic Red Jelly. It is easily recognized by its massive amount of tentacles which resembles a stringy mass of hair and its red coloration. This Jellyfish tends to live in colder waters around the arctic but is commonly found in the English Channel and off the coast of Scandinavia.
Some Lion’s Mane Jellyfish are thought to grow to the size of a Blue Whale, the largest living animal in the world, however, the size of this creature can vary.
