What would be the physiological/anatomical adaptations of a 50 metre sea serpent?

In my last question, How large could my sea serpents be?, I asked what length would be a) possible and b) necessary for a whale-eating sea serpent. My sea serpent is a constricting predator* in a clade with Muraenidae.

The only answer I got there was nevertheless rewarding, and I recieved a great method of calculating the size of a constricting predator. So, here are the dimensions of the sea serpent:

• 50 metres long
• 1.25 metres wide
• 65,000 kg in weight

As it stands, this is my very rough diagram of sea serpent internal anatomy:

Note: they have reproductive organs and esophagi, I just forgot to put this in the diagram

So, what changes, if any, do I need to make to this creature's anatomy to sustain a 65,000 kg moray eel?

I know of some features that help sustain large animals, like large hearts, pressurizing muscles in the jugular vein, and bundles of nerve ganglia to serve as "second brains". Do I need any of these, or others?

*Some people, in my last question, believed that constriction is not a good method of predation in the ocean. I disagree, but what ever you think, please don't bother to bring it up in the comments. The entire dimensions of this animal have been based on it being a constrictor, so there's no point in re-raising the same statement now.
