| Abstract | To understand the effects of predation by gastropods on juveniles of the Japanese spiny turban snail Turbo cornutus, a field survey and laboratory experiments were conducted. The species compositions of the order Neogastropoda inside turfs of articulated coralline algae (ACA) on the east coast of Sagami Bay were surveyed monthly, and the dominant species inside the ACA turfs were identified. Laboratory experiments were conducted to examine the effects of predation by the dominant neogastropods on small gastropods in ACA turfs. Turban snails, which inhabit ACA turfs during their juvenile stages, were predated by two muricid gastropods, Ergalatax contractus and Thais bronni, with the predation rate of E. contractus being significantly higher than that of T. bronni. While E. contractus could also predate two other species of gastropods, Anachis misera and Cantharidus japonicus, the predation rates on these two snails were significantly lower than on T. cornutus. The observed defensive behaviors were different among the three prey species, and the defensive strategy related to the calcified operculum of T. cornutus was not efficient against predation by E. contractus. It is concluded that the predation by E. contractus represents an important factor in the mortality of juvenile turban snails inside ACA turfs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
