Adhesion in Echinoderms

Among 1 these mechanisms, one can distinguish between mechanical attachments (e.g. hooks or suckers) and chemical attachments (with adhesive sub- stances). The phylum Echinodermata is quite exceptional in that all its species, *Senior research assistant, National Fund for Scientific Research, Belgium. I whatever their life style, use attachment mechanisms. These mechanisms allow some of them to move, others to feed, and others to burrow in par- ticulate substrata. In echinoderms, adhesivity is usually the function of specialized structures, the podia or tube-feet. These podia are the exter- nal appendages of the arnbulacral system and are also probably the most advanced hydraulic structures in the animal kingdom. 2 THE PODIA From their presumed origin as simple respiratory evaginations of the am- bulacral system (Nichols 1962), podia have diversified into the wide range of specialized structures found in extant echinoderms. This mor- phological diversity of form reflects the variety of functions that podia perform (Lawrence 1987). Indeed, they take part in locomotion, burrow- ing, feeding, sensory perception and respiration. -

Benthic Invertebrate Community Monitoring and Indicator Development for Barnegat Bay-Little Egg Harbor Estuary
July 15, 2013 Final Report Project SR12-002: Benthic Invertebrate Community Monitoring and Indicator Development for Barnegat Bay-Little Egg Harbor Estuary Gary L. Taghon, Rutgers University, Project Manager [email protected] Judith P. Grassle, Rutgers University, Co-Manager [email protected] Charlotte M. Fuller, Rutgers University, Co-Manager [email protected] Rosemarie F. Petrecca, Rutgers University, Co-Manager and Quality Assurance Officer [email protected] Patricia Ramey, Senckenberg Research Institute and Natural History Museum, Frankfurt Germany, Co-Manager [email protected] Thomas Belton, NJDEP Project Manager and NJDEP Research Coordinator [email protected] Marc Ferko, NJDEP Quality Assurance Officer [email protected] Bob Schuster, NJDEP Bureau of Marine Water Monitoring [email protected] Introduction The Barnegat Bay ecosystem is potentially under stress from human impacts, which have increased over the past several decades. Benthic macroinvertebrates are commonly included in studies to monitor the effects of human and natural stresses on marine and estuarine ecosystems. There are several reasons for this. Macroinvertebrates (here defined as animals retained on a 0.5-mm mesh sieve) are abundant in most coastal and estuarine sediments, typically on the order of 103 to 104 per meter squared. Benthic communities are typically composed of many taxa from different phyla, and quantitative measures of community diversity (e.g., Rosenberg et al. 2004) and the relative abundance of animals with different feeding behaviors (e.g., Weisberg et al. 1997, Pelletier et al. 2010), can be used to evaluate ecosystem health. Because most benthic invertebrates are sedentary as adults, they function as integrators, over periods of months to years, of the properties of their environment. -
The Taxonomic Challenge Posed by the Antarctic Echinoids Abatus Bidens and Abatus Cavernosus (Schizasteridae, Echinoidea)

Additions to and Revisions of the Amphipod (Crustacea: Amphipoda) Fauna of South Africa, with a List of Currently Known Species from the Region
Additions to and revisions of the amphipod (Crustacea: Amphipoda) fauna of South Africa, with a list of currently known species from the region Rebecca Milne Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa & Charles L. Griffiths* Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa E-mail: [email protected] (with 13 figures) Received 25 June 2013. Accepted 23 August 2013 Three species of marine Amphipoda, Peramphithoe africana, Varohios serratus and Ceradocus isimangaliso, are described as new to science and an additional 13 species are recorded from South Africa for the first time. Twelve of these new records originate from collecting expeditions to Sodwana Bay in northern KwaZulu-Natal, while one is an introduced species newly recorded from Simon’s Town Harbour. In addition, we collate all additions and revisions to the regional amphipod fauna that have taken place since the last major monographs of each group and produce a comprehensive, updated faunal list for the region. A total of 483 amphipod species are currently recognized from continental South Africa and its Exclusive Economic Zone . Of these, 35 are restricted to freshwater habitats, seven are terrestrial forms, and the remainder either marine or estuarine. The fauna includes 117 members of the suborder Corophiidea, 260 of the suborder Gammaridea, 105 of the suborder Hyperiidea and a single described representative of the suborder Ingolfiellidea. -

Muñoz and Londoño-Cruz Marine Biodiversity Records (2016) 9:67 DOI 10.1186/s41200-016-0022-9 RECORD Open Access First record of the irregular sea urchin Lovenia cordiformis (Echinodermata: Spatangoida: Loveniidae) in Colombia C. G. Muñoz1* and E. Londoño-Cruz1,2 Abstract Background: A first record of occurrence of the irregular sea urchin Lovenia cordiformis in the Colombian Pacific is herein reported. Results: We collected one specimen of Lovenia cordiformis at Gorgona Island (Colombia) in a shallow sandy bottom next to a coral reef. Basic morphological data and images of the collected specimen are presented. The specimen now lies at the Echinoderm Collection of the Marine Biology Section at Universidad del Valle (Cali, Colombia; Tag Code UNIVALLE: CRBMeq-UV: 2014–001). Conclusions: This report fills a gap in and completes the distribution of the species along the entire coast of the Panamic Province in the Tropical Eastern Pacific, updating the echinoderm richness for Colombia to 384 species.
