To capture prey.
Jellyfish can eat in shallow or deep water. They use their tentacles to capture their prey and pull the prey in to their mouths. The mouth of the jellyfish is located under the bell or head of the jellyfish. They are carnivores and eat animals such as shrimp, zooplankton, and small fish.
nematocyts :)
ALL spiders use venom to capture and digest their prey.
jellyfish and mosquitoes are two creatures that have nematocust a stinging cell used by animals hunting and stunning their prey
Nematocysts are specialized stinging cells found in the tentacles of cnidarians, such as jellyfish and sea anemones. They are used for defense and prey capture by injecting toxins into their target. When triggered, nematocysts release a coiled thread that can penetrate the skin of the prey or predator.
They both use there tentacles to capture there prey and the mouth is near the center of the body
The animal is a jellyfish. Jellyfish have umbrella-shaped bodies and possess specialized stinging cells called cnidocytes, which they use for prey capture and defense.
carnivores
The moon jellyfish has a feeding tentacle that hangs at each corner of its mouth. The tentacle has stinging cells that are used to capture small prey and drag it to its mouth.
Moon jellyfish are carnivores, feeding on small planktonic organisms such as fish eggs, larvae, and copepods. They use their tentacles to capture their prey and then move it to their mouth for digestion.
Jellyfish tentacles have a variety of jobs. Their main purpose is to capture food. Usually they trail behind the jelly to fish for prey. Once contacted, tentacles have specialized cells that sting, stick to, or entangle the prey to immobilize it. The tentacle then contracts and draws the prey towards the mouth of the jellyfish, where oral arms push the food into the oral cavity for consumption. Tentacles sometimes are also used to aid locomotion, grasp onto substrates, and ward off enemies.
