Jellyfish have a special organ called a siphon that they use to extract water from the ocean and breathe. They can also extract oxygen from the air, although this is not as common. Jellyfish are able to do this because they have a small disk on their bell that filters out particles. This disk also helps them to move in the water.
Jellyfish are able to breathe through their tentacles, a feature that has led to their nickname of “the sea’s air pump.” The tentacles are made up of many small gas-exchange cells that can rapidly transfer oxygen and carbon dioxide between the jellyfish and the surrounding water.
Jellyfish don’t have lungs. Instead, they have a special organ called a bell that they use to extract oxygen from the water. When jellyfish are disturbed, their bell contracts and this movement causes the bell to suck in water and air. This process allows jellyfish to survive in environments where other animals would die.
Jellyfish don’t have lungs. Instead, they use a sac-like organ called a bell to extract oxygen and other gases from the water.
Jellyfish are able to extract oxygen from water using a process known as diffusion. They have a network of small tentacles that they use to move food and oxygen into their cells.
