Creole wrasse – Clepticus parrae – are protogynous hermaphrodites; the largest fish in a group is a dominant breeding male, While smaller fish remain female. If the dominant male dies, the largest female changes sex.
Protogyny is the most common form of hermaphroditism in fish in nature. About 75% of the 500 known sequentially hermaphroditic fish species are protogynous.
Wrasses are always on the go during the day, but are the first to go to bed and the last to rise.
Clepticus: Greek, kleptikos = ‘related to thieves’
