Blue Jellyfish

Jellyfish come in a vast array of colors and sizes. There are jellyfish which are purple, green, yellow, white, opaque, translucent and blue. The most popular blue jellyfish would have to be the blue bottle jellyfish which is also known as the portuguese man of war, which is not really a jellyfish at all. This blue beauty is carnivorous and feeds on smaller fish and other small marine critters. Another popular blue jellyfish to read about is the Blue Blubber Jellyfish. For the remainder we will discuss the blue bottle, or man of war, but don't miss the Blue Blubber Jellyfish either.

Blue bottle jellyfish surround their prey with their stinging tentacles and release a poison into the flesh of their victims which then paralyses the victim before it is consumed by the jellyfish.

Blue bottle jellyfish are extremely adept at adhering their tentacles to their prey by using a series of long barbed hooks which hook into the skin allowing the tentacle to attach. When these tentacles attach to human flesh they release a poison using their nematocysts and any irritation to the skin even after the tentacle has been removed will cause more venom to be released. The best treatment if you have been stung is to wash the area without actually physically touching it. These blue bottle stings are extremely painful but have not yet caused any fatality in Australia or New Zealand.

Blue bottles are usually blue or though they have been found to have a pink hue from time to time. The body of the blue bottle jellyfish can range anywhere from 3 up to 15 cms and the blue bottles tentacles can drift anywhere from 15cm right up to a huge 10 metres below them. The blue bottle jellyfish gets its name not only from the fact that it is the color blue but also because of its appearance when it is stranded on the beach. The blue bottle jellyfish indeed does look alot like a blue bottle when stranded on the beach.

This jellyfish is only known as the blue bottle primarily in Australia and New Zealand and in other parts of the world this jellyfish is known as the Portuguese Man-O-War. It is said to look like a Portuguese battleship with a sail by some people. This blue jellyfish is made up of a combination of zooids. The blue bottle jellyfish is not actually a single organism but is instead made up of a number of zooids. In these zooids every one of them is assigned a particular duty just as it would be like if it were an animal that is a member of a pack. In example there are a number of these zooids whose sole duty in life is to make up the stinging tentacles of the jellyfish and other zooids will be tasked specifically with other lifelong duties such as making up the feeding tentacles.

These jellyfish can be quite alluring to look at and may entice people who aren't familiar with their danger to touch them. As with all other jellyfish any contact with the jellyfish should be avoided as much as possible as agitation of one of these jellyfish will result in a nasty sting which will cause pain and irritation.
