The underwater world is full of secrets and mysteries. One of the most mysterious creatures is jellyfish. Their body is 90% or more water. They live in salty seas and oceans. Translucent bodies seem to almost dissolve in water. There are specimens ranging in size from a few millimeters to several meters. Large individuals are of great interest.
Hairy Cyanea, 2.3 m
The body of a jellyfish is up to 2.3 m in size, and the tentacles are up to 37 m. They hide at a depth, so they rarely pose a threat to humans. Its poison causes a burn, but no more. Most often, giants are found in the Atlantic.

Another name is Lion’s Mane. The size of the dome can reach 2 m, and weight – 200 kg. They look like huge hairy balls. Giants often tangle the nets of fishing boats. They have an allergenic poison. If a person has a reaction to this substance, then he can die.
Medusa Hriosara (Sea nettle), 1 m
Body size – up to 1 m, tentacles – up to 4 m. Her bites leave scars on the body. However, the poison is harmless to humans. If the tentacles are torn off, they will be able to exist separately for a long time and burn those who get in their way.

Australian sea wasp, 0.45 m
An insidious and dangerous creature that lives off the coast of Indonesia and Australia. Its venom can cause a heart attack in humans. At the same time, the 45-cm body of the jellyfish is transparent, it is quite difficult to notice it in the water.

Medusa Aurelia, 0.4 m
Jellyfish with an almost transparent body. It has a size of 40 cm. It is safe for a person – it can only cause a slight burn. It is used to prepare exotic dishes. Because of the mouth cavities hanging like ears, she is called Aurelia Eared.
Jellyfish Portuguese boat or Physalia, 0.25 m
The jellyfish is named so due to the fact that its appearance resembles a sailboat. The body size is small – 25 cm, but long tentacles are hidden under it – up to 50 m long. The dome is painted in an unusual purple or blue color. However, beauty is deceiving – this is one of the most dangerous jellyfish. Its poison affects all body systems, because of which a person quickly drowns.
Medusa Pelagia, 0.12 m
Another name is Nightlight. This is due to the fact that when in contact with various objects, the body of the jellyfish begins to glow.
