How do jellyfish know to eat if they have no brain?
They filter in plankton in the same way that they move around.
Essentially, we would presume that a jellyfish would not know or think about what it's doing. A jellyfish would go on its instincts. You have to remember that a jellyfish still has neurons, but it will not have a center of control of these neurons (which we call the brain). Thus, the jellyfish would not think to attack another fish and eat it, its neurons will simply react to the closeness of a fish and… Read More
Usually the jellyfish stings a person when they accidentally get too close to it. The jellyfish sees them as a threat and tries to defend itself. They got no brain, so they can't even think what they are doing. Their sting is to protect themselves, and to stun food so they can eat it. They have no brain, so don't know a human from a goldfish. Humans just accidentally set off the jellyfishes' instinct to… Read More

A jellyfish is made up of 95% of water. They can have long tentacles that can be as long as a telephone pole. A jellyfish has no brain,heart, blood,or bones.Jellyfish are not a fish, fish are vertabrates,and jellyfish are in vertabrates.I hope you enjoyed these facts! they are 95% water!!!!!!! i know that's hard to beleave but its true!!!!
They're not 'afraid' - as they lack the intelligence to know when they're in danger. Leatherbacks eat jellyfish as part of their natural diet.
Yes. Sometimes fish can eat a jellyfish for example: a sea turtle can eat a poisinus box jellyfish.
jellyfish do eat bacteria jellyfish eat other smaller things - a 5th grader wrote this caleb
Sleep, as humans know it, is a brain activity where certain functions decrease in activity. Jellyfish do not have a brain. This means that, technically, they do not sleep. However, they do have periods of resting where they either hang in the water without moving or lie on the bottom of the ocean without moving.jelly fish do not sleep. they have no eyes - they just float in the ocean actually their is one type… Read More
Jellyfish. They have 4 hearts and no brain.
== == Sea turtles eat Jellyfish.
jellyfish eat small fish and microplankton
no way they eat fish not stingy jellyfish
Yes, jellyfish are heterotrophs. Heterotrophs eat and are consumers. Jellyfish eat, and are consumers: therefore, they are heterotrophs.
Sea turtles eat jellyfish because jellyfish are their prey and a source of food.
I know they eat zooplankton which are microscopic orgainisms that live in water. I have caught several jellyfish and am feeding them by supplying them with fresh lake water. Freshwater jellyfish typically eat zoo plankton from the water column. Using their nemocysts, they sting prey in the water, stunning it and allowing for easy entry into the animal's body.
There are many species of jellyfish. Most of them eat plankton some though have been known to eat smaller jellyfish. None are known to eat damselfish.
No; only specific jellyfish are. Actually, quite a few people around the workd eat jellyfish. Although, I do not recommend getting a jellyfish and cooking it to eat without training and/or experience.
Your question is too broad to answer as there are many species of jellyfish. For instance on the island of Palau where the jellyfish in one lake actually do not eat (catch food) at all. Please ask you question again specifying which species of jellyfish you are wanting to know about.
Jellyfish do not have a brain, or centralized gathering of nerves. They do have a nervous system with which to help them maintain their sensory organs and respond to stimuli, however. Nope
jellyfish eat whatever gets caught in their tentacles
Yes, some types of turtle do eat jellyfish.
Yes. Sea turtles do eat jellyfish.
Yes Sea turtles eat Jellyfish.
Possible, but not likely. Jellyfish eat whatever they can catch in their tentacles, mainly smaller fishes, eggs and larvae of sea creatures and zooplankton. The larger species of jellyfish eat crustaceans and other jellyfish.
The Irukandji jellyfish eats small fish and shrimp. The jellyfish will also eat other jellyfish and any other marine animals that it can catch and kill.

They do not have anything that could be called a brain.
yes, a jellyfish absorbs and dissolves its food, so t can eat it, but it isn't reccomended that you give a jellyfish a sandwich
No, in some parts of Asia people eat jellyfish on a regular basis. So at least some jellyfish are not poisonous.
I do not know of a particular species called "sand jellyfish", but many of course end up in the sandy beaches. Be careful not to step on them! In general, jellyfish eat a number of different things, but their main source of food is plankton, which are tiny plants that float in the ocean. They also eat other food sources depending on the species but range from zooplankton to small fish.
All jellyfish, as far as I know, have nematocysts (stinging cells) on their tendrils. These release neurotoxins into the victim as they wrap the tendrils around it. These neurotoxins can cause intense pain and spinal/neural (brain/nerves) damage.
Actually, jellyfish eat whatever they can!
