摘要：
Sediments were collected at fifteen stations in five transects at Chetumal Bay (June and December 1995). Sediments were medium and fine sands with 15.62% organic matter. In June, 2 239 individuals represented 20 families and 37 genera; in December 1 426 individuals represented 21 families and 35 genera. Neotonchoides, Desmodora, Bathylaimus, Pseudochromadora, Desmolaimus, Chromadorina and Steineria were the most abundant. In both months the same transect had the highest abundance and richness (957 and 744 individuals, 28 and 25 genera, respectively). The lowest abundance in a transect was 48 individuals and six genera. Diversity fluctuated among 0.53 and 2.53 beles/ind. In general, the genus composition;in Chetumal bay is homogeneous. The noteworthy occurrence of marine genera in this brackish environment shows their adaptability.
