Here's why:
* Porpoises are wild animals: Keeping porpoises in captivity is generally considered unethical and harmful to their well-being. They require vast open ocean environments to thrive.
* Terminology: The term "pond" is typically used for smaller bodies of water. A large saltwater enclosure for keeping marine animals would likely be called a "tank," "aquarium," "sea pen," or "marine sanctuary."
* Ethical Concerns: It's important to be aware of the ethical considerations surrounding keeping any wild animals in captivity. Porpoises are intelligent, social creatures that suffer in confined spaces.
