Abstract

Salaya beach is a beach that has the variety of see-animals that have not discovered and identified especially Echinoidea and Asteroidea it is rocky coast area and rarely planted by sea grass and algae and also sandy area. Some Echinoidea species is a kind of kommodity waters used as food, part of this animal usually used is gonad or egg. Basides Echinoidea and Asteroidea have important role, keep the balance of ecosystem waters, and can be called as detritus eater so that the waters become clean. The purpose of this reseach is to know the species from classis Echinoidea and Asteroidea existing on Salaya beach Kilo district Dompu-NTB, and also to know the variety, spreading patterns, and ecological characteristic of Echinoidea and Asteroidea classis. The observation is taxen with drect observation, and use square transect method. It use descriptive reseach and the sampling techniqve is simple random sampling, the way to take the sample is got randomly. The result of this reseach is 5 species from classis Echinoidea, they are Diadema savignyi Michelin, Echinometra mathaei Blainville, Echinothrix calamaris Pallas, Tripneustes gratilla Linnaeus, and Toxopneustes pileolus Lamarck. And 4 species classis Asterpoidea, they are Protoreaster nodosus, Astropecten preissi, Linckia laevigata Linnaeus, and Culcita novaeguineae Muller. The total of Echinoidea and Asteroidea species, found at ebbtide area Salaya beach Kilo district Dompu-NTB are 9 species. The variety of Echinoidea and Asteroidea are very low with Shannon-Wiener variety value is 0,724 and the equilization index value (Evenness) is 0,777 wich means the equilization of Echinoidea and Asteroidea are medium. For spreading patterns value based on Morisita index of all species spread flat. Based on the calculation of ecological characteristic, species that dominate Salaya beach Kilo district Dompu-NTB is Diadema savignyi Michelin becouse ecolocally Salaya bech has the environment that supports a kind of this species life.
