Description
Summary:The biogeographical distribution of the benthic hydroid species collected during the Spanish Antarctic expedition Antártida 8611 has been studied. An inventory of the Antarctic and Magellan benthic thecate hydroid faunas, along with a comparison between the two, have been also carried out. 104 and 126 species of thecate hydroids have been considered in the Antarctic and Magellan areas, respectively. 72 species (69%) of the Antarctic species and 49 (39%) of the Magellan species are endemic. 23 species are present both in the Antarctic Region and in the Magellan area, representing 22% and 18% respectively, and indicating an important relationship between both faunas. Se ha estudiado la distribución biogeográfica de las especies de hidrozoos bentónicos recogidos durante la campaña de prospección científico-pesquera “Antártida 8611”. Asimismo, se ha realizado un inventario de la fauna de hidrozoos tecados bentónicos antárticos y magallánicos, habiéndose llevado a cabo una comparación entre ambas faunas. 104 y 126 especies de hidrozoos tecados se han considerado en las áreas antártica y magallánica respectivamente. 72 especies (69%) de las especies antárticas y 49 (39%) de las magallánicas son endémicas. 23 especies están presentes en ambas regiones, representando un 22% y un 18% respectivamente e indicando una importante relación entre ambas faunas.
