Physical characteristics: Aglantha digitale (abbrviated as A. digitale) is a medusa with a cylindrical umbrella that is about three-eighths of an inch to 1.5 inches (10 to 40 millimeters) high. active during the day, 2. lasting for one day. Aglan­tha dig­i­tale, also known as the pink hel­met, is found in north­ern seas, and north­ern parts of the At­lantic and Pa­cific oceans. Aglantha digitale belongs to the Invertebrates group. The inside of its bell is lined with giant ring axons and circumferentially lined with myoepithelial cells. Its bell can be up to 4 centimetres across.
