Correct option is A
Correct Answer: (a) Scaridae
Explanation:
→ Scaridae (parrotfishes) commonly exhibit protogynous hermaphroditism, where individuals begin life as females and later transform into males.
→ This enables effective control of harems and increases reproductive success.
→ Sex change is often triggered by social dominance or removal of the terminal-phase male.
Information Booster:
→ Colouration changes accompany sex reversal in parrotfishes.
→ Protogyny is widespread among reef fishes to optimize mating systems.
→ Ensures stability of population structure in coral reef ecosystems.
Additional Information (Other Options):
(b) Moronidae – Bass fishes, not hermaphroditic.
(c) Bathysuridae – Deep-sea group; not known for protogyny.
(d) Clupeidae – Herrings; no hermaphroditism.
