The detailed description Muricanthus kuesterianus of this species has been given with the comparison of its close resembled species Chicoreus virgineus Chicoreus virgineus. INTRODUCTION Muricidae, the largest and varied taxonomic family among marine gastropods has small to large predatory sea snails in the Order Neogastropoda. At least 1,000 species of muricids under numerous subfamilies are known. Many muricids have unusual shells which are considered attractive by shell collectors. The spire and body whorl of the muricids are often ornamental with knobs, tubercules, ribbing or spines. Muricids have episodic growth which means that the shell grows in spurts, remain- ing in the same size for a while before rapidly growing to the next size stage resulting in a series of varices on each whorl. Most species of muricids are carnivorous, feeding on other gastropods, bivalves and barnacles. In March 2007, during the course of faunistic surveys along the Palk Strait region of southeast coast of India (Fig.

Universidad de Oriente, Núcleo de Sucre. Departamento de Química, Escuela de Ciencias, Cumaná, Estado Sucre 1601, Venezuela; [email protected] 2. Instituto Universitario de Tecnología, Cumaná, Estado Sucre 1601, Venezuela. * Correspondencia. Recibido 10-VII-2009. Corregido 25-X-2009. Aceptado 27-XI-2009. Abstract: Fatty acids composition of the marine snails Phyllonotus pomum and Chicoreus brevifrons (Muricidae). Muricid species of P. pomum and C. brevifrons are of economic importance in the Caribbean. This study includes a comparative evaluation of fatty acid content in the total lipid composition of Phyllonotus pomum and Chicoreus brevifrons. Snail samples were collected during the rainy, dry and transition seasons, in Punta Arena, Sucre (Venezuela). Total lipids were extracted and the specific fatty acid contents were analyzed by gas chromatography. Lipid concentrations varied between 0.87 and 1.85%, with minimum and maximum values corresponding to C. brevifrons collected during rainy and dry seasons, respectively. In the case of total lipids, a high concentration of unsaturated fatty acids (57.21-70.05%) was observed followed by saturated fatty acids (20.33-31.94%), during all seasons. The polyunsaturated occurred in higher proportion among the unsaturated fatty acids, except for P. pomum which showed higher proportion of monounsaturated fatty acids (38.95%) dur- ing the transition season. The prevailing fatty acids were: C14:0, C16:0, C18:0, C20:1, C22:1 ω-11, C22:1 ω-9, C18:3 ω-3, C20:5 ω-3 and C22:6 ω-3, among which docosahexaenoic acid was the predominant polyunsaturated fatty acid, showing values between 4.62 and 33.11%.

  • Nature in the Parasha Parashat Tetzaveh – the Mystical Turquoise
    בס”ד Nature in the Parasha By Rebbetzin Chana Bracha Siegelbaum Parashat Tetzaveh – The Mystical Turquoise Colored Snail Fish This week’s parasha centers around the garments of the Kohanim when serving in the Mishkan (Tabernacle). The exquisite fabric of the garments were woven together from linen, gold and wool dyed in three vibrant colors: tola’at shani (crimson), argaman (purple) and lastly techelet (sky-blue). These colors were produced by different animals or plants. Naturally, it is disputed which animals or plants produce each of these colors. Even the nature of each of the colors is disputed, and my translation is only one possibility. Until recently, I thought that the tola’at shani color was dyed from worms as the Hebrew word tola’at means worm. However, Rambam explains that tola’at shani is not produced from a worm, but from a vegetable product in which a worm grows (Hilchot Parah Adumah 3:2). There is even greater dispute among the sages until this day about the nature of the creature that produces my favorite color: techelet. For as long as I can remember, I have always been attracted to this deep mysterious color that reminds us of the color of the sky just before the sun sets. I feel energized in my element when I wear techelet, and as those of you who know me can testify, I wear it most often, to the extent that some of you even call me the ‘the turquoise Rebbetzin.’ Techelet, the ancient biblical sky-blue dye, which adorned the robes of kings, priests, and simple Jews, was lost to the world nearly 1300 years ago.

  • CONE SHELLS - CONIDAE MNHN Koumac 2018
    Living Seashells of the Tropical Indo-Pacific Photographic guide with 1500+ species covered Andrey Ryanskiy INTRODUCTION, COPYRIGHT, ACKNOWLEDGMENTS INTRODUCTION Seashell or sea shells are the hard exoskeleton of mollusks such as snails, clams, chitons. For most people, acquaintance with mollusks began with empty shells. These shells often delight the eye with a variety of shapes and colors. Conchology studies the mollusk shells and this science dates back to the 17th century. However, modern science - malacology is the study of mollusks as whole organisms. Today more and more people are interacting with ocean - divers, snorkelers, beach goers - all of them often find in the seas not empty shells, but live mollusks - living shells, whose appearance is significantly different from museum specimens. This book serves as a tool for identifying such animals. The book covers the region from the Red Sea to Hawaii, Marshall Islands and Guam. Inside the book: • Photographs of 1500+ species, including one hundred cowries (Cypraeidae) and more than one hundred twenty allied cowries (Ovulidae) of the region; • Live photo of hundreds of species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book ACKNOWLEDGMENTS The significant part of photographs in this book were made by Jeanette Johnson and Scott Johnson during the decades of diving and exploring the beautiful reefs of Indo-Pacific from Indonesia and Philippines to Hawaii and Solomons. They provided to readers not only the great photos but also in-depth knowledge of the fascinating world of living seashells. Sincere thanks to Philippe Bouchet, National Museum of Natural History (Paris), for inviting the author to participate in the La Planete Revisitee expedition program and permission to use some of the NMNH photos.

  • The History of the Sacred Purple: the Use of Muricidae As a Dye Source
    The Discovery of Purple by Theodoor van Thulden (1606-1669), painted 1636-1638, oil. The History of the Sacred Purple: The Use of Muricidae as a Dye Source By Her Ladyship Claire le Deyare Barony of Dragon’s Mist, Kingdom of An Tir [email protected] 1 Introduction When mentioning the color of purple cloth to someone in a historical context, all sorts of misconceptions come into play. Some refer to the color as royal purple, or Tyrian purple. Some people say it refers to a certain shade, rather than the whole color pallet. Others will tell you that it is the color of kings and that no one else can wear the color. All of these statements are both true, and untrue at the same time. The intent of this research paper is to help correct those misconceptions, as well as to give background and insight into what is arguably the world’s most famous and least understood dye. Historically, the word purple referred not to a particular shade of dye, but rather a family of dye colors that came from one particular type of animal, the marine snail Murex, commonly known as the rock snail (Cardon, 2007). The epicenter of their use, and where they are most famous, is the Mediterranean. But there are also other species that were historically used in China, Japan, Mexico, and parts of Central and South America (see Figure 1. Baker, 1974). Many species of molluscs in the family Muricidae are used for dye, there are now different genus names besides Murex used for the snails that were historically used for dye (Cardon, 2007).
