Jellyfish and their relatives

Description

Medusozoans are a major group of gelatinous animals that many divers recognize as jellyfish—often drifting through the water column or hovering near currents. Depending on the species and location, you might see delicate, translucent bells, trailing tentacles, and sometimes swarms that glow or shimmer in sunlight as they move.
