The sea slug appears to be a goosefish, with its large, round body and long antennae. Its shell is a deep red color, and its fins are a lighter shade of red. The fish are a variety of colors, including yellow, orange, and blue. The plants in the background are lush and green, providing a vibrant contrast to the sea slug.
