Abstract:
Jellyfish are marine invertebrates that classified in the Phylum Cnidaria. This phylum
consists of the Class Scyphozoa, Cubozoa clan Hydrozoa. This research aimed to identify
the species of jellyfish that occur in the Kuala Terengganu coastal waters. Trawling
method was used in this research for five times starting from September 2006 - March
2007. There were three Orders occur in Kuala Terengganu coastal waters that identified
as jellyfish from Order Semaeostomeae, Rhizostomeae and Cubomedusae. Every Order
classified has different morphology. Distributions of jellyfish around the world's ocean
were sporadic and seemingly unpredictable in nature. Diversity of jellyfish caught is
analyzed by using Shannon-Weiner Index and species evenness. Relationship between
wet weight (w/w) and bell diameter (BD) were analyzed according to species caught. For
this relationship, it shows significant correlation for species studied in this research. The
highest diversity of jellyfish in this project is from the Order Semaeostomeae and
followed by species from Order Cubomedusae and Rhizostomeae. The diversity of
jellyfish was according to seasonal changes.
