On the other fin, this article says of salmon spinal cords:
“When fresh, however, the spinal cord is all juices, marrow, and vitamins. It’s a flavourful jelly that remains intact when spiced and grilled.”

@Zaku Thanks. Sounds delicious. Please show the calories per 100 grams and nutritional info of any animals spinal cord?

There is a treatise by a Dr. Hannibal Lecter wiki info that discusses the nutritional value of various body parts.

Must have some value:

Swordfish Marrow & Wings

Ingredients: Korean chili wing sauce (1 part butter, 1 part Korean chili paste, 1 part seasoned sushi vinegar), Swordfish spine, citrus oil, sugar

In a medium saucepan over medium heat, whisk butter, chili paste, and sushi vinegar together until butter melts and sauce reaches a smooth consistency. Set aside.
Take swordfish spine and cut in half between vertebrae (there is a sweet spot dead center). Scoop jelly disc of marrow into a chilled shot glass rimmed with sugar. Add a dash of citrus oil. Save bones.
Fry bones for four to six minutes in deep fryer. If you don’t have a deep fryer, you can 1) pan fry over medium heat for ten to fifteen minutes, or 2) season vertebrae with salt and pepper, then bake at 425 degrees for 20 to 25 minutes.
Toss in chili and vinegar sauce. Garnish with cilantro or chopped celery leaves, and serve with the bone marrow shot.
