Jellyfish are soft bodied, free-swimming aquatic animals with a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate to acquire propulsion and locomotion. The tentacles may be utilized to capture prey or defend against predators by emitting toxins in a painful sting.
Jellyfish are found in every ocean, from the surface to the deep sea.
While jellyfish stingsare painful, most are not emergencies. Expect pain, red marks, itching, numbness, or tingling with a typical sting. Jellyfish sting so that they can catch and eat other sea creatures. But that sting can be turned on people. Jellyfish can sting if they brush against you when you’re swimming in the ocean. You also can get stung if you step on a jellyfish, even a dead one.
The benefits of eating jellyfish are rather controversial. Some Asian research suggests that consuming jellyfish collagen, which is the main protein in jellyfish, canbenefit people suffering from rheumatoid arthritis. But no formal scientific conclusion has yet been made.
An ‘immortal’ jellyfish is swarming through the world’s oceans, according to scientists. The Turritopsis Nutricula is able to revert back to a juvenile form once it mates after becoming sexually mature. Marine biologists say the jellyfish numbers are rocketing because they need not die.
Jellyfish in captivity, when maintained properly, will live about one year from start to finish. That is their normal life expectancy. This being said, if you have a jelly that is 2” in diameter it is about 3 months old and you will have it to enjoy for about 9 more months.
Thanks to Jellyfish Art, a company now running a Kickstarter, your dream of owning a pet jellyfish could soon be a reality. This not your daddy’s fish tank. It’s a sleek and modern cylinder, with an ever-changing, multicolor LED light at the bottom and a gentle air pump, to allow the marine life to flourish.
