Abstract

DURAN-GONZALEZ, Alicia et al. Biodiversidad de ofiuroideos (Echinodermata: Ophiuroidea) del talud de la Península de Yucatán, México. Rev. biol. trop [online]. 2021, vol.69, suppl.1, pp.132-153. ISSN 0034-7744.  http://dx.doi.org/10.15517/rbt.v69isuppl.1.46337.

Introduction:

The Ophiuroidea class is the most diverse of the Phylum Echinodermata, with 2 064 described species, which can be found from intertidal zones to abyssal depths, but the fauna of Yucatan peninsula needs more study.

Objective:

To describe the diversity of ophiuroids in the Yucatan continental slope.

Methods:

Information was compiled from four oceanographic surveys carried out in August 2005, June 2007 (BIOREPES 1 and 2: BRP1 and BRP2), April 2011 and August 2014 (COBERPES 2 and 6: CBP2 and CBP6). The specimens were obtained by trawling with a shrimp net in soft substrates and with a skimmer-type trawl dredge at a depth range of 200 to 1 071 m off the states of Yucatán and Quintana Roo, Mexico.

Results:

We found members of two superorders, five orders, six suborders, five superfamilies, 18 families, 28 genera and 43 species.

Conclusions:

The northeast zone Yucatan Peninsula has at least 43 species, of which 19 are new records for the area.

Keywords : taxonomy; new records; deep sea; Gulf of Mexico.
