Echinoids and Crinoids from Terra Nova Bay (Ross Sea) Based on a Reverse Taxonomy Approach

The identification of species present in an ecosystem and the assessment a faunistic inventory is first step any ecological survey conservation effort. Thanks to technological progress, DNA barcoding has sped up great support morphological taxonomy. In this work, we used “Reverse Taxonomy” approach, where molecular (DNA barcoding) analyses were followed by (skeletal features) ones determine specific status 70 echinoid 22 crinoid specimens, collected during eight different expeditions Ross Weddell Seas. Of total 13 sea urchins, 6 from Terra Nova Bay area (TNB, Sea) 4 crinoids identified. Previous scientific literature reported only four urchins TNB which added records Abatus cordatus (Verrill, 1876), curvidens Mortensen, 1936 ingens Koehler, 1926. Moreover, found previous misidentification koehleri (Thiéry, 1909), erroneously as A. elongatus publication for area. All are new there was no available TNB.
