CHAPTERS These include species-rich taxa such as Nematoda and Platyhelminthes, and as taxa with few or even only one species, such as Micrognathozoa (Limnognathia maerski) and Cycliophora (Symbion pandora). All Acanthocephala and subgroups of Platyhelminthes and Nematoda, are parasites that often exhibit complex life cycles. Most of the taxa described are marine, but some have also invaded freshwater or the terrestrial environment. “Aschelminthes” are not a natural group, instead, two taxa have been recognized that were earlier summarized under this name. Gnathifera include taxa with a conspicuous jaw apparatus such as Gnathostomulida, Micrognathozoa, and Rotifera. Although they do not possess a jaw apparatus, Acanthocephala also belong to Gnathifera due to their epidermal structure. ©Encyclopedia of Life Support Systems (EOLSS) BIOLOGICAL SCIENCE FUNDAMENTALS AND SYSTEMATICS – Vol.

    Received: 27 August 2018 | Accepted: 28 August 2018 DOI: 10.1111/zsc.12317 LETTER TO THE EDITOR Nemertean taxonomy—Implementing changes in the higher ranks, dismissing Anopla and Enopla Dear Editor, José E. Alfaya3 Nemertean classification has closely followed Stiasny‐ Fernando Ángel Fernández‐Álvarez4 Wijnhoff’s scheme (1936) that was based on Schultze’s Håkan S Andersson5 (1851) division of the taxon into the two classes Anopla and Sonia C. S. Andrade6 Enopla. In August 2018, the 9th International Conference of Thomas Bartolomaeus7 Nemertean Biology took place in the Wadden Sea Station of Patrick Beckers7 the Alfred Wegener Institute in List auf Sylt, Germany. At Gregorio Bigatti3 this meeting, the community reached consensus to revise ne- Irina Cherneva8 mertean taxonomy at the class level, based on the compiled Alexey Chernyshev9,10 evidence from studies on nemertean systematics published Brian M. Chung11 in the last 15 years (Andrade et al., 2014, 2012 ; Thollesson Jörn von Döhren7 & Norenburg, 2003). Previous classifications (e.g., Stiasny‐ Gonzalo Giribet12 Wijnhoff, 1936) are not based on phylogenetic grounds, and Jaime Gonzalez‐Cueto13 the use of these names is therefore nowadays not wholly in- Alfonso Herrera‐Bachiller14 formative.

  • THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
    August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject.

Introduction Any treatment of durophagous (shell-breaking) predation on bivalves and gastropods through geologic time must address the molluscivore's signature preserved in the victim's skeleton. Pre-ingestive breakage or crushing is only one of four methods of molluscivory (Vermeij, 1987; Harper and Skelton, 1993), the others being whole­ organism ingestion, insertion and extraction, and boring. Other authors in this volume treat the last behavior, whereas whole-organism ingestion, and insertion and extraction, however common, are unlikely to leave preservable evidence. Bivalve and gastropod ecologists and paleoecologists reconstruct predator-prey relationships based primarily on two, although not equally useful, categories of pre-ingestive breakage, namely lethal and sublethal (repaired) damage.

  • Phylum Nemertea Or Rhynchocoela (Minor Phyla)
    Animal Diversity: (Non-Chordates) Phylum Nemertea or Rhynchocoela (Minor Phyla) Hardeep Kaur Assistant Professor, Department of Zoology, Ramjas College, University of Delhi Delhi – 110 007 CONTENTs: ¾ Introduction ¾ External Structure ¾ Body Wall and Locomotion ¾ Nutrition and Digestive System ¾ Circulatory System ¾ Excretory System ¾ Nervous System and Sense Organs ¾ Regeneration ¾ Reproductive System ¾ Embryogeny ¾ Classification of Nemerteans ¾ General Characters of Nemerteans ¾ Affinities of Nemerteans ¾ Glossary ¾ References / Suggested Readings PHYLUM NEMERTEA / PHYLUM RHYNCHOCOELA INTRODUCTION: Phylum Nemertea comprises approximately 1200 species of ¾ elongated and often flattened worms, called ribbon worms (many have flattened body) or ¾ bottle worms (because of narrow anterior end) ¾ proboscis worms, (because of the presence of a remarkable proboscis apparatus used in capturing food). The Nemerteans are named for Nemertes, one of the Nereids, sea-nymph of Greek mythology. They are commonly looked upon related to the Turbellaria and were formerly included in them, but the fact that they possess a complete digestive system with anus and also a blood vascular system makes them higher in organization than the Turbellaria. However, presence of a protrusible proboscis with a separate proboscis pore, other than mouth, is the most characteristic feature of the phylum. Almost all nemerteans are free living, bottom-dwelling, marine animals. Few commensal and parasitic species have been described. Nemertopsis actinophila is a slender form living beneath the pedal disc of sea anemones. Carcinonmertes may be found on gills and egg masses of crabs. Some species of Tetrastemma live in the branchial cavity of tunicates. Only few exibit commensal mode of life eg. Gonomertes parasitica is a commensal species found on crustaceans,.
