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. -

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.

Arularasan*, K. Kesavan and P. S. Lyla CAS in Marine Biology, Faculty of Marine Sciences, Annamalai University, Parangipettai, India ______________________________________________________________________________ ABSTRACT The radula has been recogonised as an important morphological criterion for the taxonomic allocation of species. The radula in general vary within a subclass that of prosobranch gastropods. The scanning Electron microscope (SEM) is one of the powerful tool in the studies of radula. In the present study the structural morphology of Strombus canarium radula were photographed on an scanning Electron microscope. The radula of S. canarium is typically of taenioglossate type with one median tooth flanked by one pair of lateral tooth and two pairs of marginals on each side (7 teeth per row). The lateral tooth is hook-shaped and curved inwards towards the central tooth. In taenioglossan snails, the radular formula is 2+1+1+1+2. The length of the radular ribbon measured 18 mm in S. canarium. The radula consists of seven teeth in each row, but each of these teeth has a distinctive shape and a specific number of tiny cusps on edges. The tooth in the centre is called center teeth or rachidian (R) teeth. Beyond each lateral, there is an inner marginal and outer marginal. It is obviously observed in the radula of herbivorous animals. Keywords: gastropod, radula, taenioglossan, Strombus canarium, SEM. -

But there were some apparent differences. In M.kuesterianus rachidian tooth have a broad base than that of Muricanthus virgineus. The base of the median cusp was broad, short, stout and pointed straight towards the anterior end.The left lateral cusp elongated, sharp, slightly bent and pointed outwards and the right lateral cusp dorso ventrally flattened and the anterior end small, slightly pointed. In between the median and left lateral cusps, a sharp and pointed denticle is present where as the right laterals and median cups there is no denticle. The lateral teeth which are two in numbers flanked median rachidian. Keywords: Scanning Electron Microscope, Radula, Gastropoda, Muricidae, Muricanthus kuesteianus. Resumen Los estudios de miscroscopía electrónica de transmisión (SEM) revelaron que la rádula de Muricanthus kuesterianus se asemejan a M. virgineus en varios detalles. Pero hubo algunas diferencias aparentes. En el diente raquídeo de M. kuesterianus se encontró una base más ancha que M. virgineus. La base de la cúspide media fue ancha, corta, robusta y punteada y apuntado directamente hacia el extremo anterior. -

Using Palk bay Peterson’s method, male of Chicoreus virgineus was found to attain a maximum length of 7.25cm and the female a length of 10.2cm in the 4th year. In Muricanthus virgineus male and female attained a length of 8.5cm and 11.4cm respectively in 4th year. The results of probability plot method revealed that the male of Chicoreus virgineus reached a maximum length of 8.55cm, and the female 10.35cm in the 4th year. However, in Muricanthus virgineus, the maximum length of 9.4cm in male and 11.00cm in female were found in 4th year. Using Von Bertalanffy’s equation, Chicoreus virgineus male was found to attain a length of 8.85cm, and the female a length of 10.35cm while the male of Muricanthus virgineus calculated as 9.4cm, and the female 11.00cm of lengths in 4th year. -

The aim of the present study was to describe the radula of 2 Pugilina cochlidium populations using SEM. The radula in 2 species proves itself as a rachiglossate type showing the radular formula of 1 + R + 1. The first population hasthe central tooth wide with sharp cusps equal in length, emanate from posterior margin of tooth base. The lateral teeth have 2 cusps and are long, sharp, pointed and bent towards the rachidian tooth. Whereas the second population, the central tooth is narrow with sharp cusps equal in length, emanate from posterior margin of tooth base.

Emmanuel Joshua Jebasingh and R.P. Rajesh Suganthi Devadason Marine Research Institute, 44-Beach Road, Tuticorin-628 001, Tamilnadu, India *[email protected] Abstract The females of marine gastropod Babylonia spirata along Chennai Royapuram Fishing Harbour and Tuticorin coast showed reproductive anomaly i.e. superimposition of male sexual characters, imposex. Imposex frequency (93.8%) and the percentage of females with stage 4 of imposex (18.8%) were higher in Chennai than Tuticorin. However, no marked difference in male: female sex ratio was observed in Tuticorin (1.2: 1) and Chennai (0.9: 1). A further morphological change in the form of double penis in a female was observed in Tuticorin. Vas Deferens Sequence Index (VDS) in Tuticorin and Chenhai Royapuram Fishing Harbour (1.7 and 1.8) were well below the critical index value of 4. No occlusion of genital pore \;as observed. This reproductive anomaly could be linked to Tributyltin (TBT) leaching from antifouling paints used in fishing boats and ships along these coasts. Keywords: Gastropod Babylonia spirata, imposex Introduction The process of adsorption, colonization and develop- fouling paints was adversely impacting a number of non- ment of living and nonliving material on an immersed target marine organisms.

The Recent Mollusks: Gastropoda, Strom- bacea, Tonnacea, and Cymatiacea BY WILLIAM K. EMERSON' AND WILLIAM E. OLD, JR.2 INTRODUCTION The present paper continues a study of the Recent marine mollusks collected in west Mexican waters during the course of the expedition. The first report considered the family Conidae (Emerson and Old, 1962); the second report covered the superfamily Cypraeacea (Emerson and Old, 1963b). The present report treats the superfamilies Strombacea, Tonnacea, and Cymatiacea. Other reports are in progress. Specimens were taken by shore and intertidal collecting, by skin div- ing, and by dredging from a small skiff and from the schooner "Puritan." Dredging operations were restricted to depths no greater than 50 fath- oms. The itinerary and descriptions of the collecting stations were re- corded in the General Account of the expedition (Emerson, 1958). All the known species of the Strombacea and Tonnacea from the east- ern Pacific are represented in the present collection.

The correlation coefficient of the two species was found to be significant (P < 0.001). Significant difference was observed in the analysis of variance for various morphological measurements in males and females of Muricanthus virgineus. Highly significant results were also obtained for both the species in allometry and its correlation coefficient. INTRODUCTION The family Muricidae revealed that the existence of some species is already known to occur in the geographical area of the south east coast of India. Generally, the animals were collected from the local fisherman who had trawled them off the coastal area of Cuddalore coast. The economic impor- tance of these two species can hardly be emphasized from the stand point of food and medicinal, and cosmetic properties have been of tremendous importance to humans. The -
