Correct Answer: (a) Sagittal
Explanation:
→ The sagittal otoliths are the largest of the three otolith pairs (sagittae, lapilli, asterisci) in most teleost fishes.
→ They play a major role in sound detection, balance, and age estimation.
→ Their size and structure make them widely used in fisheries research.
Information Booster:
→ Otolith rings help determine fish age similar to tree rings.
→ Composition is mainly calcium carbonate (aragonite).
→ Species-specific shapes help in predator diet studies.
Additional Information (Other Options):
(b) Asteriscus – smallest, used in hearing.
(c) Lapillus – involved in balance.
