EEL-WORMS (NEMATODA)

S.M. Turk & P.E. Tompsett

The nematodes are small, multicellular vermiform organisms found in vast numbers in a very wide range of habitats. Those listed here represent free-living marine nematodes from the three main groups, Enoplida, Chromodorida and Monhysterida, arranged alphabetically (Crothers, 1997, Platt & Warwick, 1983; 1988; Warwick, et al. 1997). Whilst individual studies such as those carried out on the Isles of Scilly (Somerfield et al., 2007, Warwick et al., 2006), indicate an extensive fauna, data are lacking on a wider scale so that these lists are based on the best information currently available. Note that the authors only give British distribution. The assistance of R.M. Warwick is gratefully acknowledged.
