The presence of Sphyrna tudes in Colombian waters is supported by a 506 mm total length male collected in the southernmost corner of the Caribbean Sea, the mouth of Atrato river. A short discussion on the confusing taxonomic and nomenclatural history of the smalleye hammerhead is included.

The pygmy killer whale (Feresa attenuata) is an offshore, tropical and subtropical delphinid found in the Atlantic, Indian and Pacific Oceans. The species has only recently been studied, mostly from specimens collected from strandings. While over 52 reports exist for the Atlantic Ocean, only one record exists for the Caribbean Sea. A new record of a mass stranding of pygmy killer whales from the British Virgin Islands is documented and the pathology and life history of the specimens is described, associating the stranding process with the meteorological and oceanographic disturbance of Hurricane Marilyn, which devastated the Virgin Islands a day prior to the stranding. This stranding event constitutes the sixth known mass stranding for the species worldwide, the first record for pygmy killer whales for the northeastern Caribbean and the second for the entire Caribbean Sea.

A list of all known polychaete species reported in the primary literature is presented for the Caribbean Sea. The most spe-cies-rich polychaete faunas are those of Cuba in the North Caribbean ecoregion and Trinidad-Tobago and Colombia in theSouth Caribbean ecoregion while the ecoregion with the greatest number of species is the Greater Antilles. While part ofthe explanation for these higher diversity areas may be due to collection effort, these areas may also be higher in speciesnumber as a result of being ecotones between the Gulf of Mexico in the north and the northern South American region tothe south. The most species-rich families are the Syllidae, Eunicidae, Nereididae, Polynoidae, Sabellidae, Serpulidae, Ter-ebellidae, and Spionidae. A brief discussion of the history of polychaete research identified many of the more importantworkers in the characterization of the polychaete fauna of the region. An analysis of the species-record accumulation curvefor polychaetes indicated that this fauna has not yet been fully characterized. One portion of the polychaete fauna identified as being especially poorly known is that from the deep-water areas of the Caribbean.

As part of monitoring in the estuarine inner Bay of Cartagena, Colombia during the year 2016, a female adult specimen ofCymbasoma chelemense was collected and identified. Originally described for the Gulf of Mexico and sharing the followingmorphological and morphometric characteristics: Cephalothorax of at least 68% of the total length of the body. Oral papilla located at least 20% of the total length of the cephalothorax; Ocelli present; genital complex with ovigerous spines located at the base and with one single post genital somites, the ovigerous spines at least 14% longer than the total length of the body and about 10 times the length of urosome. This is the first record of a copepod of the genus Cymbasoma in Colombia estuarine waters, increasing the range of distribution of this species in the Caribbean Sea.

It is not surprising that prior to the construction of the Panama Canal, Nicaragua was considered of strategic importance to the world's major sea powers. Together the Río San Juan and Lake Nicaragua provide a water passage from the Caribbean Sea to within 20 kilometers of the Pacific Ocean (see map). In addition to its obvious inter-oceanic canal potential, this water passage was primarily useful for hundreds of years as an alternate route for the pirate-threatened Central American colonial commerce.A remarkable number of historical and geographical misconceptions have appeared in the literature concerning this river. The recent publication of the seventeen-volume Colección Somoza containing documents relating to the history of Nicaragua from 1503 to 1550 does much to clarify this period of exploration and navigation.

AbstractRelationships between animals and their associated microbiota is dependent on the evolutionary history of the host and on the environment. The majority of studies tend to focus on one of these factors and rarely consider how both determine the community composition of the associated bacteria. One “natural experiment” to test how evolutionary history, shared environments, and the interaction between these factors drive community composition is to compare geminate species pairs. Echinoids separated by the Isthmus of Panama are suitable for this comparison due to the known evolutionary history and differences in oceanographic characteristics of the Caribbean Sea and Pacific Ocean. By comparing the egg-associated microbiota for the Echinometra and Diadema geminate species pairs, we show that both pairs of geminate species associate with distinct bacterial communities in patterns consistent with phylosymbiosis, and that the interaction between the evolutionary history of the host and the environment best explain differences in these communities. Moreover, we find that particular microbial taxa differed considerably between, but not within, oceans and that the microbiota of the two Caribbean Echinometra species were dominated by the phototrophic Oxyphotobacteria.

The announcement of Panama as host of World Youth Day in 2019, turned out to be a great surprise for the whole world. For the fi rst time such a small country, has hosted a global event. Panamá is known primarily from the Panama Canal and the Panamanian aff air called Panama. But speaking in these two contexts is very hurtful, because it is a country richly diverse, and the Church here has a unique, unique face. Catholic missions are included in the history of Panama from the very beginning. From the beginning of the bishopric in the city of Panamá, through the territorial development of the Church, everything here has a mark of mission. The fi nal element of the article is the presentation of the Church in the Bocas del Toro Territorial Prelature. The prelature is located in the Caribbean Sea and is geographically diff erent from the rest of the country. But this place is an example of a missionary church, and of a church that needs support in its mission. Poles coming to Panama for the next World Youth Day will discover a unique country, and together with the Poles, Panama will be discovered by the whole world.
