Freshwater jellyfish is not a true jellyfish as are some of its marine relatives. Freshwater jellyfish differ slightly from the true marine jellyfish. Craspedacusta sowerbii (kras-ped-uh-kus-tuh) is the scientific name of this freshwater jellyfish.
One obvious difference is that unlike marine jellyfish, the freshwater variety has a structure called a velum on the ventral surface. This thin, shelf-like membranous structure extends inward from the circular edge (ring canal) of the bell. The manubrium, which ends in a mouth, extends down through a hole in the velum. The velum helps set these apart from the true jellyfish. However, because it looks like a jellyfish, we call it a jellyfish!
They are most often found in calm, freshwater lakes, reservoirs, man-made impoundments, and water-filled gravel pits or quarries. They can also be found in recreational fishing and boating areas. They have been seen in large river systems such as the Allegheny River, the Ohio River, and the Tennessee River. The jellyfish prefer standing water rather than currents. So, they generally are not seen in fast flowing streams or rivers.
They eat tiny, microscopic animals called zooplankton that are found throughout the water.
Can they sting? It depends. Like true jellyfish, they do have stinging cells (cnidocytes). This mechanism is designed for feeding, as the cnidocytes are utilized to paralyze macroinvertebrates and even small fish. However, we have no hard evidence that these organisms can penetrate human skin (though some have claimed otherwise).
On average, your heart beats 100,000 times a day. One day, one of those heartbeats will be your last. Then what?
The answer is found in Jesus Christ who said "I am come that they might have life, and that they might have it more abundantly." John 10:10 ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Very cool. I've only seen them once and it was at Fannin Lake about 20 years ago. Never knew of them until I saw them that one time.
