Abstract: Despite the important effort of knowing the Ophiuroidea diversity in the Mexican Pacific, some mis- takes in the taxonomic nomenclature have pervaded through time. In order to clarify the latter, a checklist based on literature review of brittle stars from the Mexican Pacific is provided. We reviewed a total of 105 references that in total summarized 125 species of brittle stars from the Mexican Pacific (112) and the Gulf of California (97), belonging to two orders, 16 families and 50 genera. These records are higher than those reported on previ- ous studies carried out in the area.

  • Hemichordate Phylogeny: a Molecular, and Genomic Approach By
    Hemichordate Phylogeny: A molecular, and genomic approach by Johanna Taylor Cannon A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama May 4, 2014 Keywords: phylogeny, evolution, Hemichordata, bioinformatics, invertebrates Copyright 2014 by Johanna Taylor Cannon Approved by Kenneth M. Halanych, Chair, Professor of Biological Sciences Jason Bond, Associate Professor of Biological Sciences Leslie Goertzen, Associate Professor of Biological Sciences Scott Santos, Associate Professor of Biological Sciences Abstract The phylogenetic relationships within Hemichordata are significant for understanding the evolution of the deuterostomes. Hemichordates possess several important morphological structures in common with chordates, and they have been fixtures in hypotheses on chordate origins for over 100 years. However, current evidence points to a sister relationship between echinoderms and hemichordates, indicating that these chordate-like features were likely present in the last common ancestor of these groups. Therefore, Hemichordata should be highly informative for studying deuterostome character evolution. Despite their importance for understanding the evolution of chordate-like morphological and developmental features, relationships within hemichordates have been poorly studied. At present, Hemichordata is divided into two classes, the solitary, free-living enteropneust worms, and the colonial, tube- dwelling Pterobranchia. The objective of this dissertation is to elucidate the evolutionary relationships of Hemichordata using multiple datasets. Chapter 1 provides an introduction to Hemichordata and outlines the objectives for the dissertation research. Chapter 2 presents a molecular phylogeny of hemichordates based on nuclear ribosomal 18S rDNA and two mitochondrial genes. In this chapter, we suggest that deep-sea family Saxipendiidae is nested within Harrimaniidae, and Torquaratoridae is affiliated with Ptychoderidae.

Biol. 33(2) : 205~208 (2015) http://dx.doi.org/10.11626/KJEB.2015.33.2.205 A Newly Recorded Basket Star of Genus Gorgonocephalus (Ophiuroidea: Euryalida: Gorgonocephalidae) from Korea Donghwan Kim and Sook Shin* Department of Life Science, Sahmyook University, Seoul 139-742, Korea Abstract - Some euryalid specimens were collected with fishing nets from Mipo, Gyungsangnam- do and Aewol, Jejudo Island, Korea. They were identified as Gorgonocephalus eucnemis (Müller & Troschel, 1842), belonging to family Gorgonocephalidae of order Euryalida, which was new to the Korean fauna. Their molecular analyses were done with newly intended COI primers of mitochondrial cytochrome oxidase I (COI) gene for the accurate molecular identification. The Korean G. eucnemis was coincident with this NCBI species as a result of Blast analysis, which showed the 99% similarity. In the current study, three Gorgonocephalus species have been report- ed from Korea. Key words: Gorgonocephalus‌ eucnemis, basket star, morphology, molecular analysis, Korea INTRODUCTION MATERIALS AND METHODS Family Gorgonocephalidae including 34 genera is the Basket stars were collected at a depth of 100~150 m deep largest one of three families belonging to order Euryalida by fishing nets from Mipo, Korea Strait and Aewol, Jejudo (Okanishi and Fujita 2013) and its four genera, Astroboa, Island, Korea on June 1983 and January 2013, respectively.

Almost all Gorgono- identified on the basis of morphological characteristics and cephalus species distribute exclusively in deep water and are molecular analyses.
