Facts
- 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)
