Jellyfish have an unexpected appearance until they become adults.
The ecology of jellyfish is interesting not only in the way of maintaining life. They change their appearance as many as four times before they become adults and float. Specifically, it gradually changes into jellyfish in the following order.
Pranula → polyps → Strovilla → Epira → Metefila (jellyfish)
Until it reaches the stage of ‘Efila’, just before the final form of jellyfish, it has a shape that you can’t expect to become a jellyfish.
The most strange thing is a stage called a sea anemone-like polyp, where several narrows called strovilla are attached, and then cracks to form the shape of a baby jellyfish called Efira.
The following video shows the split from Strovela to Epira.
In other words, the baby will be born gradually after it is divided into smaller pieces. Jellyfish has a large floating image, but it makes sense if you divide this much in an individual.
Note that at this stage, all jellyfish divided are so-called copies with the same properties, and there is no distinction between male and female. It’s a real shadow self-immolation.
Jellyfish melt in water when they die.
From the legs of the brain and heart to the shadow of childhood, it feels so amazing that I’m already full, but it’s not like this yet. They will continue to hold on to wonder until the very end of their lives.
Jellyfish become adults and are divided in gender, and when they mate, they die, and the body melts into the water and is completely destroyed! In fact, jellyfish consist of 97% of the body’s water, so when life is over, cells melt and all become water.
It’s fleeting… but an environmentally friendly death.
There is also a maniac called ‘Hong Jeo-mi’ who does not die when he becomes an adult but returns to the polyp state and regains life. The world is already over, isn’t it? You’re ignoring the rules, aren’t you?
Perhaps there are jellyfish that have been reviving for hundreds of millions of years and continue to survive.
Clean up
Jellyfish do not have brains because their movements are all caused by reflexes of nerves. In addition, seawater consumed instead of blood carries nutrients, and the heart’s role in releasing them to the whole body is the movement of them swimming itself.
A really interesting creature. The more I chase it, the more trivia it is. I just want to forget what the heart is like in an aquarium and just look at it as pretty…
