All-Purpose Flour – This recipe turns out best with all-purpose flour. However, you can swap in a good gluten free flour blend ( like this ) if needed. Just be sure to stir the batter longer than normal to help give the cake proper structure, and let the batter sit for about 20 minutes before baking it if you opt to make a gluten free version. If you want to, you can frost the bottom part of the cake all the way up to the edge of the base of the pan so it looks like sand at the bottom of the sea, but you’ll still need to carve the cake smaller than the pan now, so there’s room for that frosting. Make any changes you want to your cake and then wrap it in acetate again, tape it with cling film, re-attach the springform pan and once the jelly is cool, pour it over the cake! Unlike many animals, jellyfish aren't in danger of becoming extinct - there are actually lots and lots in the oceans! Too many jellyfish can have significant impacts on humans, as well as other creatures in the ocean. While some jellyfish are safe to eat there are others that you must avoid at all costs! Some jellyfish can be extremely poisonous and dangerous for humans to be near. The most deadly jellyfish is the box jellyfish. Here are some box jellyfish facts that will amaze you:

If you aren’t happy with your cake after removing the acetate, pull the jelly parts away from the frosted cake and put them in the microwave at 50% power for 30 seconds at a time to melt the jelly again. So, what do jellyfish eat? Here are the main components of the average jellyfish diet. The Jellyfish Diet Plankton Finally, we’re going to create the jelly ocean!Cut a piece of acetate so it’s long enough to wrap around your cake, and at least as high as you want the cake to be. Because jellyfish don’t have gills, they absorb oxygen through their skin. Some jellyfish have light sensors called eye spots that can sense sunlight so they know which way is up. Some other jellyfish are bioluminescent, so they can produce light from their bodies. Scientists believe this to be a defence mechanism to protect them from prey. Moon jellyfish: these are the most common jellyfish that are found in the UK. They are typically the size of a plate, and have four distinctive circles that you can see through their bell. Below is a picture of a moon jellyfish.

Mix 5 Tbsp of gelatin and 1 cup of cold water together in a small bowl until combined. Set aside to let the gelatin absorb the water and bloom (this usually takes about 5 minutes). Oxygen in the water can simply filter through these cells and into the body of a jellyfish. Due to this, jellyfish don’t need to have blood pumping around their bodies like mammals and this means they have no reason to have a heart! If the frosting on the cake went all the way up to the acetate at the bottom of the cake, that frosting will be exposed when you peel off the acetate and the jelly ocean will start higher up on the cake. If any jelly seeped below when you want the ocean to start you can carefully peel off those thin patches of jelly. Place the cake in the fridge to chill while you work on the gelatin ocean. Leftover frosting can be left out overnight or refrigerated. Step 6: Adding the Gelatin Ocean

Second place goes to Nomura’s jellyfish which can grow from the size of a grain of rice to be bigger than a person in just 1 year! These jellyfish can have bells that are 2 metres across. These critters can be found in the Yellow Sea and the East China Sea. Did you know that some jellyfish have teeth? The beriod comb jellyfish has hundreds of tiny ‘teeth’ that are made from little hairs. However, these are more than enough to help these jellyfish eat their food! Jellies have the simplest-known nervous system among multicellular animals. Nerves in the jelly’s external layer form a nerve net. The nerves generate pulses that contract the jelly’s bell, allowing it to swim. The nerves also detect changes in water chemistry and can sense touch. Jellies in the class Cubozoa even have complex eyes and can respond by swimming toward or away from the light and dark they see. The jelly’s circulation system is made up of canals filled with fluid that transports food and distributes nutrients. DietPlace the cake on the base onto a piece of cling film or Saran Wrap and lift the plastic up to wrap it around the acetate. Secure it tightly with a few pieces of tape. This will stop the jelly leaking out of the bottom of the acetate. Unlike most jellyfish who float with the current, box jellyfish can control their movements and manoeuvre through the water. This helps them stay away from any predators. As mentioned above, there are around 2,000 known jellyfish species in the oceans, and there are thought to be way more than that. Learning about different species of jellyfish is a great way to put things into perspective and teach children how biodiverse the world is. Some jellyfish habitats are even situated in the UK! Here are some of the more common types of jellyfish that you may have heard of:
