Some jellyfish are clear and can look like a plastic bag in the water. Others are in vibrant colors such as pink, yellow, blue, and purple, and often are luminescent.
The largest known species of jellyfish is the lion's mane jellyfish. The largest of its kind was found in 1870 in Massachusetts Bay with a recorded bell size of 2.3 metres (7 feet 7 inches) and a tentacle length of 37 metres (121 feet).
