The Wonderful Blue Bottle Jellyfish – The Man Of War

Everybody must have seen at least once a jellyfish – no matter if on a picture or he had a live experience it. That person has witnessed the majesty of the most attractive sea inhabitants. An interesting fact about the jellyfish body is that it consists of 90% water and 10% jelly substance from where their name comes. Jellyfishes do not only possess an amazing outside look, but they also have a interesting anatomy, however for the regular person the most attractive part of a jellyfish are its body contours and colors. And for the people who care about the outside look of the jellyfish we can recommend them to see the Blue bottle jellyfish which is a truly beautiful and interesting sea inhabitants.

The name Blue bottle jellyfish is mostly used in Australia and New Zealand and the name is based on the color and form of the jellyfish when on the coast. Almost anywhere else in the world the Blue bottle jellyfish is known as the “Portuguese Man o’ War”, because according to many people the jellyfish looks like a battleship which Portuguese used in the past. The most remarkable fact about the Blue bottle jellyfish is that it isn’t a monolith organism. It is made by a different number of zooids which have a specific role and together they create the organism.

The Blue bottle jellyfish eats mainly small ocean creatures like fish, plankton and others. The first thing which the Blue bottle jellyfish does when capturing a creature is to envelope it using its tentacles and afterwards inject a venom in it, which has a paralyzing effect and therefore will render the prey unable to move or fight back. Not many jellyfishes can use their tentacles to envelope their prey, but the Blue bottle jellyfish has very strange tentacles. Their tentacles are covered with small barbed-wire-like hooks which allow them to easily attach to the prey and disable its movement.

The Blue bottle jellyfish is also a threat to humans, but there is no report in which a living person has died because of a Blue bottle jellyfish sting. Of course if you get somehow stung by one you should immediately seek help from a doctor. Or if there is no medical center nearby clean the stung place with cold water without laying a finger it and later apply ice packs to the stung place to decrease the pain.

Another interesting thing that we know for the Blue bottle jellyfish is how it moves. It doesn’t move like the other jellyfishes which use the pulsations of their body to move them forward. Instead the Blue bottle jellyfish relies mainly on water currents and wind. The Portuguese Man o’ War stays most of the time on top of the ocean surface, but if it feels threatened it can deflate its body and quickly go under water.

Keeping Jellyfish In Home Aquariums

What is the first thought which comes up to your mind when you hear about jellyfish. Yes, it is certainly something quite mysterious since the jellyfish are announced to be one of the most enigmatic creatures in seas and oceans. Actually, the first information about the jellyfish’ existence is more than 4000 years old but just 50 years ago, we hardly knew anything about these creatures. Perhaps, if you are over the age of 30 you remember that it was only possible to see jellyfish in the big and public aquariums. They used to be one of the biggest attractions, actually! But nowadays, jellyfish could easily become your new pet! It is great, isn’t it?

But nowadays, it is very easy to purchase a jellyfish and look after it in your own aquarium. What a sudden change? How could things have altered for 50 years? Could the jellyfish have evolved? Hmm, it is definitely not a good guess since evolution is a process which takes millions of years, not a couple of years! The answer is somewhere else.

The truth is that we are already able to have “jellyfish pets” thanks to the great scientific progress. We already know what the jellyfish eat, what temperature of the water they like, even how they “give birth”. So, it is not surprising that looking after a jellyfish is already effortless and absolutely possible. You could even take care of several jellyfish pets depending on the size of your aquarium- it is your only limit!

Yes, you read it right: pets! It used to be the snakes some time ago and now it is the jellyfish. The surveys show that the number of people purchasing jellyfish as pets is increasing steadily! Perhaps, it is a fad…or not! Only the time will show us. But whatever it is, it seems like the jellyfish will soon become an obsession for many people.

The conclusion is that if you like to experiment, you should not think twice before going to the pet-shop and purchasing a couple of these wonderful maritime creatures. But if you like to think every next step through, you might need some more time to decide. However, I will try to help you by saying that looking after pets like jellyfishes is much cheaper than you probably need. All you need to do is give them food and keep the levels of oxygen favorable. And the best thing is that it is exactly as easy as it sounds! There is really nothing you have to worry about. Furthermore, you can always return the pets if you think that you cannot handle with such a “responsible task”. However, I am sure you won’t want to do it since looking after a jellyfish will not take more than 10 minutes of your day!

Jellyfish are easy to keep as pets today due to new technologies and information. It’s easier then you may think. Start yourself off with the Moon Jellyfish. Visit our website to learn more about setting up a Jellyfish Aquarium.
