Why Do Comb Jelly Exist

The discovery of the Comb jelly which was the first animal fossil was a shocking and unexpected event to most scientists in the world. Scientists had a specific view about evolution. They thought that organisms evolve from a simple state to a more complex state. But that was not the case for the comb jelly which unlike what scientist thought was a very complex specie. It was so complex that it had a nervous system and tissues. But that was not the only misconception that they had to face. Another problem was that scientist believed for so long that the sponge was the first animal fossil, but this discovery has changed the order of species in the tree of life. 
They could not find the date of when Comb jellies have first existed. But if there existence predates the existence of
Moving on to This first animal fossil feeding regiment and habitat. Ctenophores are considered as a carnivorous specie. They consume a variety of planktonic organisms like fish larvae. The amount of food they eat is extremely large and the only way they can do so is by progressively pumping water inside their body cavities. Comb jellies can live in a variety of locations. Some live near the shores other live in deep water, but what ever part of the ocean they are found in the majority of the time the water is warm. They basically prefer a warm environment. 
 When it comes to adaptation this fascinating creature protects itself by producing when touched a colorful light that will scare away their predators, or attract larger predators that can now attack the predator of the comb jelly. But most of the comb jelly’s initial color when untouched is transparent which makes it easier for them to hide from their predators. It is a sort of camouflage.
 Furthermore comb jellies are considered as hermaphroditic which means that they have both the female and male reproductive system. They release on a daily basis an egg and a sperm in the water in hopes that it will
