Incidence of Stromboids Species Dispersal: The Case of Mantatao Island Calape, Bohol

Abstract

This study was conducted to determine the abundance of sea snails from family strombidae in Mantatao Island, Calape, Bohol. Quantitative research design was used in the study particularly the descriptive method using the transect line method with 2x2m per quadrant with a five (5) point scale in determining the abundance of stromboids species. There are nine (9) commonly stromboids species found in every quadrant in Mantatao Island. The species are spider Conch Shell Strombus erythrinus, Silver Conch Shell Strombus lentiginosus, Spotted Conch Shell Strombus maculatus, Variable Conch Shell Strombus variabilis, Rooster-tail Conch Strombus gallus, Little Bear Conch Strombus urceus, Scorpion Shell Lambis scorpius, Common Spider Conch Lambis lambis and the Millipede Spider Conch Lambis millepeda. Conch shell Stombus erythrinus got the highest numbers of individuals while Millipede spider conch Lambis millepeda, got the lowest. Results implied that distribution of stromboids species in the island showed significant indicator that the island has a diverse ecosystem.
