The Sea Spirit Civilization, being marine life, has a layer of fine scales on the surface of their skin.
Therefore, Sea Spirit People do not wear clothes, and there is no need for them to wear clothes in the sea. However, when the Sea Spirit People came to Earth, this caused some Earth People to talk behind their backs, considering the Sea Spirit Civilization to be a civilization with primitive thinking. Despite their highly advanced technology, their mentality was still considered backward and barbaric, not even knowing to wear clothes, lacking a sense of shame.
Of course, this wasn't a big issue.
Complaints aside, Earth Civilization would still tolerate and endure some of the biological habits of the Sea Spirit Civilization.
However, Earth Civilization never anticipated how vastly different the Sea Spirit Civilization's biological habits were from their own. It was one thing not to wear clothes, but the Sea Spirits could engage in reproduction at any time and place.
