A jellyfish is made up of mostly of water. 95% of water to be exact.
They survive without blood, a spine, a heart or a brain. Instead they have a nerve 'net' which they use to detect danger, find food, etc.
I believe jellyfish can survive without a heart because it is supported by homeostasis and metabolism. Some animals don't need a heart.
Jelly fish dont have hearts because they dont need them they have no blood and no control over themselves
They live by relying on nerve cells. They use that information to help them move about their surroundings and they sense food or predators. Other sensing organs help them figure out if they are moving up or down, towards light or away from it.
Jellyfish nervous system is made up of two neural rings, an inner and an outer one, located in the margin of the umbrella.
According to Seven Pounds, YES, a heart can be used after someone has been stung to death by a jellyfish. Tim Thomas committed suicide in the movie in order to give his heart to a woman with a severe heart problem.
The brainstem has a part named the medulla oblongata, which controls the natural, life necessary functions, such as heart beat. This is commonly believed to be the only part of the brain that perople need to survive.
It attaches directly to the brain but not the heart
heart
The brain.
A jellyfish & a starfish A Jellyfish has no brain & no heart A starfish has no brain & no blood
jellyfish

Jellyfish are invertebrates, which means they do not have a backbone.
A jellyfish, a seasponge.
Yes. Yes it is.

Jellyfish are extremely simple animals. They do not even have blood, a heart, or even a brain.
Yes, that's right. A jellyfish is an invertebrate, which means that it doesn't have a backbone or spinal column. Jellyfish are pretty much a blob, and with no brain or spine, its a wonder how they survive!
Heart is more important than your brain. When you fall in love you give your heart and not the brain. There are more songs on heart than brain. When it comes to learning also, your teacher and parents advice you to learn by heart. Joke apart, both the organs are vital for you and such comparison can not be done. You can not survive with non functioning heart. You can survive with non functioning brain. There is no meaning to existence with non functioning brain.
This question is a joke.
No.
