Biodiversity of Invertebrates in Kemantren Coast, Lamongan

Abstract

Kemantren beach is located in the Kemantren Village, Paciran District, Lamongan Regency. This beach is consists of sand and coral substrate. Kemantren beach is one of the small coastal islands of Java that has already reclaimed with spot of high ecotourism potency and habitat for numerous types of invertebrate. Unfortunately, there were no previous records about invertebrate biodiversity in this area. The purpose of this research was to identify various invertebrate species inhabiting Kemantren beach, Lamongan by describing their morphological characteristics and habitat. Specimens were collected from intertidal and shallow subtidal zone using sweeping techniques along the coastal line. Morphological and habitat data were analysed descriptively. Results showed that there were seven invertebrates phyla inhabited Kemantren coastal water; Mollusca, Annelida, Porifera, Arthropoda, Echinodermata, Coelenterata, and Platyhelminthes. We had identified a total of 19 bivalves and 33 gastropods species distributed among 20 families. Invertebrate biodiversity in Kemantren coastal consisted of 100 species belonged to 79 genera, 45 families and 9 classes (Gastropoda, Bivalvia, Polychaeta, Demospongiae, Crustacea, Holothuroidea, Ophiuroidea, Anthozoa and Turbelaria). Identification of invertebrates is useful tool for biodiversity, management, conservation and development of science. We recommend exploring potential of these species as source of sustainable income for the locals.

Revealing macrozoobenthos diversity of Java coral reefs, Indonesia: a review on research trends and species assemblages

“…Few papers describe research on the macrozoobenthos of the main island of Java. Five publications describe echinoderms, mollusks, and benthic invertebrate diversity off the island's northern coast (Putri et al, 2019;Rahayu et al, 2019;Elfahmi and Efendy, 2020;Sabdono et al, 2021;Atlanta et al, 2022). Other reports describe mainly echinoderms and mollusks in Baluran National Park (Huda et al, 2017;Setiawan et al, 2019a, Setiawan et al, 2019b and in the Situbondo (Sari and Aunurohim, 2013;Somma et al, 2017), of the island's eastern coast (R5).…”

“…All studies in this region were conducted at Kepulauan Seribu; Mollusca predominated (161 species), followed by Echinodermata (74 species), Arthropoda (30 species), and Platyhelminthes (1 species). Four phyla and 99 species were reported to occur off the northern coast of East Java (R4), with the largest contribution derived from the biodiversity research conducted by Rahayu et al (2019) in the Lamongan coastal area. The most diverse taxa were Mollusca (69 species), followed by Echinodermata (15 species), Crustacea (11 species), and Platyhelminthes (4 species).…”

Diversity of bivalves on the north coast of Lamongan, East Java, Indonesia

“…Research conducted by (Hidayah and Ambarwati 2020) showed that the bivalves found in the intertidal zone of the coast of Boom Beach, Tuban consisted of 13 species dominated by Tellina timorensis. Another study conducted by Rahayu et al (2019) showed that the bivalves found in Kemantren Beach, Paciran, Lamongan consisted of six families, namely Cardidae, Veneridae, Arcidae, Cardiidae, Isognomonidae, dan Arcidae. Another study conducted by Zarkasyi et al (2016) showed that the Coastal Coast of Ujung Pangkah, Gresik, was dominated by Meretrix meretrix yellow, M. lamarckii, and Paphia undulata.…”
