The Parrotfish's Sleeping Place
Before sleeping, parrotfish secrete a thin layer of mucus and wrap it around their bodies, like a transparent cocoon. This cocoon masks the fish's scent, making it difficult for nocturnal predators that rely on smell to detect it. Scientifically, this covering reduces the chances of attack and allows the fish to sleep safely on coral reefs, visible to the eye but protected from danger.
An innate intelligence created by God.
And proof that even the most beautiful creatures of the sea know how to protect themselves when darkness falls in the depths of the ocean.
