Yellowback Fusilier
Caesio teres
Sighting evidence at Irabu Blue Cave, Miyako Islands
Dense schools of yellowback fusiliers orbit the cave entrance and reef slope in coordinated formations, feeding on zooplankton in the current while maintaining proximity to the reef for refuge. Their flashing silver and yellow colouring scatters the blue light from the cave entrance into a constantly moving mosaic. The school structure tightens dramatically when a trevally patrol approaches from the open water.
