DIANDRY
diandry: translation
possessing two different types of males, a large, brightly-coloured and aggressive terminal phase (TP) and a smaller, drab and relatively non-aggressive initial phase (IP), e.g. in Thalassoma lunare (Labridae). The TP has priority access to food and spawning females. On the death or removal of a TP, the first-ranking IP becomes the next TP (after first checking the reef thoroughly to make sure the TP is gone). The two pathways of diandry are adult sex change as in monandry and also by direct male development from the juvenile phase with no adult sex change
