Where is the mouth situated on the head of the zebra shark, reflecting its feeding style?
Answer
Ventrally and subterminal, on the underside of the head, behind the snout tip.
The head morphology of the zebra shark is heavily influenced by its benthic, or bottom-dwelling, lifestyle, and this is most evident in the mouth's placement and structure. The mouth is located ventrally, meaning it is situated on the underside surface of the head. Furthermore, it is described as subterminal, meaning it is positioned slightly posterior to the very tip of the snout. This downward-facing placement is characteristic of sharks that employ suction feeding, enabling them to effectively vacuum food items, such as hard-shelled invertebrates like mollusks and crustaceans, directly from the ocean floor or crevices where they reside.
