Moon jellyfish ! ! ! My Beloved ! ! !
Fun facts!!!
A group of sea jellies is called a Bloom !
The four hoof-shaped things you see at the top of a jelly are called 'gonads'!
The frilly tentacles you see in the middle are called 'oral arms' and is used to move the food it catches to its mouth!
Some species of jelly - such as the pink meanie - eat other jellies !

The jellyfish lifecycle is wild
Female and male jellyfish release sperm and eggs into the water and then hope that they meet each other (some do this every goddamn day). Fertilised eggs turn into tiny sea worms, that swim down to the sea floor and find a spot to hang out and grow.
For a while they look like little anemones (called polyps), but when they're ready the polyp starts growing tiny, baby jellyfish in layers, and then popping them off into the ocean to live happy, brainless lives.
You can see the babies forming in this image. The polyp (top middle) attaches and starts making new jellyfish in rings stacked on top of each other (top right, bottom left). Eventually when they're fully formed (bottom middle/right) they can be released into the open ocean.
