A survey on the diversity of marine macrogastropoda
in Pulau Songsong, Pulau Bidan and Pulau Telor on the
Northern Straits of Malacca was conducted. Specimens
were collected on rocky shores following NaGISA protocol
and the number of marine macrogastropod were recorded.
Distances and the number of the same species were
converted into Relative Abundance unit (individuals per
100 m2
). A total of 15 species of marine macrogastropoda
were found from seven families namely Neritidae,
Trochidae, Ceriitidae, Littorinidae, Turbinidae, Muricidae
and Potamididae. Seven macrogastropoda species were
newly recorded from these three islands. Morula marginatra
was the most dominant species and Pulau Songsong had
the highest genera and species diversity among the three
islands. (Copied from article).
