What is ephyra larva and its functions?

Ephyra larva:

1. It is a larval form of jellyfish.
2. It is formed through the metamorphosis of a scyphistoma in the lifecycle of jellyfish.
3. In the last stage, the young medusae grow from the upper end and become an adult.

Function:

The ephyra permits the jellyfish to disperse to potentially appropriate environments and avoids all progeny from being concentrated in one area.
