“…This area is dominated by a group of starfish, which consists of four species and 61 individuals. The tube feet, which are a multiplicity of small, attachable appendages, are one of the essential morphological characteristics (Hennebert et al 2014) that aid in identification. The enormous number of individual starfish in this area, according to James (1982), is related to the high amount of habitat production that can support their growth.…”

Abstract. Siburian RHS, Tapilatu JR, Tapilatu ME. 2023. Discovery of habitat preferences and community structure of Echinoderms in Kri, Raja Ampat, Indonesia. Biodiversitas 24: 3968-3976. Raja Ampat, located in Papua, Indonesia, is home to one of the most diverse coral reef ecosystems and is a component of the Coral Triangle. The coral in Raja Ampat is still considered to be in good health. Although the marine fauna in Raja Ampat is pristine and diverse, there have still only been a few studies in this region. The scientific research on the Echinoderms in Raja Ampat is limited, particularly as a primary input for data research. In this study, we present Echinoderm's habitat and community structure in the Kri coastal area at Mansuar Island based on the data collected at field sampling. From January to February 2023, data were collected intensively during morning and afternoon low tide for three repetitions each, at 5-10 m depths. We conducted morphological species identification. Asteroidea, Holothuroidea, Echinoidea, and Crinoidea were found to be the four major classes of Echinodermata that dominated the sampling area, with a total of 20 species and 180 individuals. Each Echinodermata species has its preferred Kri coastal habitat based on its food supply, unique behavior, and body structure. In addition, the result indicates that this region has a moderate diversity level, with low dominance and moderate to high uniformity. This research provides new information on the ecology of Echinoderms in eastern Indonesia, particularly in Raja Ampat.

“…Echinodermata disebut sebagai kunci ekologi yang berperan dalam menjaga keseimbangan ekosistem laut, termasuk ekosistem lamun yang merupakan salah satu habitat bagi echinodermata (Raghunathan & Venkataraman, 2012). Secara ekologi echinodermata berperan sangat penting di ekosistem lamun, terutama dalam rantai makanan (food web) (Hermosillo-Núñez, B. B., 2020).…”

Echinoderms are benthic animals that can be found in almost all marine ecosystems but are mostly found in the intertidal coastal zone. Echinoderms play an important role as deposit feeders. This study aims to look at the distribution patterns, diversity, and habitat conditions of species in the southern coastal waters of Lombok Island, namely Kute, Awang, and Gerupuk beaches. The field survey was conducted using the quadratic transect method and free collection in October - November 2020. Based on the results of the research, a total of 11 species of echinoderms were found in Lombok Island consisting of 4 classes. Diadema setosum and Tripneusteus gratila were the most common species, whereas Synapta maculate, Holothuria leucospilota, Echinotrix diadema, Holothuria atra, and Ophiocoma scolopendrina were found in small numbers with uniform distribution (Id <1). Diadema setosum distribution pattern has the highest abundance with a clustered distribution pattern (Id> 1) in Awang and Gerupuk, and Tripneusteus gratila in Kute and Awang. The Diversity Index value is different in each habitat. The highest Shannon-Wiener Diversity Index (Hꞌ) was found in Gerupuk 2.18. The largest smoothing index is found at Awang 0.96. The largest Dominance Index (D) is found in Gerupuk 0.88. Based on the value of the Echinoderm community structure on the South Coast of Lombok Island, it shows that diversity is moderate, community uniformity is unstable, and dominance is low. information regarding the distribution and diversity of Echinoderm fauna in various types of habitats around the seagrass as a first step to anticipate the decline in the Echinoderm population in the waters of the South Coast of Lombok Island.

“…Additionally, Echinoderms interact with their environment in various ways and act as bioturbators, modifying seafloor sediments through activities like ingesting sediment, extracting organic matter during digestion, and expelling the remaining sediment, similar to the behavior of sea cucumbers. For example, large populations of sea cucumbers can result in a substantial turnover of surface sediments and lead to chemical and physical component changes in the sediment [8]. Sea cucumbers and sand dollars bury themselves in the sand, increasing the depth of oxygen and allowing for more species [9].…”

The majority of research on echinoderms in the tropics has involved coral reefs. There are relatively few studies on echinoderms connected to soft bottoms and estuaries. This work describes echinoderm species found in the soft-bottom sediments of the Wulan estuary in Demak, Indonesia, are described. Twelve species from Holothuroidea, Ophiuroidea, Asteroidea, and Echinoidea were identified. The three most prevalent species identified were Astropecten sp., P. chilensis, and Paracaudina sp. The species found differ depending on the sampling sites. Still, this knowledge expands our understanding of the richness of soft-bottom megabenthic fauna, especially the echinoderm. It could be used as a baseline to track the consequences of potential changes on this heavily sedimented river.
