Yellow boxfish with black spots swimming above a coral reef in Mauritius.

Yellow Boxfish Over the Reef

A bright yellow boxfish, likely a Yellow Boxfish, swims above the reef in Mauritius, standing out clearly with its vivid colour and neat black spots. Its box-shaped body gives it a rather unusual look compared with many other reef fish, which is exactly what makes it so memorable underwater. Around Mauritius, boxfish can sometimes be seen near coral and rocky reef areas, where they move quietly from one patch of seabed to another in search of small invertebrates and other food. Isn't it fascinating how such a small fish can look almost like a little painted ornament drifting through the reef?
