Recent ‘bleaching’ and death of hermatypic (reef-building) corals has occurred extensively in Pacific Ocean waters of Panamá (Gulf of Chiriquí), near the Panamá-Costa Rica border. All hydrocorals (Millepora spp.) and scleractinian corals (5 genera) have been affected to some degree in the non-upwelling environment of Chiriquí. No other members of the macrobenthos showed signs of stress (lowered activities, morbidity) or reduced abundance. The affected area, including the mainland, nearshore and offshore islands, and adjacent waters, is about 10,000 km2. Further surveys in the Gulf of Chiriquí may reveal even more extensive mortality.This disturbance began in the dry season (January–April 1983), during a period of clear skies, low rainfall, and minimal river drainage. I first observed large, ‘bleached’ coral patches (up to 100 m2 in area) in mid-March, and observations by others indicate that coral ‘bleaching’ occurred in February and possibly as early as mid-January. Normal and ‘bleached’ corals observed in mid-March were ‘bleached’ and dead, respectively, by the end of April, suggesting that the disturbance is protracted. By the end of the dry season, 80 to 95% of all corals in the affected areas were severely ‘bleached’ or dead.

The massive ‘bleaching’ (loss of zooxanthellae) and death of reef corals that occurred in one area (Gulf of Chiriquí) on the Pacific side of Panamá and in the Galápagos Islands during February—April 1983 continued in these areas until September—October 1983, resulting in a catastrophic disturbance. Similar episodes have been reported subsequently throughout much of the tropical eastern Pacific region (Costa Rica, the entire Pacific coast of Panamá, and Colombia), in the central and western Pacific Ocean, in parts of the western Atlantic Ocean (Caribbean coasts of Costa Rica, Panamá, and Colombia), and in the Florida Keys and Bahama Islands.

Abundance And Diversity

The fossil record of shallow marine organisms in the Hawaiian Archipelago and Emperor seamount chain indicates that reef corals were absent during the first half of the Tertiary. Their appearance during the early Oligocene, 34 million years ago, is associated with several paleoceanographic events that appear to have combined to intensify gradually gyral surface currents in the north Pacific. This association suggests that corals were absent in the early Tertiary because of isolation of the Hawaiian Archipelago from the Indo-West Pacific (IWP), the center of reef coral abundance and diversity in the Pacific. Today, the number of species of reef corals in Hawaii is less than 10 percent of the number of species in the IWP. Since their initial colonization, reef corals have been present continuously in the Hawaiian Archipelago, although not without taxonomic change. Episodes of extinction and recolonization are the most likely cause of change in species composition. Recolonization from the IWP may also explain the low rate of endemism (about 20 percent) in the present-day coral fauna.

Argopecten purpuratus is a scallop distributed in the Pacific coast of Chile and Peru. Although this species is mass cultured in both countries there is no morphological description available of the development of this bivalve except for few characterizations of some larval stages described for culture purposes. In this work veliger larvae (app. 140 pm length) were examined by the scanning electron microscope (SEM) in order to study some aspects of the organogenesis of this species.Veliger larvae were obtained from hatchery cultures, relaxed with a solution of MgCl2 and killed by slow addition of 21 glutaraldehyde (GA) in seawater (SW). They were fixed in 2% GA in calcium free artificial SW (pH 8.3), rinsed 3 times in calcium free SW, and dehydrated in a graded ethanol series. The larvae were critical point dried and mounted on double scotch tape (DST). To permit internal view, some valves were removed by slightly pressing and lifting the tip of a cactus spine wrapped with DST, The samples were coated with 20 nm gold and examined with a JEOL JSM T-300 operated at 15 KV.
