Resembling delicate snow crystals, Marine-Crystal plankton float elegantly on the surface of the water. The plankton get their name from their distinctive snowflake shape. They grow in clusters of 35 and line up in very orderly formations. When stimulated, Marine-Crystal plankton spin and produce vibrant sounds. While the plankton do grow in size if they are repeatedly tapped, they gradually return to their original size over time. They are born in four polygonal shapes: triangle, square, pentagon and hexagon. The ends of the crystalline protrusions also take on the same shapes. The tone of the sound they make will change depending on the shape of the Marine-Crystal plankton's body.
