Wragon Hoakal Horror Aquatic universe

In the ocean, a great white frilled shark has both species' features and abilities while being able to be in hot and cold water and eats all things land and sea but makes an exception for its kind feasting in a fast frenzy. They can detect malignant liars especially humans that are exactly like that which anyone that is that kind of person at any time they enter the ocean a great white frilled shark will immediately head for them and  pursue them especially if they have any kind of cut when they get in and it's bleeding. They then eat that person. 

A submarine where the crew members all died and the submarine was destroyed had left behind a specter of its formal existence along with ghostly crew members on the USS Jeoeric happens. People who see this submarine when diving have experienced unease and when they look into the windows to see the ethereal crew members they have a heart attack and become a member of the unliving crewmates then it goes onto the next continental sea area. 

Over the build-up of decades, with things being dumped into the ocean a new human species emerged and thrive in the ocean exactly like us only they live in waters of the sea called homoaquasepian or Junaurac's which the two words are interchangeable. They have connections with world governments and deals with them but only top-level officials in those governments and they are much more advanced too. The jelly starfish has all features of both sea creatures in it's name and has more of both abilities. They can be in both seawater and freshwater with an effect of fourteen days of alcohol drinking and send people to the hospital and inject them with regenerative abilities leaving them with timelord abilities and pass it down the generations.
