This alien-looking creature is named for its translucent, moonlike bell. Instead of long trailing tentacles, the moon jelly has short tentacles that sweep food toward the mucous layer on the edge of the bell.
Plastic bags that end up in the ocean often look like moon jellies to animals that depend on these drifting creatures for food. Thousands of turtles and birds die each year after swallowing indigestible wads of plastic mistaken for jellies. You can help by eliminating single-use plastics in your daily routine!
