Do jellyfish go through metamorphosis?
Jellyfishes go through 2 stages. The polyp stage, then
the medusae stage. When a jellyfish is a fertilized egg, it
is called planula. When the planula is released from the pouches of
the jellyfish's tentacles, it will swim to the bottom of the ocean,
attach itself, and start growing. This is known as the polyp stage.
Then it will start "budding" and separate. The separated part would
then grow into a jellyfish, which is known as the medusae
