Enypniastes is a genus of deep-sea sea cucumber. It is monotypic, being represented by the single species Enypniastes eximia. Due to its unique appearance, the species has been dubbed the headless chicken fish, headless chicken monster, and the Spanish dancer.[3][4] It is also known as the swimming sea cucumber, and some are called the pink see-through fantasia.[5]
