Do Jellyfish serve any useful purpose?

Question

They sting, they hurt, they kill fish, and sometimes people. Do they have ANY useful purpose in the ocean?

Answer 1

they're cool..
lol idk.
and they're pink! everyone loves pink!haha

Answer 2

Kinda silly question, everything has a purpose. I recently had to explain the purpose of a housefly to my five year old! So I am thinking that the population of whatever it is that they eat would take over the ocean if they didn't exist. I am sure that you will get a much more scientific answer here, but the theory is the same for any thing. We are all interconnected.

Answer 3

Jellyfish kill fish your right.... thats their main purpose just think if they didn't kill fish how much fish would be in the ocean... there would be two many fish, because fish create so many babies... the ocean would be over populated

Answer 4

Ten Reasons to Study Cosmic Dust Cosmic dust is the stuff of stars. Cosmic dust makes it into the news. Traces of cosmic dust tell us about our universe's evolutionary history. Cosmic dust might carry the precursors of life. Cosmic dust dynamics can tell us about the plasma and magnetic environments through which the dust particle is travelling. Cosmic dust has inspired artists, poets and songwriters. Cosmic dust can reach us from places outside of our solar system. Cosmic dust has inspired an group of enthusiastic dust scientists who use an armada of spacecraft and dust laboratories. Cosmic dust can tell us about the conditions out of which the particles were formed. We then learn about the particles' source: far-away in time and in space. Cosmic dust studies occur at a junction between electrodynamics, solid state physics, plasma physics, chemistry, fractal math, and almost every field of planetary science and astrophysics, such as celestial mechanics, geophysics, interstellar medium astrophysics, and planet formation. No results are intuitive at this junction, and the results are always interesting. AND Some dust is good . Most of the good dust is found in the sky. For example, the sunset. The dust in the sky gets in the way of the sun's rays. It deflects the rays in such a way that it makes lots of beautiful colors. Also, your mom probably told you about fairies and stuff like that when you were little. Well, there is fairy dust, too. This gives Peter Pan the power to fly. Even though that is fake, it is still good.

What do Mosquitos do? they bite you and give you viruses that KILL YOU! sheesh im like retards...maybe jellyfish like ... feed sharks...like the sharks are like MMMMM JELLYFISH LETS EAT THEM AND GET STUNG AND DIE! so i have no idea

Answer 7

no - none. I think God made a mistake making them. Perhaps he just had some goo left over from making everything else and figured throwing it in the ocean would be a good thing...

Answer 8

Do humans serve any useful purpose?

Answer 9

Why, of course, silly.

You can make yourself a peanut butter and jellyfish sandwich.
Doesn't that sound yummy?

Answer 10

They're a part of the food chain... they eat micro-organisms and smaller critters... larger critters eat them

Answer 11

Some turtles eat them.
