What does jellyfish use to get food?

Answer 1

Jellyfish have cells called cnidocytes, which contain nematocysts, and located on their tentacles, mainly. Whenever a prey comes in contact with cnidocilia (structures of the cnidocytes), hundreds to thousands of cnidae (filaments of the nematocysts) are ejected into the prey 's direction; nematocysts' cnidae inoculate a poisonous or allergenic mixture into the prey 's body; the prey , if live, die by osmotic shock, paralysis or anaphylactic shock and is then brought to the mouth with tentacles or with oral arms. Jellyfish of the Order Rhizostomeae have no tentacles, instead they have cnidocytes on the manubrium (oral arms).
Since jellyfish do not have eyes, they have to hunt passively. This means they just wave around their tentacles and hope for something to brush against its tentacles. When something does come in contact with its tentacles, it will fire out nematocysts and inject the prey with toxin and hope to have paralyzed or killed the prey.

Answer 2

Jellyfish are predators. Their stinging tentacles are not only to protect themselves but also to sting their prey. Depending on the size of the jellyfish, their prey can be microscopic or small-to-medium-sized fish. Once prey is caught, stung, and trapped in the tentacles, the jellyfish brings the prey back into it's mouth, which is underneath the round part of the jellyfish.

Answer 3

When it comes to hunting/gathering food, Jellyfish can basically be separated into two groups:

1. The first kind can only float along with the current of the ocean, with its sticky tentacles outstretched to catch possible sources of food. These jellyfish are passive hunters. Their diet will mostly consist of captured crustaceans, zooplankton, and eggs and larvae of other ocean creatures. These jellies usually have sticky tentacles and will wait for some food to get trapped in their tentacles
2. The second kind of jellyfish is more able to chase/swim after prey and hunt for their food. They have the ability to sting and stun their prey with their venomous tentacles. Their diet is mainly made up of small fish, and crustaceans, as well as other jellyfish. They can eat jellyfish that are even the same size as themselves.

Answer 4

They dont catch it.

Jellyfish have long tentacle like strands that hang down from their main body. These give out an electric pulse when something swims into them, which kills them. The jellyfish then digests its food.

Answer 5

They stun their prey with the tentacles and then eat it through their mouth on the underside of their body.

Answer 6

Jellyfish get their food by sting their prey to death and than moving it to their ''mouth'' on the lower part of their body. They then digest the prey.

Answer 7

Jelly fish possess stinging cells on tentacles which inject poison in body of prey to immobilize it . Tentacles grasp prey and engulf it .

Answer 8

They use their big fat cocks

Answer 9

the sting them
