Scyphozoan Life Cycle
1. Planula : The free-swimming medusa is either female or male and produces eggs or sperm which combine to produce a larva, called a planula. The planula is planktonic and will float around until it finds a substrate to bind to.
2. Scyphistoma : Once the planula binds to a substrate it develops into a scyphistoma. Scyphistoma is a feeding polyp with protruding tentacles on top used to catch food particles.
3. Strobila : The polyp soon turns into a reproductive polyp with stacks of strobilae. The strobilae are immature medusa that are being asexually reproduced by the polyp.
4. Ephyra : When a strobila is mature it breaks away from the reproductive polyp as a planktonic ephyra.
5. Medusa : The ephyra matures into a full grown medusa.
