Depth range Low water to about 30 m. Specimens collected swimming at the surface. [details]
Distribution Atlantic coast of the USA. Records from other areas need confirmation. [details]
Etymology Not stated. The specific epithet arenaceodentata is composed by the Latin word arenaceo, form of the adjective arenaceus and meaning 'sandy' or 'covered with sand', and the Latin adjective dentata (masculine: dentatus), meaning 'toothed' or 'having teeth'. It refers presumably to the disposition and appearance of the paragnaths on the areas V-VIII of the basal ring of the proboscis, described as follows: ''All of the areas of the basal ring have united into a continuous zone somewhat narrower on the dorsum, covered thickly and uniformly with small, grainlike, bluntly conical, horny papillae'' (Moore, 1903: 722). [details]
Habitat Mussel beds just below low water. [details]
Reproduction It lacks a heteronereis stage, but immature and mature specimens were found swimming at the surface of Woods Hole Harbor and Vineyard Sound during late August (1882, 1902, 1903, 1904) and October (1882). Mature ova observed in the coelom of many specimens. [details]
