Abstract

Bucas Grande Island has rich marine biodiversity; however, little is known of these resources in scientific reports. Hence, a preliminary observation on the abundance and diversity of Conidae and Cypraeidae was carried out in the coastal shores of Bucas Grande Island, Surigao del Norte, Philippines. This study was conducted in the four sampling stations, viz., Socorro (Lungsod), Puyangi, Mabua, and Dapia. Sampling was done in May 2014 during low tide with plots of 20 × 20m laid on the intertidal flats for species acquisition. Beach combing and systematic snorkel surveys were done in the plots. All species under Conidae and Cypraeidae observed in the sampling plots were counted. Twelve (12) species were documented with 468 individuals: six for Conidae (Conus coronatus, C. ebraeus, C. magus, C. marmoreus, C. miles and C. vexillum) as well as for Cypraeidae (Cypraea annulus, C. arabica, C. argus, C. eglantina, C. isabella and C. vitellus). Abundance value of Conidae was greater (70%) tha

Conclusion

A total of 12 species (six species of Conidae and six species of Cypraeidae) were collected with 468 individuals. Gastropod abundance was highest in Socorro (Lungsod) with 43.20%. The Conidae (70%) was the most abundant family with 326 individuals, while Cypraeidae (30%) with 142 individuals. Among these species, C. ebraeus (25.85%) had the highest abundance in Conidae, while C. annulus (26.50%) in Cypraeidae. This paper bears significance, since it will be an added literature on gastropod species in poorly studied area in Bucas Grande Island.
