Spatial and temporal variations in strombus canarium (Gastropoda: Strombidae) abundance at Merambong Seagrass Bed, Malaysia

The abundance of marine benthic organisms often exhibits distinct distributional patterns, which is generally governed by many physical and biological factors specific to the habitat. In this study, the spatial and temporal variations in abundance of the dog conch, Strombus canarium Linnaeus 1758, a...
