Description:
A colony of mountainous star coral (Montastrea faveolata) suffering a severe attack of the coral disease, white plague, which shows as a patch of white skeleton where coral polyps have been killed. This colony is 300-500 years old, and it lost about one-third of its living tissue in a week or so.

Description:
While protected areas canÕt protect corals from general threats like climate change and rising sea temperatures, they reduce the effects of anchor damage, vessel scraping, and loss of fish that that control algae. These two coralsÑstaghorn coral (Acropora cervicornis) and brain coral (Colpophyllia natans) benefit from protection in the Bonaire Marine Park, Netherlands Antilles.

Description:
Two colonies of brain coral (Diploria strigosa) on Curacao show the effects of a coral disease called white plague. The colony on the left has died completely, and the disease has spread to the colony on the right, where it shows as a stark white band encroaching on the still-living, colorful part of the colony.

Description:
A colony of mountainous star coral (Montastrea faveolata) with black band disease. This colony is about 300 years old and lost about one-third of its tissue in a few weeks. The ruler is 154 cm (six inches).

Description:
The coral disease called white plague spreads as a stark white band across a colony of elkhorn coral (Acropora palmata). The decline of this coral species in the Caribbean led a panel of scientists to conclude that it should be ranked critically endangered.

Description:
Close-up of a branch of staghorn coral (Acropora cervicornis). Once one of the important species that provided architecture of Caribbean coral reefs, this species was judged to be critically endangered by a panel of scientists.

Description:
A cluster of several coral species, including the lettuce coral (Agaricia lamarki), are affected by a severe case of the coral disease called white plague. Each colony has lost about half to three-quarters of its tissue, leaving the bare white skeleton. Spreading from species to species, the white plague is now the most virulent coral disease in the Caribbean, causing tissue loss on the order of 1-2 cm per day. Colonies that are several meters in height, and hundreds of years old are dying within a few weeks to a few months.

Description:
A healthy reef on Bonaire, Netherlands Antilles, retains the three-dimensional structure that was once typical of coral reefs across the Caribbean and that provided shelter to a vast diversity of Caribbean fishes and other species. The coral species that are dominant in this viewÑstaghorn coral (Acropora cervicornis) and elkhorn coral (Acropora palmata)Ñwere both found to be critically endangered by a recent scientific panel.

Description:
The macro-alga Dictyota pulchella growing on a reef in Bonaire, Netherlands Antilles. Algae are primary producers that support much of the diversity on Caribbean reefs, but when the ecological balance is tipped, they sometimes take over large areas, adding to the stress faced by corals.

Description:
The turtlegrass, Thalassia testudinum, once formed large meadows in shallow waters of the Caribbean where they provide food and cover for many marine animals. Although the individual species of seagrasses were ranked at low levels of threat, the seagrass ecosystem has been greatly reduced across the Caribbean.
