Phylum: Cnidaria, Class: Anthozoa, Order: Scleractinia, Family: Acroporidae, Genus: Acropora, Species: A. cervicornis · Acroporidae (Staghorn coral family) · Coral Skeleton (Cnidarian skeleton)
Species
Acropora cervicornis
Shell Type
Coral Skeleton (Cnidarian skeleton)
Family
Acroporidae (Staghorn coral family)
Size
Approximately 8-10 inches in length, showing a robust branching colony structure. Wild colonies can grow up to several feet, but this is a medium-sized decorative fragment.
Color & Pattern
Bright chalky white, entirely sun-bleached and dried with no remaining living tissue or brown/tan pigmentation. The texture is porous and rough.
Rarity
Protected/Uncommon for collection due to conservation status, though previously common in historical shell shops.
Habitat
Shallow tropical and subtropical marine waters, typically found in reef flats and fore-reef environments down to about 50 meters deep.
Geographic Range
Western Atlantic Ocean, the Caribbean Sea, the Gulf of Mexico, and extending south to the coast of Venezuela.
Description
An intricate, highly branched stony coral skeleton featuring cylindrical, tapering branches that resemble the antlers of a stag. The surface is heavily calcified with numerous tiny corallites, creating a delicate yet sturdy arborescent framework.
Key Features
Cylindrical, branching columns tapering to pointed tips; distinct radial corallites along the branches; lack of heavy basal encrustation in this fragment.
Collector Value
Historically popular in coastal decor and shell collections, but modern acquisition is heavily restricted due to conservation laws protecting the species under the Endangered Species Act.
Condition Notes
Good decorative condition. Entirely bleached white with intact branch tips, minor abrasion at the base, graded as Fine for display purposes.
Interesting Facts
Staghorn coral is one of the most important reef-building corals in the Caribbean, providing critical habitat for numerous reef fish and invertebrates. It reproduces primarily through fragmentation, where broken branches take root and grow into new colonies.
Ecological Role
Serves as a primary architectural foundation for coral reefs, offering shelter and nursery grounds for marine biodiversity. Currently listed as Critically Endangered due to climate change, coral bleaching, and disease.
Similar Species
Elkhorn coral (Acropora palmata), which features flattened, blade-like branches rather than cylindrical ones.
Beach Finding Tips
Finding intact specimens washed ashore is rare today and often illegal in protected marine zones. Most specimens found in collections are legacy pieces from older private collections.
