‘The red paper lantern medusa has a transparent, bell-shaped hood measuring about 10 centimeters in diameter and 17 centimeters from top to bottom, with between 14 and 30 tentacles that extend up to 6 times the length of its body. Inside the transparent hood is a deep red colored mantle that can crumple up or expand like a paper lantern, hence the name. JAMSTEC researcher Dr. Dhugal Lindsay is credited with coming up with the name.
