A study on the distribution and abundance of annelida was conducted at estuaries of<br />

Merang jetty and Kuala Ibai, Terengganu. A total number of 6 substations had been<br />

plotted in this estuaries area. The annelida samples were collected using 0.1 m 2 . Ponar<br />

grab and sieved by through 0.5 mm mesh sieve. Then, the collected organisms were<br />

preserved in 10% of formalin before been brought to laboratory for further analysis.<br />

The highest percentages of organic content were recorded in sub-station. The highest<br />

annelida abundance was at station M1 with 16 organisms and lowest was at station<br />

K2 with 1 organisms. The total abundance of annelida collected was about 35 at<br />

Merang Jetty and 10 at Kuala ibai and the highest abundance belong to family<br />

Capitellidae. In conclusion, concentrated human activity give impact to annelida<br />

community. It can be defined that annelida in Merang Jetty have highest abundance<br />

compared to Kuala Ibai which host low human activity.<br />
