It sounds like you are describing a squid.
A coelenterate is an invertebrate aquatic animal such as coral, jellyfish, and sea anemones. Their bodies are distinguished by either tube or cup shape or an open ring with tentacles.

No, they are carnivorous. Some species (such as the upside down jellyfish, Cassiopeia xamachana) form a symbiotic relationship with algae (zooxanthellae) and are nourished by sugars derived from algal photosynthesis. But since they also feed on animal organisms, and sugar is neither animal nor vegetable, jellyfish are considered to be strictly carnivorous.
As in most animals, Jellyfish have stingers as a forn of self defense. If an Animal attempts to attack it, it will get a nasty sting, sometimes, even a deadly one. Due to this feature, jellyfish survive better than if they didn't have stingers. This said, some species of Jellyfish don't have stingers and are harmless.
An actinosome is the body of a coelenterate, a simple aquatic animal bearing tentacles, such as jellyfish and anemones.
try jellyfish, blue-ringed octopus, man-o-war, etc.
Jellyfish will prey on other jellyfish, shrimp, fish, and fish eggs. They will eat animal that drifts in to their tentacles.
Not exactly hollow. It's basically a mouth leading straight to its stomach. The tentacles sting the prey, and pass it to the mouth.
Jellyfish, They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for, locomotion while stinging tentacles can be used to capture prey.
Box jellyfish are carnivores that eat shrimp, fish, crustaceans, worms, other species of jellyfish and other small animal prey.
The lion's mane jellyfish, Cyanea capillata, was long-cited as the largest jellyfish, and arguably the longest animal in the world, with fine, thread-like tentacles that may extend up to 36.5 meters (120 ft) long.
A coelenterate is an invertebrate aquatic animal such as coral, jellyfish, and sea anemones. Their bodies are distinguished by either tube or cup shape or an open ring with tentacles.
Animals with tentacles include squid, octopuses, and jellyfish. Cuttlefish and Portuguese Man of War also have tentacles. Many people think starfish have tentacles, but these are actually true arms and legs.
The animal that has the same adaptations as a box jellyfish is a string jellyfish
The lion's mane jellyfish, Cyanea capillata, was long-cited as the largest jellyfish, and arguably the longest animal in the world, with fine, thread-like tentacles that may extend up to 36.5 metres (120 ft) long (though most are nowhere near that large).
Anemone.Please note that this is a riddle, not a biology question.An anemone is NOT a flower and it is NOT a plant. An anemone is an animal, and it closely related to jellyfish. (Imagine a jellyfish turned upside down: they both have spiral symmetry, stinging tentacles, and a "mouth" (sac gut) in the center). Search for "Cnidarians" to learn more about this group of animals.
