Jellyfish are some of the most beautiful and graceful creatures found in the oceans of the world. They are as diverse as they are beautiful and span the color spectrum from oranges, blues, whites, reds and yellows – and their sizes range from the microscopic level to colossal ones that measure several feet across and tentacles that can stretch over 100 feet long!
