Although the LKCNHM's annelid collection is small, it contains some important specimens, including types, which have been examined and identified by various researchers. C. C. A. Monro studied the polychaetes (bristleworms), G. E. Gates worked on the oligochaetes (earthworms), and J. P. Moore examined the Hirudinea (leeches). Most of these specimens were collected from the Malay Peninsula mainly by M. W. F. Tweedie between 1930 and 1940.


A recent collection of Singapore polychaetes was made from benthic surveys carried out by the NUS's Reef Ecology Study Team for the 'ASEAN-Australia Living Coastal Resources Project'. This material, which includes new species, is deposited at the LKCNHM.
