The Cheilostomes are the most diverse existent bryozoans group. Its species are commonly found in all the marine ecosystems around the world. In Colombia, however, information about them is scarce and limited to few localities. With the initiative of exploring the soft bottom biodiversity and completing the Colombian marine fauna inventories, INVEMAR-Macrofauna II exploration took place in March 2001, during which samples were collected on soft bottoms throughout the Colombian Caribbean from the continental shelf and the upper slope (20 – 500 m depth) by trawling. 62 species of Cheilostomes that belong to 39 families were found, 36 are first records for the Colombian Caribbean, 4 for the Great Caribbean and 1 for the Tropical West Atlantic. Bathymetric and geographic ranges are extended for 13 species. Taxonomical notes and images of the five species that are first records for the Greater Caribbean and the Tropical West Atlantic are included in this survey. It also includes remarks about the distribution, substrata, and growth types of Cheilostomata studied.

Continental shelf and upper slope fish communities were studied along the Catalan coast based on 66 experimental bottom otter trawls. A total of 79 demersal fish species were studied by means of cluster analysis and multi-dimensional scaling (MDS) ordination for community structure. Analysis revealed the existence of five major location clusters. Similarity percentage analysis (SIMPER) was determined by comparing the dissimilarity between two groups of samples using the discriminating species. Geomorphological characteristics, bottom substratum and depth showed direct influences on species assemblages. High correlation between the biotic data samples and depth was observed. The fish species assemblages identified five main demersal fish associations which corresponded with the five location clusters and with five benthic sediments (mud of the upper slope, sand and gravel, mud of the shelf, muddy-sand and sand with rocky outcrops).
