Philippine Corals

by Francisco Nemenzo

Prof. Francisco Nemenzo

"Father of Philippine Coral Taxonomy"

A renowned academic and naturalist, he earned his BS and MS in Zoology at the University of thePhilippines in Diliman, Quezon City. He went on to teach at the same university, eventually holding the prestigious title of Professor Emeritus. In addition, he also earned an MA from the University ofMichigan, USA.


Prof. Nemenzo devoted his life to the study of Philippine corals. He was among the first to do so, as the only previous work dealing extensively on the subject had been conducted some 30 years prior, based exclusively on specimens deposited in museums in the United States.


Despite never pursuing a doctorate or donning a SCUBA tank, Nemenzo meticulously described andcatalogued over 375 species of corals, including 94 new species and five new varieties. His work waspublished in seven volumes of “Systematic Studies on Philippine Shallow-Water Scleractinians” andseveral standalone papers, a process which took over 20 years. Nemenzo insisted on publishing these in local scientific journals, primarily the Natural and Applied Sciences Bulletin, as he firmly believed that understanding and protecting the Philippines’ rich biological heritage should be primarily the responsibility of Filipinos, and thus his work must be accessible to them.


During his lifetime, Nemenzo was granted fellowships from the Guggenheim memorial Foundation, USnational museum (Smithsonian Institution, Washington), and the British Museum of Natural History(London), as well as memberships in numerous local and international learned societies. He isimmortalized in the coral genus Nemenzophyllia (Hodgson & Ross, 1982), which is named in his honor.


To date, Nemenzo’s works remain the most comprehensive record of Philippine corals, and a preciouslegacy to present and future Filipino scientists.

Nemenzo described over 375 species of corals from specimens collected mostly from Mindoro, Palawan,and Cebu. Of these, he proposed that 94 were new species and 5 were new varieties it is these whichwe refer to as “Nemenzo species.” Just over 40 of these species are considered valid, while the resthave been synonymized.


Given the extreme diversity of Philippine corals, of which there are an estimated 505 species 1 , and therelatively low circulation and poor print quality of Nemenzo’s original publications, it is worth revisitingthis esteemed taxonomist’s identifications for their potential significance in defining Philippine coraldiversity.


Nemenzo’s original specimens are scattered in four repositories across the country: the Marine ScienceInstitute and Institute of Biology at the University of the Philippines in Diliman, Quezon City, SillimanUniversity in Dumaguete, and the University of San Carlos in Cebu. This poses a considerable challengeto scientists seeking to validate Nemenzo’s work.


This website provides, for the first time, convenient public access to a large collection of high-qualityphotos of Nemenzo’s specimens. These are accompanied by Nemenzo’s own original descriptions and the taxonomic source and material for each, along with updated information on the taxonomic status ofeach Nemenzo species and the current physical location of each specimen.
