When the female is ready she will lay her eggs on top of coral or on part of a rock, usually near her food source. After copulation, it may take moments or days before the Spanish dancer is ready to lay her eggs. Spanish dancers are hermaphrodite organisms. The Hexabranchus sanguineus have a unique reproductive trait about them. SEA ROSE SEYCHELLES ( Spanish Dancer eggs) Male gametes are exchanged through a duct and fertilisation is internal. In case of threat, some produce a toxin and have no known predators, while others can escape the danger by swimming by undulation. When disturbed, some species will retract their gill plates. ![]() They do not have gill plumes but have gill flaps distributed in the cavity between the foot and the mantle. □ No marine organisms are known to prey on this species □.
