Jellies are commonly found in the waters off California, Japan, and the East Coast of the United States in the Atlantic Ocean, Arctic Ocean, and Pacific Ocean. They prefer the tropics where the water is between 9 and 19 degrees Celsius, but they can be found as far north as 70 degrees latitude and as far south as 40 degrees. Usually, they are an inshore species meaning that they often dwell in places like estuaries and harbors.
