Feeding, Anatomy and Digestive Enzymes of False Limpet Siphonaria Guamensis
World Journal of Fish and Marine Sciences 5 (1): 104-109, 2013 ISSN 2078-4589 © IDOSI Publications, 2013 DOI: 10.5829/idosi.wjfms.2013.05.01.66144 Feeding, Anatomy and Digestive Enzymes of False Limpet Siphonaria guamensis K.V.R. Murty, A. Shameem and K. Umadevi Department of Marine Living Resources Andhra University, Visakhapatnam 530 003, A.P., India Abstract: Very little information has been available in the literature on the feeding habits, anatomy and histology of digestive system of siphonariid limpets. The present study revealed Siphonaria guamensis feeds on the crustose red alga Hildenbrandia prototypus browsing on the rocks by rasping action of radula. The anatomy of digestive system of Siphonaria guamensis is similar with that of the other siphonariid limpets but the length of gut and colon are shorter than the patellogastropod limpets like Cellana radiata, patella vulgata, Fissurella barbadensis and species of Acmaea. The salivary glands are the main source of the enzyme system of Siphonaria guamensis. They contained enzymes which can act on carbohydrates, proteins and polysaccharides. The enzyme which can act on proteins was found only in salivary glands and not detected in any other part of the digestive system. No lypolytic activity was seen in any part of the digestive system of the animal.

Zoology Department, University of Cape Town. Patella Vulgata and P. Aspersa Are Attacked by Haematopus Ostralegus, P. Aspersa Be
THE RESPONSES OF SOUTH AFRICAN PATELLID LIMPETS TO INVERTEBRATE PREDATORS G M BRANCH Zoology Department, University of Cape Town. Accepted: February 1978 ABSTRACT The starfISh Marthasterias glacialis is a generalized predator, feeding particularly on Choromytillis meridiOflalis, but also on several limpets, notably Patella longicosta. T1Iais d"bia (Gastropoda) feeds mainly on barnacles, mussels, and Patella gran"laris. The gastropods BumUJH!na delalandii and B. cincta are principally scavengers, feeding on damaged or dead animals. The responses of Patella spp. to these predators are described. P. gran"laris. P. concolor. P. compressa and P. miniata all retreat rapidly on contact. Small P. grallQtina and P. oculus respond similarly, but larger specimens react aggressively, smashing their shells downwards and often damaging the predator. The territorial species (P.longicosta. P. coch/ear and P. tablilaris) all retreat to their scan and remain clamped there. P. argenvillei and P. tablilaris are usually unresponsive, possibly because they are too large to fall prey. Cellana capensis rolls its mantle upwards to cover the shell, preventing predators from attaching. The responses and their effectiveness are discussed in relation to other behavioural patterns displayed by limpets. There is no correlation between the intensity of a prey's response to a predator and the degree of contact . ) 0 between the two in the field. 1 0 2 d e INTRODUCTION t a d A variety of limpet predators has been recorded. Several birds attack limpets by knocking ( r them off the rock, and either picking out the flesh or consuming the whole limpet and e h s regurgitating the shell: oyster catchers (Haemlltopus spp.), various gulls (LaTUS spp.) and the i l b u sheathbill (Chionus alba) (Test 1945; Feare 1971; Walker 1972). -

Where Can We Find Limpets?
We See Sea Shells by the Seashore Where can we find limpets? Isabella and Evangeline Burns Introduction On holidays our family often goes to the town of Ulladulla on the New South Wales south coast. When we do we always visit the rock pools and rock platform. We always look forward to these trips. We look for pretty starfish and gooey limpets and dead, dried-out blue bottles that pop when we step on them. We enjoy these expeditions so much that we wanted to learn more about some of the animals that live on the rock platform. Many animals live on the rock platform. There are starfish, sea snails and crabs. We decided to look at limpets because they have a pretty shell with many different coloured stripes and the rock platform is covered in them. Also, limpets are well known for being very strong and very difficult to pull off the rocks. This was an animal worth knowing about. Aim We wanted to find out where on the rock platform limpets live. Do they live in the wet or the dry areas of the rock platform? 2 Background Research The animal we are looking at is called the Variegated Limpet. Its scientific name is Cellana tramoserica. It is found on the south-eastern coast of Australia from Queensland to South Australia. Source: www.mesa.edu.au Limpets are gastropods. This means that that they are like snails. They have oval shells shaped like a tent to protect their soft squishy body. The soft squishy part is called their foot! They also have gills to breathe underwater. -

Rocky Shore Snails As Material for Projects (With a Key for Their Identification)
Field Studies, 10, (2003) 601 - 634 ROCKY SHORE SNAILS AS MATERIAL FOR PROJECTS (WITH A KEY FOR THEIR IDENTIFICATION) J. H. CROTHERS Egypt Cottage, Fair Cross, Washford, Watchet, Somerset TA23 0LY ABSTRACT Rocky sea shores are amongst the best habitats in which to carry out biological field projects. In that habitat, marine snails (prosobranchs) offer the most opportunities for individual investigations, being easy to find, to identify, to count and to measure and beng sufficiently robust to survive the experience. A key is provided for the identification of the larger species and suggestions are made for investigations to exploit selected features of individual species. INTRODUCTION Rocky sea shores offer one of the best habitats for individual or group investigations. Not only is there de facto public access (once you have got there) but also the physical factors that dominate the environment - tides (inundation versus desiccation), waves, heat, cold, light, dark, salinity etc. - change significantly over a few metres in distance. As a bonus, most of the fauna and flora lives out on the open rock surface and patterns of distribution may be clearly visible to the naked eye. Finally, they are amongst the most ‘natural’ of habitats in the British Isles; unless there has been an oil spill, rocky sea shores are unlikely to have been greatly affected by covert human activity. Some 270 species of marine snail (Phylum Mollusca, Class Gastropoda; Sub-Class Prosobranchia) live in the seas around the British Isles (Graham, 1988) and their empty shells may be found on many beaches. Most of these species are small (less than 3 mm long) or live beneath the tidemarks. -

Limpets of the species Patella caerulea were collected between April 2016 and April 2017 from two sites, and two samplings per each site with varying degree of exposure to wave action and anthropogenic pressure, in Eastern Mediterranean (Pagasitikos Gulf, Central Greece). This study addresses a knowledge gap on population characteristics of P. caerulea populations in Eastern Mediterranean, assesses population structure, allometric relationships, and reproductive status. Morphometric characteristics exhibited spatio-temporal variation. Population density was significantly higher at the exposed site. Spatial relationship between members of the population exhibited clumped pattern of dispersion during spring. Broadcast spawning of the population occurred during summer. Seven dominant age groups were identified, with the dominant cohort in the third-year
