Results of the Austrian-Indian Hydrobiological Mission 1976 to the Andaman-Islands: Part IV: the Freshwater Gastropods of the Andaman-Islands
©Naturhistorisches Museum Wien, download unter www.biologiezentrum.at Ann. Naturhist. Mus. Wien 86 B 145-204 Wien, November 1984 Results of the Austrian-Indian Hydrobiological Mission 1976 to the Andaman-Islands: Part IV: The Freshwater Gastropods of the Andaman-Islands By FERDINAND STARMÜHLNER ') Abstract The study deals with 20 species of Fresh- and Brackishwater Gastropods, collected by the Austrian-Indian Hydrobiological Mission 1976 on the Andaman-Islands (North- and South-Andaman) in the Gulf of Bengal. From every species, collected at 26 stations (20 at South-, and 6 at North- Andaman), mostly in running waters, are given conchological, anatomical, ecological-biological and zoogeographical remarks. In the General Part the distribution of the found species in the running waters between headwaters and mouth-region is shown. The zoogeographical position of the Freshwater Gastropods is characterized by the dominance of malayo-pacific elements.* 1. Introduction In contrast to the high increased literature concerning the Freshwater Gas- tropods of the Western Indian Ocean Islands (Madagascar and adjacent islands, Sri Lanka) for example: SGANZIN (1843); DESHAYES (1863); MORELET (1877, 1879, 1881 a & b, 1882 and 1883); CROSSE (1879, 1880, 1881); DOHRN (1857, 1858); BOETTGER (1889, 1890, 1892); MARTENS (1880 [in MOEBIUS]); MARTENS & WIEG- MANN (1898); SYKES (1905), GERMAIN (1921); CONOLLY (1925); DAUTZENBERG (1929); HUBENDICK (1951); GRÉBINE & MENACHÉ (1953); RANSON (1956); BARNACLE (1962); MENDIS & FERNANDO (1962); STARMÜHLNER (1969, 1974, 1983); FERNANDO (1969 and some others) particulars, concerning the Freshwater Gastropods of the Andaman- & Nicobar Islands are very rare: The stations, mostly from the Nicobars, are based on shell-collections such as from ROEPSTORFF, WARNEFORD and the Austrian NOVARA-Expedition 1857 to the Nicobars.

In 2007 and 2011 specimens of this species were obtained from two separate localities on the south coast of the island. Comparisons were made with von Martens’ original description, specimens from the Korean mainland, and illustrations and descriptions in the literature. Although there were some differences in color and markings, and slight differences in morphology, the specimens from Jeju Island compare well with those from the mainland and in the literature. The shells of this species become more ovate and more eroded with age. In one locality, a small river, specimens of the pleurocerid Semisulcospira libertina (Gould, 1859), were found adjacent to, and coexisting with, a population of C. retropictus, an association that often occurs. The occurrence of Clithon retropictus represents a range extension to Jeju Island.

Predation on Hardest Molluscan Eggs by Confamilial Snails (Neritidae) and Its Potential Significance in Egg-Laying Site Selection
PREDATION ON HARDEST MOLLUSCAN EGGS BY CONFAMILIAL SNAILS (NERITIDAE) AND ITS POTENTIAL SIGNIFICANCE IN EGG-LAYING SITE SELECTION YASUNORI KANO1 AND HIROAKI FUKUMORI1,2 1Department of Marine Ecosystems Dynamics, Atmosphere and Ocean Research Institute, The University of Tokyo, 5-1-5 Kashiwanoha, Kashiwa, Chiba 277-8564, Japan; and 2Graduate School of Agriculture, University of Miyazaki, 1-1 Gakuen-kibanadai-nishi, Miyazaki 889-2192, Japan Correspondence: Y. Kano; e-mail: [email protected] (Received 12 December 2009; accepted 14 May 2010) ABSTRACT Neritid snails (Gastropoda: Neritimorpha) protect their eggs in a hard capsule, of tough conchiolin, reinforced by mineral particles derived from the faeces and stored in a special sac near the anus and oviduct opening. Predation on this arguably hardest of molluscan egg capsule is described and illus- trated here; neritids of the freshwater to brackish-water genera Clithon and Vittina, generally classified Downloaded from as herbivores, feed facultatively on the eggs of various confamilial species after breaking the reinforced capsule lid by means of prolonged radular rasping. Intensive predation pressure by these common inhabitants in Indo-West Pacific coastal streams may have given rise to the remarkable egg-laying be- haviour of Neritina on the shells of other living snails. Our laboratory examination showed that Neritina species deposited clusters of egg capsules more frequently on the living shell than on other http://mollus.oxfordjournals.org/ substrates, and that the predation rate was significantly lower on this moving ‘nursery’. Predation rate was even lower on the small egg capsules of Clithon and Vittina themselves, which were deposited one by one in the depressions on the rough surfaces of stones.

