Paraeuchaeta gracilis (Sars G. O. 1905)

Euchaeta gracilis Sars, 1905

This is a common euchaetid species in deep waters of the North Atlantic from the tropical to boreal region (Vervoort, 1963). It has also been recorded from the Indian Ocean by De Decker and Mombeck (1965) and Grice and Hulsemann (1967) and from the Pacific by Wilson (1950).

In the Gulf of Mexico and Caribbean Sea, E. gracilis has been recorded by Grice (1969). In the present study, the species was represented by 32 females and 8 males, most of which were found in the samples obtained from a depth range of 500 to 1000 m. The female measured 6.00–6.66 mm in body length and 4.20–4.75 mm in prosome length, and the male 5.08–5.58 mm in body length and 3.66–4.00 mm in prosome length.
