Abstract

Coral animals have tentacles in which there are Nematocysts in the ectoderm layer and zooxanthella in the endoderm layer, and these two components have a role as a defense and food source; this study was conducted to identify the components of Montipora danae coral tentacles. The research was conducted in Marak Island, West Sumatra, with a purposive sampling method based on the presence of M.danae. The coral samples were decalcified to separate the tissue from the skeleton. The results of this study indicate that M.danae consists of Nematocysts type sH (small Holotrich), MpM-I (Microbasic p-Mastighopore I), and H (Holotrich). Holotrich has the highest relative abundance of 74-91%, MpM-I has 3,92-20,63% and sH has 3-24%. Holotrich has larger morphometrics than sH and MpM-I, namely 72,76-82,35 μm capsule length and 19,55-24 μm capsule width. The zooxanthella density of M. danae was lower than that of normal corals at 624 cells/cm2

Abstract

This study aims to determine differences in zooxanthella density based on the life forms of coral Acropora Branching, Submassive Acropora, Branching, Foliose, Heliopora and comparing zooxanthella densities between the forms of coral form. This study was conducted in January-February 2020 on Marak Island, Nagari Sungai Pinang, West Sumatera Province. Zooxanthella density was calculated at the Marine Biology Laboratory, Department of Marine Sciences, University of Riau. The survey methode was used in this study, where the data collected was primary data. Coral Sampling was done by free collection using the SCUBA (Self Contained Underwater Breathing Apparatus). The result of study in the waters of Marak Island, West Sumatera on Acropora Branching corals were in the range of 0.004-0.13×106 cells/cm2. Acropora Submassive range of 2.95- 3.56×106 cells/cm2. Branching range of 2.41-2.59×106 cells/cm2. Foliose range of 0.44-1.09×106 cell/cm2. Heliopora range of 1.30-1.59×106 cell/cm2. The highest zooxanthella density was in Submassive Acropora and the lowest in Acropora Branching corals due to different forms of growth and temperature influences. Different forms of coral growth affect the zooxanthella density on a coral and the success of coral growth depends on the zooxanthella density and the size of the corallite of each coral life form.