Marine Gastropods (Gastropoda; Mollusca) Diversity and Distribution on Intertidal Rocky Shores of Terengganu, Peninsular Malaysia Nursalwa Baharuddin, Nurul B
Marine gastropods (Gastropoda; Mollusca) diversity and distribution on intertidal rocky shores of Terengganu, Peninsular Malaysia Nursalwa Baharuddin, Nurul B. Basri, Nurul H. Syawal School of Marine and Environmental Sciences, Malaysia Terengganu University, Kuala Nerus, Terengganu, Malaysia. Corresponding author: N. Baharuddin, [email protected] Abstract. Rocky shores are considered heterogenous environments due to their composition and structure. Therefore, they support numerous habitats of flora and fauna. Organisms found on rocky shores are facing intense physicochemical conditions during tidal changes from upper to lower intertidal zones. Gastropoda, or snails, belonging to the phylum Mollusca, have colonized highly contrasting habitats with single taxonomic orders represented in marine, freshwater, and terrestrial domains. To date, there is no documented evidence on the diversity of molluscan fauna found by intertidal rocky shores along the South China Sea in Peninsular Malaysia. This study determines the diversity and distribution of gastropods present along two intertidal rocky shores, Tanjung Jara and Teluk Bidara, in Dungun District, Terengganu, between November 2016 and February 2017. A total of five subclasses of gastropods (Caenogastropoda, Heterobranchia, Neritimorpha, Patellogastropoda and Vetigastropoda) belonging to nine families and 28 species were found from upper to lower intertidal zones. On Tanjung Jara, the upper zone was recorded to have the highest diversity and evenness indices (Shannon-Wiener diversity index: H’ = 0.702±0.213, and Pielou’s evenness index: J’ = 0.303±0.075) compared to the lower and middle zones. Planaxidae and Muricidae were the most predominant species found in all intertidal zones. In contrast, the lower zone in Teluk Bidara was recorded to have the highest diversity and evenness indices (Shannon-Wiener diversity index: H’ = 0.414±0.082, and Pielou’s evenness index: J’ = 0.269±0.028) compared to the upper and middle zones.

Riedel2 Keywords: tropical river, fluvial gastropods, ecology, distribution, ontogeny' protoconchs The tropical Matutinao River was investigated to snrdy factors determining the distribution of the extant gastropods. Since eco- logical zonation and life-cycles are somewhat correlated, we followed both research avenues and in particular focused on early ontogenetic strategies, discriminated by detailed studies of corresponding shell features. Twenty-six gastropod species, almost all of which are distributed over whole Cebu Island, occurred in the small Matutinao River. The specific associations of river sections, and ecological demands and life-cycles of gastropods are characterized. Of special interest are planktotrophic neritoi dean larvae, which are usually carried to the sea and develop in the marine environment, but in rare cases remain and success- fully metamorphose in freshwater. The biogeographic background and evolutionary consequences of the results are discussed.

Notes on the Stream Neritids ( Gastropoda; Prosobranchia) of Oceania
NOTES ON THE STREAM NERITIDS ( GASTROPODA; PROSOBRANCHIA) OF OCEANIA ALISON HAYNES School of Pure and Applied Sciences University of the South Pacific, P.O. Box 1168 Suva, Fiji Abstract-Five stream neritid genera Clithon, Neritilia, Neritodryas and Septaria inhabit Oceania. The simplest way to separate the genera is to examine the shape of their opercula. Variations in the shape, colour and markings of the shell tend to make identification of the species difficult. At least 33 species of freshwater neritids are found throughout Oceania. Apart from the four endemic spe cies from the Hawaiian islands, the species that inhabit Oceania are also found in South East Asia and New Guinea. Fifteen species have so far been reported from North Pacific islands and twenty nine species from South Pacific islands. Introduction The two most important prosobranch gastropod families that inhabit the rivers and streams of the Pacific islands are the Thiaridae and the Neritidae. In general the Thiaridae have long turret-shaped shells while the Neritidae have streamlined shells with a large body whorl. The Neritidae are usually found in fast flowing streams although a few spe cies inhabit the tidal regions at the mouth of rivers. Gastropods were collected from the streams of most Pacific island groups during the nineteenth century. These were described by Lamarck (1815/22), Reeve (1856), Mousson (1869, 1870) and Gassies (1863). More recent surveys of freshwater gastropods have been made on Guam (Raulerson, 1979), Palau (Bright & June, 1979), Hawaii (Maciolek, 1975), New Caledonia (Franc, 1956; Starmiihlner, 1976), Guadalcanal (Solomon Is.), Efate (Vanuatu), Tahiti (Starmiihlner, 1976) and Viti Levu (Fiji) (Starmiihlner, 1976; Haynes, 1985).
