Euchaeta bisinuata Sars, 1907

This is one of the more common bathypelagic euchaetid species throughout the tropical, subtropical, and temperate zones of the World Ocean. In the Gulf of Mexico and western Caribbean Sea, it was found to be the most common euchaetid species in the bathypelagial zone. Altogether, 234 females and 42 males were identified in the present study, most of which were found from a depth range below 1000 m. The female measured 5.17–5.58 mm in body length and 3.67–4.04 mm in prosome length, and the male 4.48–4.75 mm in body length and 3.32–3.60 mm in prosome length.
