A very brief overview of their complicated life cycle is: a fertilized egg hatches and becomes a planula larva, this larva transforms into a polyp, the top of this polyp will bud off and become a baby jellyfish (an ephyra), and this ephyra eventually turns into an adult jellyfish (a medusa). Most people are only familiar with full-grown jellyfish—the eery, translucent, bell-like creatures that occasionally wash up on sandy beaches. Jellyfish also often practice cannibalism (where they eat other jellyfish). In the wild, they typically eat zooplankton, and as pets, they typically eat brine shrimp.

Since they rely on currents to travel if the food settles then the jellyfish cannot reach it. Other predators include tunas, sharks, swordfish, sea turtles and penguins. Once their prey is paralyzed or dead, they use their tentacles to move the food up to their mouths. The medusa stage is the adult reproductive stage, and therefore an adult jellyfish is called a medusa (plural medusae).
