An investigation on the predation mechanism of Chicoreus capucinus against Cerithidea cingulata, was done in July - December 2010. The study is descriptive and aims to determine the predation mechanism and prey perception distance. Research conducted at the aquarium and using 27 snails of Chicoreus capucinus for the predation mechanism experiment and 9 snails of Chicoreus capucinus for the prey perception distance experiment. The research was conducted by observing the behavior and mechanism of predation by Chicoreus capucinus, and calculate the length of time by detecting and approaching prey Chicoreus capucinus. The results of predation mechanism are 11 of snails Chicoreus capucinus feeding from the aperture’s prey, 9 of snails of Chicoreus capucinus bored the shell’s prey, and 3 snails of Chicoreus capucinus bored the operculum’s prey. Average total time for Chicoreus capucinus to be able to detect prey is 7 minutes 20 seconds. The Chicoreus capucinus sized Y (5--6 cm) had the fastest time to detect prey, whereas Chicoreus capucinus sized Z (6 --7 cm) had the longest time to detect prey. The average time to approach prey of Chicoreus capucinus was 25 minutes 58 seconds. The Chicoreus capucinus sized Y (5--6 cm) had the fastest time of approaching prey, whereas Chicoreus capucinus sized Z (6--7 cm) had the longest time approaching prey.

Seasonal status and movement of Pirenella cingulata according to habitat change studied from mangroves of Ghogha coast from December 2014 to November 2015. The maximum density (4.4/m2 area) of Pirenella cingulata reported during winter and lowest during monsoon (0.20/ m2 area). This mud snail was observed dependent on the mangrove during adverse climatic conditions during summer and monsoon seasons. Temperature and dissolved oxygen levels influence the density of P. cingulata. Keywords: Pirenella cingulata, Mangroves, Seasonal Conditions, Ghogha Coast INTRODUCTION Indo-West Pacific oceans are popular for the molluscan diversity, but despite more than two centuries of malacology, the basic knowledge about mangrove associated biota is still inadequate (Kiat, 2009). The mangroves are not only trees but itself an ecosystem comprises associated fauna, the biotope surrounded by the trees extensions like soil, stem, substrate, shade, tidal range etc., and are influential to the distribution of malacofauna (Lozouet and Plaziat, 2008). Indian coastline comprises three gulfs, namely Gulf of Kachchh and Gulf of Khambhat in west site while Gulf of Mannar in southeast side.

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.

China Abstract.- The effect of saltmarsh cordgrass, Spartina alterniflora (Poales: Poaceae) invasion stage on Cerithidea cingulata (Caenogastropoda: Potamididae) distribution was studied in 2007 at the eastern tidal flat of Lingkun Island, Wenzhou Bay, China. The distribution pattern of C. cingulata was aggregated during each season, as shown in experiments utilizing Taylor's power regression and Iowa's patchiness regression methods (P < 0.001). Two- way ANOVA indicated that densities were significantly affected by S. alterniflora invasion stage (P < 0.001), however, no significant season effect was found (P = 0.090) and on the interaction between the seasons (P = 0.939). The density distribution during the invasion stage was significantly different in each season as shown in one-way ANOVA. Pearson’s correlation coefficient analysis of density data indicated that the highest densities occurred in habitats at the initial invasion stage during summer. The peak in C. cingulata density during spring, autumn and winter occurred in habitats where invasion was classified as initial, whereas the lowest densities occurred in the stage of invasion completed during each season.

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.

  • Use of Antifouling Paints on Ship Hulls Over Past Four Decades and Consequent Imposex: a Review
    International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Index Copernicus Value (2013): 6.14 | Impact Factor (2013): 4.438 Use of Antifouling Paints on Ship Hulls over Past Four Decades and Consequent Imposex: A Review Nuzhat Afsar Assistant Professor, Institute of Marine Science, University of Karachi, Karachi-75270, Pakistan Abstract: Review provides the historic stance, general overview of gastropod populations being served as biosensors and developments in imposex detection. Typically muricoid species belonging to genus Nucella and Thais have been found to be good bioindicators globally. Although up to seven (7) imposex developmental stages have been described based on organotin accumulation by an organism and resultant morphological expression (penis and vas deferens development in females) due to endocrine disruption and steroidal imbalance. From Pakistan phenomenon of imposex has been described in nine (9) species of meso and neogasrtropods. Imposex stages 1-4 and 4+ have been found in examined muricids, bursid and buccinid species which revealed the moderate contamination effects on gastropod populations found along the Pakistan coast. Some archaeogastropods from Japan and Pakistan have also been tested respectively for reproductive fitness due to possible contamination effects. Keywords: shipping traffic, antifouling paints, gastropods, endocrine disruption 1. Introduction The application of TBT based antifouling paints was banned in the late 1980s in many countries. Legislation The phenomenon of imposex in gastropod species is have been implemented to restrict the use of TBT in anti globally recognized as a cheap, easily applied biological fouling paints [15-16] then finally a global ban on the use indicator test and marine gastropod species being served as of TBT from 2003 to 2008 was imposed by the biosensors have provided a guideline in assigning International Maritime Organization (IMO) to restrict and priorities for more rigorous chemical analysis and to remove all existing coatings from ship hulls [17].

Present address: The Kyoto University Museum, Yoshida Honmachi, Sakyo-ku, Kyoto 606-8501, Japan (email: [email protected]) Received December 19, 2005; Revised manuscript accepted May 26, 2006 Abstract. Cerithiform gastropods possess high-spired shells with small apertures, anterior canals or si- nuses, and usually one or more spiral rows of tubercles, spines or nodes. This shell morphology occurs mostly within the superfamily Cerithioidea. Several morphologic characters of cerithiform shells are adap- tive within five broad functional areas: (1) defence from shell-peeling predators (external sculpture, pre- adult internal barriers, preadult varices, adult aperture) (2) burrowing and infaunal life (burrowing sculp- tures, bent and elongated inhalant adult siphon, plough-like adult outer lip, flattened dorsal region of last whorl), (3) clamping of the aperture onto a solid substrate (broad tangential adult aperture), (4) stabilisa- tion of the shell when epifaunal (broad adult outer lip and at least three types of swellings located on the left ventrolateral side of the last whorl in the adult stage), and (5) righting after accidental overturning (pro- jecting dorsal tubercles or varix on the last or penultimate whorl, in one instance accompanied by hollow ventral tubercles that are removed by abrasion against the substrate in the adult stage). Most of these char- acters are made feasible by determinate growth and a countdown ontogenetic programme.
