Lion’s Mane Jellyfish

Ok not human at all. Lion’s Mane Jellyfish are as old as dinosaurs and still around. They are the largest jellyfish in the world. They have been around for over 650 million years and are one of the oldest surviving species on Earth.

The lion’s mane jellyfish can attain enormous size. In fact, the largest Lion’s Mane jellyfish is not merely the largest species of jellyfish in the world; it is the largest animal in the world. The one specimen of Lion’s Mane which was found in Massachusetts Bay in 1870 was over 7 feet in diameter and its tentacles were longer than 120 feet in length.

The bell of the Artic Lion’s Mane is known to be able to grow up to 8 feet in diameter, and their tentacles can acquire the length of 150 feet. That is much longer than blue whale, which is generally thought to be the largest animal in the world.

They have hundreds of poisonous tentacles that it used to catch passing by fish. it then slowly drags in it’s prey and eats it. Their sting can cause humans death or severe burn/ burning sensations.


They are found in the freezing cold waters of the Arctic Ocean and Northern Pacific Ocean during the coldest months of the year. They rarely descend below 42 degrees latitude and are not found in the southern hemisphere at all.

The largest specimens of the lion’s mane jellyfish are a dark crimson in color. As their size reduces, the color becomes lighter until it is light orange or tan.

Lion’s mane jellyfish has a number of oral arms near the mouth to facilitate transporting the food to the jellyfish’s mouth. Lion’s Mane, like most other species of jellyfish, is carnivorous and feeds on zooplankton, small fish, and ctenophores. Lion’s Mane jellyfish is also cannibalistic and feeds on other jellyfish like moon jellies. The predators of the lion’s mane jellyfish include seabirds, larger fish, other jellyfish species and sea turtles.
