| The epifaunal community associated with free-living colonies of Millepora alcicornis, the dominant coral species in Portete Bay, was characterized from twenty living colonies randomly collected within a shallow Thalassia testudinum seabed. The three-dimensional growth colonies sheltered 15 families, 15 genera and 18 mobile invertebrate species. The 97% of individuals was represented by decapods crustaceans specially adapted as to live in association with the host. Within them, the porcelanid Petrolisthes armatus, representing 79% of the epifauna (961 individuals), was exclusively found in a juvenile stage suggesting that M. alcicornis is mainly used by this species as a nursery zone. The epifaunal composition is partially related to coral living tissue... |

| With the aim to characterize tthe soft-bottom macrofauna and its spatial and temporal distribution patterns in the Santa Marta area, a two years sampling program was performed at depths between 7 to 60 m. Density, biomass and diversity of the community were determined. The BIOENV method was applied in order to relate the distribution of the associations and the environmental variables (depth, turbidity, organic matter, organic carbon, organic nitrogen, organic phosphorus and median particle diameter). A density of 1499 indiv *m-2 and 10.9 g*m-2 wet biomass were obtained. The collected organisms belonged to six taxa: polychaetes, crustaceans, sipunculids, molluscs, bryozoans, and echinoderms; the first one was the most important in terms of abundance and... |

| El género Steilifer se caracteriza por la ausencia de barbillones mentonianos; distancia interorbital contenida S.5 veces o menos en la longitud de la cabeza; vejiga natatoria con dos cámaras, la anterior con un par de divertículos posterotaterales; cabeza cavernosa; branquispinas largas y flexibles; otolitos sagitta y lapillus bien desarrollados. Se describe una nueva especie de Stellifer, !a cual se caracteriza por tener los divertículos de la vejiga natatoria muy pequeños, cortos y en forma de bulbo, el primer arco branquial oscuro, casi negro, con 42 a 49 branquispinas, la mayor de ellas supera en longitud al filamento branquial del ángulo del mismo arco, y por presentar cuatro poros en el mentón. Se separa de las demás especies del género por el... |

| Soft bottom megabenthic communities have been poorly studied in the Caribbean Sea. In this study we describe the structure and species composition of a Crustacea-Mollusca megafaunal community based on beam trawl samples taken between 13 and 60 m depth at the southwestern region of Santa Marta, Colombian Caribbean. Classification and ordination analyses using abundance data of crustaceans and molluscs produced two main groups (A and C), which seem to be controlled by depth and sediment characteristics. Group A consisted of species collected at the deeper stations and high content of silts (between 30 and 60 m depth) and exhibited the highest density and biomass mean values. The decapod Chasmocarcinus cilindricus was found as the characteristic species for... |
