These multi-celled organisms, distinguished by long, tube-shaped growths, are found growing within the coral reef ecosystem of tropical seas. Special florescent pigments in their tissue give them unique shades that range from hues of yellow to purple and blue. They provide an ideal habitat for invertebrates, such as shrimp and brittle stars.

Callyspongia Vaginalis have evolved the ability to mate as either a female or a male, increasing their odds for success. Throughout their lifetime, they are capable of playing both the female and male role.
