Morphology and Anatomy:

Genus characterized by:

Nematodes of the subfamily Sabatieriinae generally have a weakly sclerotized buccal cavity with the posterior section as a collapsed tube, spicules enlarged proximally, gubernacular apophyses paired or single.
Anterior and posterior cephalic sensilla closely spaced, posterior setae usually longer than anterior.
Buccal cavity small, three small teeth may appear as weak cuticularization at base of anterior buccal cavity.
Tail elongate, posterior section filiform.

Distribution:

Described from subtidal sediment habitats.

Laimella spp. are frequently recorded, although usually in low numbers, in muddy or fine sand sediments from the intertidal and estuarine habitats to the deep sea (Barnes et al., 2012; Moreno et al., 2008; Miljutina et al., 2010).
