Abstract

This review gives an overview of advances in the study of gelatinous zooplankton in the Eastern Tropical Pacific area. The review provides a brief description of the main phylums that make up the gelatinous zooplankton, Cnidaria and Ctenofora, and about the Thaliacea class, belonging to the subphylum Urochordata, whose members are present in this area. In addition, we made a comparison of benefits and limitations of traditional capture and study methods versus molecular methods based on the following criteria: sensitivity, specificity, probability of false results (false positive and false negative), invasiveness and cost. Finally, we review and summarize the available information of gelatinous zooplankton for the Eastern Tropical Pacific (PET) related to collection methods, and species list for the region. PET has an elevated marine biodiversity and ideal physical and chemical conditions for the development of zooplankton communities; however, studies on these taxa are reduced. Therefore, it is necessary to carry out more studies of this group in this zone including both traditional and molecular methods to efficiently understand populations, their dynamics, demographic connectivity and behavior in more detail. The application of molecular methods in these species will provide a base line of molecular data that will allow scientists to establish evolutionary and conservation units, assess genetic diversity, understand the effective population size of their populations and the identification of genetic connectivity and gene flow areas.
