Common Narwhal

The common narwhal is a species of narwhal native to warm to cool oceans around the world, except the Arctic and Antarctic oceans, where it is too cold for common narwhals to live in. It resembles a horned narwhal in appearance, other than it lacks a tusk that resembles a unicorn horn and is very adaptable in warmer waters around the world. It is about the size of a horned narwhal without its tusks. They mainly feed on jellyfishes, worms, crustaceans, cephalopods, and fish. They are immune to the effects of human activities, unlike most other species of cetaceans, so pollutions do not effect this whale species and this species can still thrive even in acidic oceans, much like jellyfishes. They also flourish very well in captivities unlike most other whale species, and there hasn't been a record of any kind of a common narwhal attacking and killing any sapient species/beings nor dylanuses, so this whale species make good and cheap animals in aquariums of all kinds and is legal to keep. It is also a very common aquarium pet in many of the modified pools made by sapient species/beings.
