The sea slug is a small, translucent creature with a long, thin body and a wide, flat head. Its tentacles are long and thin, and its eyes are large and round. Its body is covered in small bumps and ridges, giving it a bumpy texture. The coral reef is teeming with life, with a variety of fish and other marine life swimming around it.
