Jellyfishes are evolved to live in saltwater, and their cells have mechanisms for absorbing water and excreting salts. However, in freshwater this ability works against them, causing them to swell up with water, and their cells burst.
Unless it is a saltwater or very brackish lake, the fish will die. Most saltwater fish cannot survive in fresh water and vice versa.
Aaron Fresh was born in the U.S. but then moved to Trinidad and then moved back the the U.S. (:
The cells gain water.
The water vacuole would burst
It would burst.
The density and pressure of saltwater is different from freshwater as is much of the bacterias and parasites. The acidity of the water is also of concern as the lower the PH the higher the acidity of the water. Saltwater being of a higher PH would not handle the lower PH of freshwater very well. Also if moving a freshwater fish to saltwater that fish will lose a great amount of water in it's body causing death and if the saltwater fish is moved to freshwater it will gain great amounts of water causing death.
The stomach pouch of a jellyfish serves as the primary site for digestion. Once a jellyfish captures its prey using its tentacles, the prey is moved into the stomach pouch where it is broken down by enzymes. The nutrients from the digested prey are then absorbed through the stomach lining and distributed throughout the jellyfish's body to support its metabolic functions.
so they cannot be spotted by any predators. they are also transparent, witch means the jellyfish is camouflaged. some aren't so transparent. the box jellyfish is quite colorful. some jellyfish are still because the current takes them with it such as the mediterranian jellyfish. the Enchanted Jellyfish is a very colorful creature. so most jellyfish are very active but some are lazy current users.
it will die
I'm pretty sure the cell may burst, think of it as a balloon, if you fill it up with too much of anything it will burst. There was a story a while back where a woman drank too much water and her cells began to burst and she passed away. It is called cytolosis, when cells burst due to osmotic pressure.
Since the man o' war has no means of propulsion, it is moved by a combination of winds, currents, and tides. Although it can be found anywhere in the open ocean
It is still open bt they moved it is on grant n osborn
