Analysis of hydroids stages and their released medusa will also increase the number of species for both the We increased sampling effort at 34 coastal locations along the TEP, and combined analyses of four molecular markers and up to 53 morphological characters. Four of thcse species are endemic 10 Cocos Island. Copepods and ostracods were the dominant taxonomic groups throughout the year with a strong seasonality, furthermore 53 hydromedusae species has been found, where Liriope tetraphylla (Chamisso & Eysenhardt, 1821), Solmundella bitentaculata (Quoy & Gaimard, 1833) and Aglaura hemistoma (Péron & Lesueur, 1810), were the most abundant species. The defining characteristic of this class is that the medusa is the prominent stage in the life cycle, although there is a polyp stage present. We also examine the biodiversity of jellyfish species that are targeted for fisheries in the Americas. 62 The Scyphozoa and Cubozoa develop statocysts that generally contain biomineralic 63 crystals (statoliths). Hydrozoans are polymorphs, existing as solitary polyps, solitary medusae, or as colonies. The relationships between the classes Cubozoa and Scyphozoa, and between the orders within the Scyphozoa, are not yet well defined. by 16 species (9.5%) and the Cubozoa by 3 (1.8%). We show that surveys in regions with little information about gelatinous zooplankton may broaden our knowledge of their natural history and may result in new records of gelatinous species.Jellyfish (primarily scyphomedusae) fisheries have a long history in Asia, where jellyfish have been caught and processed as food for centuries. It is 40 therefore suggested that the Cubozoa are derived from a scyphozoan ancestor and are a highly 41 developed taxa within the Rhopaliophora. Pacific coastal zooplankton composition has been described in Bahía Salinas and Bahía Culebra. Golfo de Papagayo, a coastal upwelling region in the northern Pacific of Costa Rica. covers the Phylurn Cnidaria. For these reasons, among others, the first list of genera and species for this region is presented. El Pacífico Norte de Costa Rica es una región cambiando rápidamente y se debe contar con la información científica para una gestión sostenible de sus ambientes marinos.Within the marine zooplankton hydromedusae have a high taxonomic and an ecological significance, despite which little is known about these organisms for the Colombian Pacific Ocean (OPC). Elle possède notamment un anneau nerveux autour de la base de l'ombrelle qui coordonne ses mouvements de pulsations ; une caractéristique qui n'existe que chez les méduses du groupe des Les tentacules de certaines méduses-boîtes peuvent atteindre jusqu'à 3 mètres de longueur. 40 families, and 63 genera. Caribbean waters are also present in the country's Pacific coast. Jellyfish fisheries have been attempted in numerous countries in North, Central, and South America, with varying degrees of success. We present information of epi- and mesopelagic gelatinous zooplankton recorded by the ‘DeepSee’ submersible between 2006 and 2012 at Isla del Coco (Cocos Island), Costa Rica, an oceanic island in the Eastern Tropical Pacific. Additional surveys are needed to better understand Costa Taxonomy must represent phylogenetic relationships among taxa, but has also to be a useful tool to name taxa and one of its included aims is nomenclatural stability. Out of all cnidarians, cubozoans are the most venomous. and eight orders. Class Scyphozoa, an exclusively marine class of animals with about 200 known species, includes all the jellies. The Order Siphonophora is ¡he rnoSI diyerse with 27 spccic.". Medusa reduction is widespread in the Antho- and Leptomedusae and has occurred repeatedly in the same clade. 30 families. Español: Las medusas son animales acuáticos simples, generalmente venenosos. The local oceanography of these bays is heavily influenced by the Papagayo wind jet, which produces seasonal coastal upwelling and most likely drives the seasonal changes in zooplankton abundance and biomass. Cubozoans differ from Scyphozoans in their arrangement of tentacles; they are also known for their box-shaped medusa. 42 43 Key words: Chironex fleckeri, Periphylla periphylla, Rhopaliophora, Cubozoa, 44 Scyphozoa, phylogeny, rhopalium, statolith, bassanite 45 46 scven orders. Rodríguez-Sáenz, L. Segura-Puertas of 95% or more of water, and their bodies are usually delicate and easily damaged by traditional trawl nets used for capture, which makes identification even harder.

Se ubicaron 587 documentos sobre organismos, ambientes, y procesos marinos, oceanográficos y atmosféricos. b3.sed on unidentified specimens and personal observations. The cases of supposed inconsistent evolution considered here are: Zancleidae vs. Corynidae (similar hydroids - different medusae); Anthomedusae vs. swimming gonophores (different hydroids - similar medusae); Clytia vs. Obelia (similar hydroids - different medusae); Stomotoca vs. Hydrichthys (similar hydroids - different medusae); Zancleidae vs. Teissieridae (different hydroids - similar medusae); Clytia vs. Phialella (different hydroids - similar medusae); Mitrocomium-Campalecium vs. Encheilota-Lovenella (different hydroids - similar medusae); Eutima-Eirene vs. Eugymnanthea (similar hydroids - different medusae).

Advancing knowledge of life cycles allows identification of poly- and paraphyly in other hydrozoan groups, so that phylogenetic interpretation of some "anomalies" in the classification of Antho- and Leptomedusae is possible. The Order Siphonophora is ¡he rnoSI diyerse with 27 spccic.". The box jellyfish in the cubozoa class are able to swim against the water current and obviate themselves to be washed to the beach.

Arai: Department of Biological SciencesDespite previous research, additional work in both oceanic and coastal waters is necessary, including estuarine ecosystems, where studies on Medusozoa have not been done. The medusa is inferred to be a synapomorphy of Medusozoa. Resolution of paraphylies, however, may prove difficult. wlis is common 10 both coasls of Costa Rica.
