Hard Tissue Tumors of Scleractinian Corals
1975The susceptibility of vertebrates to neoplasia is believed linked to the presence of an immunologic apparatus and a well-developed lymphoid system1. Recent observations on invertebrates have revealed the presence of primitive immunologic mechanisms, beginning with the coelenterates2.

Reassessing evolutionary relationships of scleractinian corals
Coral Reefs, 1996The widely accepted family tree of Scleractinia published by Wells, based on a combination of morphological coral taxonomy and the fossil record, has recently been revised by Veron. It is now possible to test the validity of some of the conclusions reached by these and other authors by the use of molecular techniques.

Sexual Reproduction of Scleractinian Corals
2010Sexual reproduction by scleractinian reef corals is important for maintaining coral populations and evolutionary processes. The ongoing global renaissance in coral reproduction research is providing a wealth of new information on this topic, and has almost doubled the global database on coral reproductive patterns during the past two decades ...

Skeletal Low-Magnesium Calcite in Living Scleractinian Corals
Science, 1975The skeletons of living specimens of the scleractinian coral Porites lobata have been found to contain up to 46 ± 5 percent low-magnesium calcite even though free of gross detrital inclusions and boring or encrusting organisms.

Immunological specificity and memory in a scleractinian coral
Nature, 1977Tissue transplantation immunity with a specific memory component is demonstrated in populations of Montipora. This highly discriminating immunoreactivity derives from extensive allogeneic polymorphism of histocompatibility (H) markers. An H system of immunorecognition is postulated to have originated in multicellular invertebrates probably beginning ...

A Cretaceous Scleractinian Coral with a Calcitic Skeleton
Science, 2007It has been generally thought that scleractinian corals form purely aragonitic skeletons. We show that a well-preserved fossil coral, Coelosmilia sp. from the Upper Cretaceous (about 70 million years ago), has preserved skeletal structural features identical to those observed in present-day scleractinians.

Biodiversity of Reef-Building, Scleractinian Corals
2019Zooxanthellate scleractinian corals are moderately well-known for shallow reef habitats, but not for mesophotic depths (>30 m) that are relatively difficult to access. Mesophotic habitats are light-limited, with different hydrodynamics and sedimentation processes, which result in growth forms that are often difficult to classify using traditional ...

Scleractinian Coral Species Survive and Recover from Decalcification
Science, 2007Anthropogenic-driven accumulation of carbon dioxide in the atmosphere and projected ocean acidification have raised concerns regarding the eventual impact on coral reefs. This study demonstrates that skeleton-producing corals grown in acidified experimental conditions are able to sustain basic life functions, including reproductive ability, in a sea ...

Patterns of Fluorescent Protein Expression in Scleractinian Corals
The Biological Bulletin, 2008Biofluorescence exists in only a few classes of organisms, with Anthozoa possessing the majority of species known to express fluorescent proteins. Most species within the Anthozoan subgroup Scleractinia (reef-building corals) not only express green fluorescent proteins, they also localize the proteins in distinct anatomical patterns.We examined the ...
