  1. The species are classified according to their constancy of occurrence, successional characteristic, days of exposure that presented the highest density, and compound size (sum of the mean zooid length, mean zooid width at midpoint, mean basal stalk length, and mean basal stalk width; in micrometers). Species present in more than 50% of collections were named as constant, those between 25% and 49% were considered accessory, and those occurring in less than 25% were named casual. Pioneer species were considered those whose maximum occurrences were recorded by the 30th day of exposure of the traps in the water; secondary species were those that had their maximums between the 30th and 60th days of exposure, and climax were considered the species that presented maximum occurrence after the 60th day of exposure.
