My Creature is a Jellyfin. The genus is Chrysaora, genus of marine jellyfish of the class Scyphozoa (phylum Cnidaria). The Jellyfin is in the same species as Jellyfish, but possess its own unique qualities.
The Jellyfin originates in the deepest depths of Africa. Jellyfins lives in the Pelagic Zone of the ocean. They live so far off shore that they consider the Oceanic Zone their home. The Jellyfin does not photosynthesize because they find their food in the Disphotic Zone, or Twilight Zone, and the Mesopelagic Zone. In the Disphotic Zone there is no sunlight. Jellyfins are adapted to darkness, very cold temperature, and high pressure.
The Jellyfin has the ability to create its own bioluminescence. This factor is very helpful and vital to their survival because it is very dark in the Disphotic Zone. Without this ability, the Jellyfin would not have the capability to find and attack its prey. Jellyfins have a thick jelly-like coating which helps to keep them warm considering the temperature is so low where they live. Without it, they would not be able to withstand the low temperature and high pressure.
The Jellyfin has a very unique quality. They possess a fin that runs horizontal. This is a huge advantage because now instead of bobbing up and down like normal jellyfish, they have the ability to swim horizontally as well. The Jellyfin uses this in many ways. The fin allows them to swim much faster, either to escape from predators or to catch prey. Without this extra feature, the Jellyfin would have a hard time surviving in the Disphotic Zone considering the harsh competition.
The Jellyfin has a very effective tactic when catching prey. They use their bioluminescence to see what and if their is anything in front of them. They also use their tentacles to help them bob up and down so they don't seem as threatening. The prey won't even see them coming when they attack! Once they are in position, they use their fin to get to the prey quickly. Once they are there, they use their very large teeth to help them devour their prey.
The Jellyfin is about 4 inches across. They are very small, as are most organisms in the Disphotic Zone. They are black with red dots. The red specs come from their red, bioluminescent light that hangs over them. They have a black color to them because it is very dark where they live, and light does not penetrate throughout the water that deep. The Jellyfin will eat any small fish that live in the Disphotic Zone.
The Jellyfin uses their bioluminescent light to give them an image of what is around them. This is helpful when something is trying to attack them because they can see them coming. When a predator gets close enough, the Jellyfin will use their large teeth to try and intimidate them, while using there tentacles to sting the attacker. While they are stunned, the Jellyfin will use its fin to swim away, and escape fast.
The Jellyfin has some traits of a Plankton. They can float freely and drift with currents. Although they show traits of a Plankton, they are considered a Nekton. This is because they can maneuver throughout the water with ease. This is possible because their fin allows movement in any direction. Their shark-like fin allows them to move throughout any depths of the water, although they prefer the Disphotic Zone.
The Jellyfin makes its own oxygen. They produce and put it out throug their jelly coat. They release the oxygen into the water around them. After they release it, They absorb it back through their outer coat, then release carbon dioxide through their outer layer.
Jellyfin reproduce the same way normal Jellyfish do. They release their sperm or egg into the water around them, which attracts the opposite gender.
When you look at the Jellfin from this angle, you see their shark-like fin.
