These jellyfish are different in shape because of a deep groove running around the bottom of the umbrella, giving them the appearance of a crown.
Jellyfish are 95% water.
They have no heart, brain, blood, or gills. The body of the Jellyfish is called a bell. They do have a mouth, tentacles and arms around their mouth. They use their arms around their mouth to help sense and find food that ends up inside their mouth.
