In three oceanographic cruises off southern Tamaulipas (May, July and November, 1992), a total of 102 sediment samples were collected by autonomous diving at depths of 2.5 to 20.5 m, with a cylindrical 4 liter acrylic tube. The samples were sieved (aperture size 0.5 and 1.0 mm). In total, 88 species of polychaete annelids were determined (33 families); 15 species are first records for Mexico and three for the Gulf of Mexico. The dominant species were Paraprionospio pinnata, Scoletoma verrilli, Ceratocephale oculata, Aricidea finitima, Apoprionospio pygmaea, Onuphis eremita oculata and Prionospio cristata; P. pinnata was the most abundant (14.4% of the total). Highest abundance and diversity of species was in May (63 species and 622 organisms), followed by July (48 species and 401 organism); November was lowest (47 species and 217 organisms). Most diversity and abundance were found in the sandy bottoms.
在1992年5月、7月和11月于塔毛利帕斯州南部进行的三次海洋学巡航中，使用一个4升的圆柱形丙烯酸管，通过自主潜水在2.5至20.5米的深度共采集了102个沉积物样本。对样本进行了筛分（孔径为0.5毫米和1.0毫米）。总共确定了88种多毛纲环节动物（33科）；其中15种是墨西哥的首次记录，3种是墨西哥湾的首次记录。优势种为羽状拟原单指虫、韦氏斯氏虫、眼状角头虫、有限阿里虫、侏儒拟原单指虫、眼状荒漠欧努菲虫和具嵴原单指虫；羽状拟原单指虫数量最多（占总数的14.4%）。物种丰度和多样性最高的是5月（63种和生物622个），其次是7月（48种和生物401个）；11月最低（47种和生物217个）。大多数多样性和丰度出现在沙质底部。
