echinoid

A total of 543 species of macrobenthos were collected . the specie - number of polychaeta is 147 species , mollusca 182 species , crustacea 144 species , and echinodermata 70 species . the distribution of species of macrobenthos , their biomass and density , and biodiversity indices were described and discussed 除少數種類待鑒定外,兩次調查共發現四大類群底棲動物543種,其中多毛類39科147種,軟體動物56科182種,甲殼類41科144種,棘皮動物21科70種。

Frame - building organisms mostly are sphinctozoa , inozoa , hydrozoa , tabulozoa . binding organisms mainly are bluegreen algae , tubiphytes and tabulozoa . accessory organisms are bryozoa , brachiopoda , foraminifera , echinodermata , etc . what ' s more , biota are different with various reef facies 在各相帶內,生物組合也迥然不同,礁相以底棲生物為主,盆地相以海綿骨針、鈣球、放射蟲為特征,而礁后相則以裸海松藻、有孔蟲、蜓類、棘皮類為特征。

Echinoidea is one of the important components of echinodermata . thirty - four sea urchins were recorded in this paper , fifteen of them are recorded for the first time in china 目前對海膽食用、藥用價值的研究已日益成為熱點,在底棲生態研究方面,海膽也起著重要的作用,因此迫切需要海膽分類方面的整理工作。

The echinodermata are furnished with remarkable organs . 棘皮動物具有一種引人注意的器官。
