Large number of juvenile Bluestreak Fusilier fish shoaling in the ocean

New Born Swarms of The Ocean.

This video clip provides an undersea perspective of a massive shoal of juvenile Bluestreak Fusiliers, elegantly weaving through the waters of Mauritius. The young fish, with their slender bodies, display a dazzling blend of colors—from the soft yellow of their undersides to the subtle blue streaks that line their face. These colors seem to shimmer and change as the school moves in unison, reflecting the sunlight filtering down from above. The seabed in this shot is scattered with coral debris and intermittent patches of Leaf Scorpionfish, which serve as both a contrast to the dynamic swarm of fish and a reminder of the vibrant life that thrives in these waters.

The Bluestreak Fusilier, known scientifically as Pterocaesio tile, exhibits significant changes in size and coloration from juvenile to mature stages. Juveniles start with a more pronounced yellow coloration and blue streaks that run the length of their body, which serve as a form of camouflage in the open ocean. As they mature, their coloration shifts to a more uniform silvery-blue hue, and they can grow up to 40 cm in length. These schooling fish are a common sight on the reefs and open waters around Mauritius, often seen in large, tightly-packed groups that move together for protection and foraging.
