Abstract

CORTES, Juan Sebastián; CAMPOS, Néstor Hernando  and  BOLANO-LARA, Maryela. First register of the Tantulocarida order Boxshall and Lincoln, 1983 (Crustacea) in deep waters of the Colombian Caribbean. Bol. Invest. Mar. Cost. [online]. 2021, vol.50, n.1, pp.171-178.  Epub Sep 19, 2021. ISSN 0122-9761.  https://doi.org/10.25268/bimc.invemar.2021.50.1.1007.

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.
