Title

Faunal composition of metazoan meiofauna from the southeast continental shelf of India

Abstract

Analysis of the faunal composition of meiobenthos in the sediments of the southeast continental shelf of India showed nine taxonomic groups. Among these, nematoda, copepod and foraminifera were dominant. As many as 192 species of free-living marine nematodes, 39 species of harpacticoid copepods and 39 species of foraminiferans were identified. Other groups of metazoans encountered were polychaetes, ostracods, isopods, cumaceans, tanaidacea and tardigarda. Free-living marine nematodes constituted 57.63% of the total meiofaunal organisms. Harpacticoid copepods, foraminiferans and others constituted 14.77%, 13.89% and 13.71% respectively. Xyalidae, Desmodoridae, Comesomatidae and Linhomoeidae were the most dominant families of nematodes. These families were represented in all the depths. The abundance of nematodes showed a decrease with increase in depth (207.7±19.2 no. of ind. /10 cm² at 30-50 m depth to 34.6±6.5 no. of ind. /10cm² at >175 m depth). Similarly the number species also decreased with increase in depth (from 151 species at 30-50 m depth to 58 species at >175 m depth). More number of species were found in the Southern part of the study area than the Northern part.
