First register of the Tantulocarida order Boxshall and Lincoln, 1983 (Crustacea) in deep waters of the Colombian CaribbeanAbstract
Se registra por primera vez la presencia de crustáceos del orden Tantulocarida en el mar Caribe. Los organismos recolectados se encontraron parasitando a un cumáceo del género Eudorellla y a dos tanaidáceos del género Tanaella, profundidades entre 2 420 y 2 786 m de profundidad. Los organismos provienen de muestreos de la comunidad bentónica realizados en la ecorregión Caribe Oceánico (COC), en un área de interés para exploración de hidrocarburos. Los organismos se analizaron en laboratorio con microscopio óptico y estereoscopio; se tomaron fotografías y se realizaron diagramas para describir los principales caracteres morfológicos y morfométricos. En total se encontraron cuatro tantulocáridos, de los cuales uno era macho y las demás hembras sexuales. Debido a la especificidad parásito-hospedero y a que no hay reportes del orden en la región del Mar Caribe, es muy probable que los especímenes colectados sean nuevas especies para la ciencia.The presence of parasitic crustaceans of the order Tantulocarida in the Caribbean Sea is reported for the first time. The organisms were found parasitizing a Cumacea of the genus Eudorellla and two Tanaidaceans of the genus Tanaella, between 2,420 and 2,786 m deep. The organisms came from the benthic community samplings made in Ocean Caribbean ecoregion (COC), in a hydrocarbon exploration area. The organisms were analyzed in the laboratory with an optical microscope and stereoscope; photographs were taken, and diagrams were made to describe the main morphological and morphometric characters. Four tantulocaridans were found, of which one was male and the other sexual females. Due to host-parasite specificity and the lack of reports in the Caribbean Sea, it is highly likely that these collected species are new to science.
