The Brothers are a pair of tiny islands. Actually they are the exposed tips of two massive reef pillars that rise from the abyssal depths. They are the only significant reefs in the area, and as such act as a magnet for any pelagic and reef fishes. Washed as Theyare by the full force of open-sea currents, they support an incredible dense and diverse coral population, with almost overwhelmingly profuse soft coral growth on all sides.

Big Brother, the larger of the two, lies about 1km (0.6 miles) north of its sibling. It is an oblong landmass some 400m (1312ft) long, easily identified by its Victorian stone lighthouse, a legacy of British rule. A narrow reef table round the island's shore gives way almost immediately to a sheer vertical wall, dropping well past the limits of sport diving. Absolutely fantastic coral growth begins at the surface and continues unabated into the depths. Gorgonians, sea whips, antipatharians and, above all, a wealth of soft corals of every conceivable species flourish in the big currents. The stony corals are also well represented. The fish life here is more than impressive, ranging from the tiniest anthias in the shallows to the most impressive sharks in the depths offshore.This unique card provides detailed depiction of the Reef. Each waterproof card is printed on both sides, made of durable PVC plastic and is designed to be taken on the dive. They are also 3-hole punched to fit in standard log books.
