First. What’s this? Is our spine also based on the design of a sea horse (beautiful creatures): 
The spinal cord has three parts: 7; 12; 5. (24)
The guitar has “24” frets.
I also have a hunch (back) that the spinal cord is connected to the jellyfish in a wicked evolutionary way. Sometimes, I get the impression that our spinal cord and brain are bathed in water because our body is simply a vessel to permeate the physical realm (our body is living in water still), where as our spinal cord and brain are the remnants of a jellyfish, as well as plant life that merged over time to create the human body, which is 90% fungi/plant.
Do I dare mathematically connect the jellyfish to our brain and spinal cord?
Jellyfish are cool. There is one, a Box Jellyfish, that has a more cube-shaped head with one fully-developed eye on each side of the cube and 20 other light-sensitive eyes on hits head (24 eyes total). Also has a more or less complete nervous system, apparently.
I wonder how you would connect the jellyfish to the spinal cord and the guitar? That would be fascinating to see.
You’ve got to be kidding me. The jellyfish also has “24” light-sensitive eyes?
And you “wonder how” we’re going to connect them?
We just did.
The guitar has “24” frets.
The spinal cord has “24” altogether separated in “3” parts.
Now you found out the box jellyfish has “24” light-sensitive eyes.
Either I’m super lucky the box jellyfish happened to have “24” eyes, or this brain of mine is not learning “knowledge” - it’s learning “super knowledge”.
