Term for animals that live under water [closed]

What is the term for animals that live under water (not necessarily in an ocean)? Ideally this would include sharks, dolphins, crabs, seashells, salmons and pet fish. Here are some I can come up with, but none sound right:

  • Aquatic Animals
  • Ocean Creatures
  • Ocean Animals
  • Marine Lives
  • Marine Animals
  • Marine Creature

Solution 1:

Aquatic animal might fit best here. I just couldn't think of a better one.
