Indian Threadfin Bream

Dense schools of threadfin bream hover above the reef in a shimmering curtain that catches the Gulf's clear winter sunlight, their pink and yellow flanks catching the ambient light in wide-angle shots. They are important mid-trophic prey species that connect the reef's smaller invertebrate community to the large predators — trevally, mackerel, and grouper — that patrol the reef edge. Their abundance on the Pearl Trail Reefs reflects low trawling pressure in the UNESCO-protected zone, providing a rare benchmark for what historically productive Arabian Gulf reef communities looked like.
