Abstract Gastropods are extremely diverse taxa comprising nearly 60,000 species, of which, the giant African land snail, Achatina fulica is a well-known member. It is an invasive species, and it serves as vector and host for several free-living and parasitic nematodes. This makes studies on the diversity of nematodes isolated from gastropods be more emphasized. Studies have been conducted on other Caenorhabditis-gastropod associations such as in the model organism C. elegans, however, less attention is given to other Caenorhabditis species. Through morphological and morpho-taxometrical data, and analysis of the D2-D3 of 28S rDNA and 18S rDNA regions, nematodes found inside a dissected A. fulica cadaver from Kabacan, North Cotabato (7°6’3.076” N, 124°51’68.33” E) in Mindanao, Philippines were identified as Caenorhabditis brenneri. We herein report for the first time C. brenneri from A. fulica. Moreover, to our knowledge, this is also the first report of C. brenneri-gastropod association.
