Distribution of Iospilidae (Annelida) along the eastern Brazilian coast (from Bahia to Rio de Janeiro)

We present the spatial distribution and abundance of the holoplanktonic family Iospilidae (Annelida, Polychaeta), along part of the eastern Brazilian coast, and its relation to environmental variables in the region. Samples were obtained from two collections made in 1998 and 2000 between 13°-25°S, a...
