Nothing Sees Color Like the Mantis Shrimp

mantis shrimp's vision


Hello and welcome back to another geniune blog post. Today we are going to be talking about the mantis shrimp's vision and the ridiculous amount of photoreceptors it has.  
Most mammals have two types of photoreceptors which are cells located in your eyes that convert light into electrical signals which allow the brain to see certain colors. Mammals have three photoreceptors, reptiles have four photoreceptors and butterflies have six. But the mantis shrimp has twelve photoreceptors. more suprisingly, the mantis shrimp uses an amazing vision system. Though of course they wouldn't be able to tell the difference between light yellow to dark orange because of how many photoreceptors they have, but they can easily see basic colors. The interesting fact is, unlike humans which have to have the signals go to the brain, the mantis shrimp skips that step of their vision.




 

I personally felt pretty interested in that article. I learned what a photoreceptor is and how it affects an animal's vision. The mantis shrimp's vision is what amazed me the most and I think it's vision is what makes this amazing arthropod move away from predators more easily.

     Viruses: Illnesses You Do Not Want to Get


You guys ever heard of viruses? You guys think that they can get into your body and infect you just like bacteria but they don't. In fact, I'm gonna tell you guys about the information about the virus.


 First of all let me tell you what the virus is, viruses are biological agents that have a protein coat called a capsid. They are also smaller than a microrganism. How they affect the living organisms is that they can get into your skin then they can go deeper  and unlock it's way inside the cell and control the cell's mechanisms. Then the organisms get sick.

How viruses multiply is as I said using the cell's mechanisms. But that's not all, First they have to inject the strand of DNA and RNA to the organelles of the cell. Then they use the cell's organelles to replicate themselves.

Now let me explain what active and latent viruses are and how they are different. Active viruses are viruses that exist in an active state and cause disease when they get into your system and latent viruses exist in an inactive state once they get in to your body and don't cause disease, although, they will do years later. LINK


Some viral related illnesses besides the picture that I just posted above are AIDS, ear infections, and tonsillitis.LINK










Now let me explain to you guys who Edward Jenner is, Edward Jenner  is a physician who invented the very first vaccine in 1796 for smallpox, A disease that is still feared back then. Speaking of vaccines, vaccines are a weaked form of a virus that is used to make the immune system learn how to combat the virus kinda like a training session.























Fun Facts:

• The latin word virus means slimy liquid or poison
• Their are a million virus particles in a milliliter per seawater.
• Walter Reed discovered the first virus in 1901
• They are sometimes covered in a fatty coating

see ya guys later.
