Rabbit Coral / Antler Coral (Note: This is actually a stony coral skeleton, frequently collected alongside shells)
Phylum: Cnidaria, Class: Anthozoa, Order: Scleractinia, Family: Pocilloporidae, Genus: Pocillopora, Species: Pocillopora verrucosa · Pocilloporidae (Stony Corals) · Other (Stony Coral Skeleton, dendritic/branching morphology)
Species
Pocillopora verrucosa or Stylophora pistillata (Branching/Stony Coral)
Shell Type
Other (Stony Coral Skeleton, dendritic/branching morphology)
Family
Pocilloporidae (Stony Corals)
Size
Approximately 10-12 inches in length and 6-8 inches in height, which is a moderate-to-large size for a decorative coral specimen.
Color & Pattern
Uniform bright chalky white due to bleaching of the organic tissue, revealing the calcium carbonate skeleton. Fine porous texture covers the entire dendritic structure with delicate verrucae (wart-like bumps).
Rarity
Uncommon in pristine natural states due to strict international protection, though older specimens are frequently found in vintage collections or curio shops.
Habitat
Warm, shallow marine waters, typically in tropical reef flats, reef slopes, and areas with strong wave action where high oxygen and nutrient flow occur.
Geographic Range
Indo-Pacific region, including the Red Sea, Indian Ocean, and across the tropical Pacific to the Hawaiian Islands.
Description
An exquisite branching stony coral skeleton forming a striking natural silhouette resembling a rabbit or fantastical creature. The structure is composed of dense calcium carbonate, featuring numerous delicate branches tipped with clustered corallites and rough, textured surfaces. Its complex dendritic pattern showcases the remarkable architecture of reef-building cnidarians.
Key Features
Branching dendritic skeletal growth, porous calcium carbonate matrix, distinct verrucae (small bumps) along the branches, and a pristine white bleached finish.
Collector Value
Moderate as a decorative specimen or natural history display piece. Modern commercial trade of raw coral is heavily regulated under CITES, making vintage specimens valuable for display.
Condition Notes
Good vintage condition. The calcium carbonate skeleton is largely intact with minimal tip breakage, completely sun-bleached to a uniform white, and mounted on a wire display stand.
Interesting Facts
Stony corals are colonial organisms made up of thousands of individual polyps that secrete calcium carbonate to build massive underwater reefs. Many species of branching corals grow very slowly, sometimes only a few centimeters per year.
Ecological Role
Living stony corals form the foundational framework of coral reef ecosystems, providing critical habitat, shelter, and feeding grounds for thousands of marine species, protecting coastlines from erosion.
Similar Species
Acropora cervicornis (Staghorn Coral) and Seriatopora hystrix (Birdnest Coral), distinguished by branch thickness and corallite arrangement.
Beach Finding Tips
In many modern jurisdictions, collecting beach-cast coral is illegal or strictly regulated to protect fragile marine ecosystems. Historically found washed ashore on tropical reef beaches after major storms.
