The Jellyfish is an amazing creature and has 200 different types of species. These marine animals come in varying sizes, and are from a few centimeters in diameter to more than two meters. The jellyfish has a bell shaped body with tentacles hanging below the main body. The size of a jellyfish is measured in terms of the bell diameter and length of its tentacles. The length of a jellyfish varies from a few centimeters to more than seven feet.

The largest known species of jellyfish is the Lion's Mane Jellyfish. It prefers cold waters of the ocean and is mainly found in the boreal waters of the Arctic, northern Pacific oceans and northern Atlantic. The Lion's Mane found in the Arctic is one of the longest known animals and the largest recorded specimen is 120 feet in length and the bell body has a diameter of 7 feet and 6 inches. This was found washed ashore in Massachusetts Bay in 1870.

The Lion's Mane is a common species of jellyfish and packs quite a sting. These stings are seldom fatal, but are toxic and can cause severe pain and burns. Only one person has been reported to have been killed by this type of jellyfish, but still this species is considered potentially dangerous. The bell body of this jellyfish is capable of attaining a diameter of 8 feet, but this species comes in varying sizes. The ones in the northern counterpart are much bigger in size then the ones found further south. The southern ones have only up to a bell diameter of 20 inches. The Lion's Mane found in the northern oceans have tentacles which trail as long as 100 feet in length. The tentacles of this jellyfish is extremely sticky and come grouped in eight clusters. Every cluster has 65 to 150 tentacles, in a series of rows. The bell body has an appearance of an eight-pointed star, as it is divided into eight lobes.

The color of the Lion's Mane jellyfish depends on its size. The larger ones come in dark purple and vivid crimson colors. The smaller specimens usually have shades of lighter orange or tan. This jellyfish is so named because its thick cluster of tentacles look similar to a lion's mane.

Another species of jellyfish which comes close to the size of the Lion's Mane is the Nomura's jellyfish. The bell body grows up to a diameter of 2 meters and weighs almost 220 kilograms. These jellyfish mainly resides in the water between China and Japan, and is found more in the Yellow sea and the East China sea.
