Scombrops boops

It is found in the Indo-West Pacific–specifically the Japanese Archipelago–and marginally in the southeastern Atlantic. The southernmost detection of this species in the Indo-West Pacific range is Hong Kong, consisting of juveniles from the Japanese Archipelago that spawned and followed the current southward. It occurs off South Africa, Mozambique, and in the East and South China Sea. The geographical distribution of S. boops is dependent on their age and spawning habits.

The feeding habits for S. boops depend on its age class. Juveniles are relatively small and mostly eat copepods and decapod larvae until they reach 40 millimeters in length. As they grow to 40-50 millimeters long, they start to consume clupeoid larvae exclusively. When S. boops grow greater than 50 millimeters long, they start to consume young clupeoides such as herring and anchovy. S. boops with body length ranging from 50-70 millimeters feed the most intensely and usually on adult clupeoides. Larger members of the species, above 180 millimeters in total length, feed primarily on adult fishes in the Apogonidae family.
