Blue Bottle Jellyfish
Below the main body of the blue are its tentacles. They are an average of one meter in length, but under certain conditions are known to grow as long as 50 meters. Each of these tentacles is lined with numerous nematocysts that contain the highly toxic venom of the blue bottle. When the tentacles come in contact with a prey, the nematocysts are activated and the toxin is infected into the flesh of the prey. It is sufficient to kill small prey like shrimp and young fish. The tentacles then help transport the food towards the digestive polyps, the gastrozooids, another type of polyp that digests the food with powerful enzymes. These venom filled tentacles also protects the blue bottle jellyfish from large predators. The toxins are strong enough to paralyze large fish, if not kill it, and enable a getaway.
More Info
Habitat : The Bluebottle lives in oceans.
Life cycle : Bluebottles are hermaphrodites, so each individual gonozooid consists of male and female parts. The fertilised egg develops into a planktonic larval form which produces the large Physalia colony by a sexual budding.
Diet : The Blue Bottle feeds on small fish and other small ocean creatures. They capture their prey with their tentacles, where a poison is released leaving their prey stunned. The tentacles attach extremely well to their prey. If a tentacle is put under a microscope it looks like a long string of barbed wire, which shows the ability of this jellyfish to kill its prey.
IT'S Sting
Introduction
When the blue bottles come in contact with humans, they react in exactly the same way as they would when faced with danger, and they sting us. Blue bottle jellyfish stings are known to be extremely painful. The sting can cause an extremely painful rash which doesn't subside for at least an hour after the sting. While the sting in itself does not cause any major effects in the human body, a sensitive individual who is prone to allergies can have an extreme reaction to the toxins in the blue bottle's venom. An allergic reaction can lead to fever, heart and lung failure and may even lead to death, even though it is extremely rare.
Blue bottle jellyfish is so-called in Australia and New Zealand where it is also commonly known as Blue Bubble Jellyfish. Elsewhere in the world, this creature is usually called the Man of War or Portuguese Man o' War, since it resembles a Portuguese battleship with a sail .
