📖 Read the story
Sea slugs are small animals that live in the ocean. Many people call them the butterflies of the sea. This is because they have beautiful colors like red, blue, and yellow. Sea slugs do not have shells to protect them. This means they are different from most snails. How do they stay safe? Their bright colors are very important. The colors tell other fish that the slugs are dangerous to eat. This is called being toxic. Scientists wanted to know more about these colors. They found tiny parts under the slug’s skin. These parts use light to make bright patterns. It is like the slugs are wearing a colorful costume every day. This helps them stay alive in the big blue ocean. Nature is very clever! Would you like to see a bright purple sea slug one day?
