What does madreporite mean?
Madreporite is a specialist zoological and paleontological term for a coral belonging to the genus Madrepora. Members of this genus are stony corals, and many contribute to the elaborate structures commonly called reefs. Their hard skeletons consist of calcium carbonate and leave a distinctive porous or perforated pattern, often visible in fossils. In scientific writing, the term can distinguish these corals from other similarly shaped fossil organisms and may be used when discussing particular species, specimens, or assemblages. Madreporite is uncommon in everyday English and is more likely to appear in taxonomic descriptions, museum catalogues, geological research, or historical natural-science texts. It should not be confused with the genus name Madrepora itself: the latter names the broader biological group, while an individual member of that group is a madreporite. The word is also related to madreporic, an adjective describing corals of this kind or their characteristic skeletal structures.
nounA madreporite is a coral belonging to the genus Madrepora, a group of stony corals that includes many reef-building species. The term is used chiefly in zoology, taxonomy, and paleontology.
- A coral of the genus Madrepora.
"The fossilized madreporite preserves the branching skeletal structure of the original coral."
"Researchers identified several madreporites among the fossils recovered from the reef."
"A living madreporite extends its polyps from a hard, calcium-carbonate skeleton."
The regular plural is used when referring to multiple corals, fossil specimens, or members of the genus.
"Several madreporites were found near the edge of the submerged reef."
Its name joins “mother” to “pore,” a fitting clue to the perforated architecture of stony coral skeletons.

Where does madreporite come from?
The word comes through Medieval Latin and Italian forms from a compound based on Latin māter, meaning “mother,” and Greek poros, meaning “pore” or “opening.” These elements refer to the porous architecture characteristic of the coral skeleton. The same roots also lie behind the genus name Madrepora and related forms such as madreporic.
How madreporite is actually used
This is an uncommon, specialist term found in scientific, taxonomic, and paleontological writing. The genus name Madrepora is capitalized, while the common noun madreporite is not.
