An eternal autumn



Like trees with colorful leaves of change in autumn, soft corals can create colorful underwater vistas in tropical seas. But despite their beauty, soft corals may sometimes indicate a turbulent past in a reef ecosystem. Soft corals are successful colonizers and are often among the first species to appear on damaged reefs. Several areas in the Indo-Pacific have seen an increase in soft corals since a major coral bleaching event destroyed many of the hard corals that dominated shallow coral reefs. Similarly, they often dominate reefs that have been subjected to dynamite fishing in the past.

Manamaalaya



The blue ring angelfish is the most common angelfish in Sri Lanka. It is particularly common on the western and southern coast where it prefers shallow inshore reefs. Juveniles of this species can be found near estuaries and on silty coastal reefs while large adults are often found on rocky reefs and shipwrecks. In Sinhalese, this fish is sometimes called 'manamaalaya' or bridegroom on account of its vibrant colors.

Descendants of Nereus


"But Pontos, the great sea, was father of truthful Nereus who tells no lies, eldest of his sons. They call him the Old Gentleman because he is trustworthy, and gentle, and never forgetful of what is right, but the thoughts of his mind are mild and righteous." — Hesiod, Theogony 233

Sunset Waltz


Mandarinfish are small colorful reef fishes (often 3-5 cm in length) that are known for their elaborate courting behavior. At dusk, males and females begin an elaborate courting ritual before swimming together off the reef substrate in a final mating embrace.

Napantao


Colourful soft coral, sponges, gorgonians and pristine hard corals adorn the walls of Napantao in Sogod Bay, Philippines. Thousands of golden anthias and damselfish cloud the water along the reef edge and clownfish play hide and seek among their host anemones. Larger fish such as sweetlips, snappers and groupers can be found sheltering behind large corals and in small caves, and if you are lucky you may even see a whale shark swim past. Not surprising that this is considered by many as the best dive site in Southern Leyte.

Whale Sharks of Sogod Bay

From November to May each year, whale sharks gather for feeding in the sheltered, deep waters of Sogod Bay in Southern Leyte, Philippines. A well managed eco-tourism industry has been established by several dive operators together with the local community. Regulations including a ban on SCUBA diving and flash photography, a minimum distance from the sharks, and time limits have been enforced. Locals have been employed as spotters and guides, and a sanctuary fee charged from tourists supports the local village. A successful model that benefits the local community and the tourists, while minimizing the impact on the sharks ensuring that they return to Sogod Bay in the future.
