Global changes are one of the well-known shifts in species ranges in response to changing climate. Muricidae (murex) (Chicoreus ramosus) is one of the less well-known species in our locality. The early detection on the range in shifts of some seashell species and quick execution of culture and resource enhancement strategy are critical, so this study aims to document the sightings and morphometric relationships as the basis for a possible culture management program. The study uses a mixed-methods research design, particularly a sequential exploratory design. Results showed that there are a variety of murex species that are found on the island. The shell morphometrics relationship got this model of LW = 0.095 + 1.08 length, or weight =323.32 + 1.08 length, and LW = 0.195 + 2.478 width, or weight =887.06 + 2.478 width, respectively. Results suggest that there could be potential for reproductive biology and culture in captivity.
