Jellyfish live in salt water. They have organs (and cell organelles) that pump the salt out of their bodies. The jellyfish body
is actually filled with fresh water. Animals like sea turtles and whales eat them even though there are few or no calories in a jellyfish. Explain why this happens
when whales eat jellyfish they wont really be getting because as it was said in the question the whales are basically eating water and not getting any real food.
