“…The clustered distribution of H. atra is believed to be a result of varying resource availability in different areas, allowing the species to select the most suitable location. This is supported by [23], which suggests that specific factors lead to the clustering of sea cucumbers in areas that provide favorable conditions for their survival. The sea cucumber species H. atra was found in almost all study areas, including seagrasses, macroalgae, open areas, and coral reefs.…”

Baluran National Park (BNP) is a natural resource conservation area known for its diverse land and water ecosystems. The intertidal ecosystem of Bilik Coast is home to sea cucumbers (Holothuria atra), which have both ecological and economic value. It is important to note that H. atra is a protected species in the BNP conservation area. Therefore, studying the distribution pattern of H. atra in the intertidal ecosystem of Pesisir Bilik is crucial. This study aims to determine the type of distribution pattern of H. atra and describe its spatial distribution. Purposive sampling was conducted at maximum low tide, and biotic data were collected using the Global Positioning System (GPS) to obtain coordinates. Biotic data were measured at 9 points as a representative area. The type of distribution pattern of H. atra was analyzed using the Nearest Neighbor Index using ArcGIS 10.7 which shows the type of distribution pattern and describes its spatial distribution. The research results showed that the distribution pattern of H. atra was categorized as clustered based on the result of R (ratio) < 1 (0.458). H. atra species were distributed in seagrass communities, macroalgae communities, open areas, and coral reef communities.

“…Madduppa et al (2021) noted that more than half of environmental DNA reads for invertebrate species from Indonesian coral reefs remain unidentified. Furthermore, many studies have focused on specific locations, primarily in eastern Indonesia, and/or specific taxa (Oedjoe and Eoh, 2015;Situmeang et al, 2017;Anzani et al, 2019;Alwi et al, 2020;Papu et al, 2020;Pratiwi and Elfidasari, 2020). Palomares et al (2007) reviewed the historical ecology of the Raja Ampat Archipelago, including the documented number of invertebrate species.…”

Macrozoobenthos communities play significant ecological roles in coral reef ecosystems. However, they are frequently overlooked due to their cryptic appearance, and their diversity remains undiscovered, particularly in Indonesia. This comprehensive review of publications on the macrozoobenthos in the coral reef ecosystems of Java - the most populated island in Indonesia, was conducted to compile a species list and gain an overview of its community composition. We also assessed the existence of species that are frequently reported, endemic, protected, and threatened. Data analysis was performed with data from 53 publications appearing from the 1980s to 2022. In total, 482 species belonging to 4 phyla and 9 classes have been recorded. Mollusca is the most speciose phylum (n = 321), followed by Echinodermata (n = 106), Arthropoda (n = 49), and Platyhelminthes (n = 6). Generally, the northern part of Java is well studied and has larger numbers of recorded phyla and species. The highest species number (n = 266) has been recorded off the northern coast of West Java, while there are around 25–99 species in other regions. Echinoderms species such as Culcita novaeguineae, Diadema setosum, Echinothrix calamaris, and Holothuria atra had relatively higher occurrences than other taxa. We also noted the occurrence of giant clam Hippopus hippopus, which is protected by Indonesian law. This review provides fundamental knowledge of macrozoobenthic diversity in the coral reefs of Java, making it available to global audiences. However, it revealed a lack of research on benthic fauna in several areas with moderate to good coral cover conditions. Further research is needed to explore macrozoobenthic species richness in this region thoroughly, and periodic monitoring is essential to provide early warnings of possible changes and biodiversity loss.
