  • protandrous hermaphroditic; first male, then female (ref: Wiki)
  • most females spawn twice per year (ref: Wiki)
  • planktontic as larva, settle in stacks (ref: Wiki)
  • If a juvenile settles on an established stack it develops and may remain as a male for an extended period (up to 6 years), apparently maintained by pheromones released by females lower in the stack (ref: FretGrah1981)
