Ctenella chagius
Ctenella chagius
Ctenella chagius (Chagos brain coral) may be the world’s most endangered coral lineage. A monotypic genus, it is a member of the Euphylliidae family and is found exclusively in the Chagos Archipelago Strict No-Take Marine Protected Area in the Central Indian Ocean. Its habitat has been historically protected from direct anthropogenic impacts such as overfishing and other destructive activities; however, reefs within the region have been subject to recent mass bleaching events with high subsequent mortality and loss of habitat. A relict population scattered widely throughout the Archipelago continues to survive.
