Abstract

Indonesia is a maritime country with high diversity of marine biota, which one is from Phylum Echinoderms. Echinoderms are known as biota of marine which is are living on corals, sandy, and on the intertidal zone and deep ocean. The intertidal characteristics of Sundak Beach has a suitable structure to echinodems life because there are many corals, but there is many species has not been identified before. The purpose of this research is to know the diversity of echinoderms phylum on the intertidal zone. Sampling was carried out on August, 24th 2019 with purposive random sampling method along the coastal-line in intertidal zone. The result of this research are identified and classified on the each class. Based on the results, the are found species from Echinodea, Holothuroidea, and Ophiuroidea. Species from Echinoidea are Tripneustes gratilla, Echinometra mathaei, Heterocentrotus trigonarius, Diadema antillarum., and Echinothrix calamaris. Holothuroidea namely Holothuria atra. Ophiuroidea namely Ophiotrix fragilis, Ophiocoma scolopendrina, and Ophiocoma erinaceus. The conclusion from this study is the discovery of five species from class Echinoidea, one species from class Holothuroidea and three species from class Ophiuroidea.

Highlights

Research on the diversity of members of the Echinoderms phylum has never been done, this study aims to learn more about the diversity of echinoderms on the Sundak beach along with the character of each species found
RESULT AND DISCUSSION Based on the research, there are seven species of Echinoderms that found in Sundak Beach, Gunung Kidul, Yogyakarta that presented in the table below

Summary

INTRODUCTION

Indonesia is one of the countries with a high diversity of marine life, one of those is Echinoderms. Echinoderms are marine exlusive organisms that can be found in the intertidal zone to deep-sea areas. Echinoderms devided into five major classes, namely Asteroidea containing a variety of starfish, Crinoidea which are often referred to as sea lilies, Echinoidea which includes sea urchins, sand dollars, and sea biscuits, Holothuroidea or sea cucumbers, and Ophiuroidea or brittle stars Organisms of crinoidea can be found in the deep sea only It has lilies-like form with stalk organ (cirri) used to attach on the substrate (Eleaume et al 2016). Echinoidea composed of ten double columns of plates; five in ambulacral and five in the alternating interambulacral This class has a hollow shape composed of internal skeletons. Many marine biota is found, one of them is the member of the Echinoderms. Research on the diversity of members of the Echinoderms phylum has never been done, this study aims to learn more about the diversity of echinoderms on the Sundak beach along with the character of each species found
