Description 457-467
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.
