What does madrepore mean?
A madrepore is a stony coral belonging to the genus Madrepora, a group noted for reef-building colonies with branching, encrusting, and related forms. Each apparent “pore” on its shared skeleton is a corallite, a small skeletal cup in which an individual coral polyp lives. A colony therefore resembles a single organism to the casual observer but is actually composed of many genetically connected polyps that build the same structure. The word is chiefly used in marine biology, taxonomy, reef ecology, and the study of fossil corals, where finer identification may be important. Madrepora corals contribute to complex reef habitats by providing surfaces and shelter for other marine organisms. The term is more precise than the general word “coral” and should not be treated as interchangeable with it in scientific description. Its memorable name refers to the conspicuous openings from which the colony’s polyps emerge.
nounA stony coral of the genus Madrepora, characterized by colonies of small polyps that build a shared calcium-carbonate skeleton. The term may refer specifically to the branching, encrusting, or other growth forms found in this genus.
- A coral belonging to the genus Madrepora, especially a reef-building coral with a branching, encrusting, or related colony form.
"A delicate madrepore grew across the sunlit reef, its branching colony sheltering tiny polyps."
"Marine biologists identified a new madrepore growing on the outer edge of the reef."
"The skeleton of an ancient madrepore preserves the outlines of hundreds of individual corallites."
The plural is used when referring to multiple corals, colonies, or members of the genus.
"Several madrepores were recorded along the exposed reef slope."
The name means “mother of pores,” an apt description of a colony whose many small openings give rise to the living polyps.

Where does madrepore come from?
Madrepora is an 18th-century New Latin taxonomic name formed on Spanish madrepora. Its elements refer to the coral’s numerous pores: Spanish madre means “mother,” while the pore element continues Latin porus, from Greek poros, meaning “passage” or “pore.” The name was chosen for the small openings in the coral skeleton through which the polyps extend.
How madrepore is actually used
This is primarily a zoological and taxonomic term rather than a general synonym for every kind of coral. In technical usage, it identifies a member of the genus Madrepora.
