They shared only 7.8% of the species found; which might have profound and interesting effects for conservation purposes.

Introduction echinoderms and are, at best, incomplete. A checklist of regional marine species has many uses. Additionally, it has been suggested that the number of Further to providing base line information and important species recorded for these groups represent only 50% of data for comparative studies on biodiversity it also plays an the total richness expected for Colombia (Díaz and Acero important role and is an important tool in the recognition 2003). and delimitation of areas with need protecting, in the Considering the incomplete knowledge of the process to infer damage and impacts of anthropogenic biodiversity associated to the intertidal and shallow subtidal activity, in the assessment of the complexity of biological marine ecosystems, the aim of this survey was to produce communities, and in the estimation of resource availability a preliminary checklist of marine macroinvertebrates inhabiting two localities of Malaga Bay (Isla Palma and It is known that comprehensive evaluations and Los Negritos). Mollusks and crustaceans were sampled as inventories(Hendrickx and serve Harvey as the1999). basis for local practices of well although they are the most common in the conservation, which is relevant in poorly known areas in intertidal and shallow subtidal habitats.

Data collection and identification the Reference Collection of Marine Biology – Universidad At each site, samples were collected by intensive Results and Discussion scrutiny of animals hidden in cracks and under stones, A total of 128 species of marine invertebrates both in the subtidal and shallow subtidal, where the sampling was performed using SCUBA and snorkeling. faunal composition was distributed in 10 groups, with At Isla Palma, the submerged walls of the cliffs were belonging to 64 families were collected (Table 1). The also sampled and some boulders were extracted to look Only 7.8% (10 species) was shared between the two for infauna (e.g. polychaets, mytilid bivalves and alpheid places.64.1% Within found inthe Isla species Palma found, and the 40.6% presence in Los of 3 Negritos. species shrimps).
