Survival of the Undetectable

This storyboard does not have a description.
Lets go before we get eaten by those sharks, don't they realize that we can see them?
Out of the group of sharks, these two sharks are the lightest. Sure, they aren’t visible to the fish below them, but due to their light grey tops, they are visible to the fish above them. Even though they have a better chance of eating the fish below them, so do the darker sharks. So over time, the competition for food does not go in the lighter sharks’ favor. Decreasing their chance of survival and reproduction.
I'm getting so hungry and they're is no food to eat! How will we survive?
Curse our genetics! We're clearly not suited for this environment and we won't be able to produce offspring. Then, there will be no trace of our light grey covered tops in future generations.
Over time these lighter sharks will find it harder and harder to survive which will result in them not being able to reproduce. The lighter sharks will die out and they won’t be able to pass on their genes to the future generation.
Goodbye world :(
In contrast to the lighter sharks, the darker colored sharks. Not only are they less visible to prey below them, but above them as well. This makes it easier for sharks to hunt for prey. SInce they have a vaster amount of food resources compared to the lighter sharks. As time progresses, the darker colored sharks are able to survive and pass down their genes to their offspring and future generations.
Bless our genetics! We're clearly suited for this environment and we'll be able to pass down our wonderful genes to the future generations.
Those fish never saw us coming.
You can clearly see how natural selection plays a huge role in this group of sharks. The Euphotic zone presented challenges to succeed in reproduction. Then, only the most “fittest” in this case, the darker colored sharks, are able to survive and reproduce. The lighter sharks however, weren’t able to cope with the challenges in the environment and as a result, they tend to leave less offspring compared to those who are more suited to thrive in the environment.
As you can see, the environment has now drastically changed in contrast to what the population was before. Over many generations, many of the lighter colored sharks died out before passing on their genes while the darker colored sharks we able to survive and reproduce at a greater rate. So over the years, more of the darker colored sharks were found in the population compared to the lighter sharked. The environment was able to choose the most desired/ advantageous traits for survival. This shows how natural selection has a huge role on how a population grows and thrives.
Natural selection not only occurs in the ocean, but all over different biomes. Whether it be savannas, rain forests, or deserts, natural selection is evident anywhere organisms live. Different environments challenge different populations on how to survive and reproduce. So, how do you think your environment challenges you to survive?
I can probably use my advantageous traits to survive here too right?
