by puting it back out their mouths
Cnidarians release waste through their mouth since they have no anus.
Cnidarians, such as jellyfish and corals, excrete waste primarily through diffusion across their body surface. They do not have specialized excretory organs like kidneys. Waste products, such as ammonia, are released into the surrounding water through their skin and tentacles.
The waste products that leave through the skin are water, urea, ammonium and uric acid. Some sebum (oils) is also lost.
The waste products of combustion leave the internal combustion engine through the exhaust valve.
Nuclear waste products can leave isotopes that contaminate the environment and cause heath problems.
Cnidarians, such as jellyfish and corals, lack specialized excretory systems like kidneys. Instead, they expel waste products through their single opening that serves both as a mouth and an anus. Digested food is absorbed into their body, and undigested material, along with metabolic waste, is released back into the environment through this same opening. This process allows them to efficiently manage waste in their simple body structure.

Yes it does
The kidneys filter waste products from the blood to create urine, which is stored in the bladder until it is excreted from the body. The waste products are then expelled from the body through urination.
A coelenterates body is basically a jelly like bag. The waste products of a coelenterate is excreted through the anus of the body.
The rectum is the final part of the digestive tract, and is where faeces, the waste products of digestion, are stored until they are expelled from the body. All the waste will then leave by the anus.
Nuclear waste products can leave isotopes that contaminate the environment and cause heath problems.
