The individual positions of 200 intertidal chitons [Acanthopleura brevispinosa (Sowerby) and A. gemmata (Blainville)] were recorded throughout 55 low tides on a Somalian shore, using a discrete sampling method. Both species feed during nocturnal low tide and rest during the day and high tide. Due to this activity rhythm, individual positions recorded during diurnal and nocturnal low tides give information on the rest habits of the chitons and on their movements, respectively. The resting and… Expand

A Motographic Analysis of Foraging Behaviour in Intertidal Chitons (Acanthopleura Spp.)
TLDR
Due to different tidal and diel constraints on their activity the three species of Acanthopleura allocated different absolute time to foraging, but the fraction of time spent foraging relative to the total excursion was similar in each. Expand
Competition for the home and aggressive behaviour in the chiton Acanthopleura gemmata (Blainville) (Mollusca: Polyplacophora)
TLDR
The highly specialized resting habits clearly protects A. gemmata from its most important predator, the toad fish Arothron immaculatus, and the current hypotheses concerning the adaptive value of the homing behaviour in littoral molluscs are discussed. Expand
ECOLOGICAL DETERMINANTS OF BIOECONOMICS IN THREE INTERTIDAL CHITONS (ACANTHOPLEURA SPP.)
TLDR
The utmost importance of spatial parameters-and related modification in shelter availability and exposure to predators-in shaping the specific foraging behaviour has been revealed by a principal component analysis. Expand
The role of trail following in the homing of intertidal chitons: A comparison between threeAcanthopleura spp.
TLDR
Findings confirm that, despite the interspecific difference in ecology and the related variation in spatial organization of foraging excursions, trail following is the basic mechanism for homing in intertidal chitons. Expand
Trail following in the chiton Acanthopleura gemmata: operational and ecological problems
TLDR
The findings suggest that the trails released by A. gemmata are complex, including both quasi-individual and species-specific information, and this chiton may utilize its trail following capacity not only to home, but also for the retrieval of the feeding grounds night after night. Expand
Variation in foraging activity of Acanthochitona garnoti (Mollusca: Polyplacophora) from different habitats
TLDR
Chitons from upper-shore pools were active during both day and night low tides, and A. garnoti was found to have a ranging pattern of activity on boulder shores and a homing pattern on aeolian shores. Expand
Behavioural Responses to Crowding Modification and Home Intrusion in Acanthopleura gemmata (Mollusca, Polyplacophora)
TLDR
The intertidal chiton Acanthopleura gemmata (Blainville) is a central place forager which rests in a dug scar and moves at nocturnal low tide, but local overcrowding when body-contact is lacking also reduces activity. Expand
Eco-ethological aspects of homing behaviour in molluscs
TLDR
Both intertidal chitons and gastropods, and land pulmonates adopt movement patterns centred around a refuge where physical and biotic stress can be avoided and homing to a scar or to a permanent and personal home reduces dehydration during exposure to air and protects from predation. Expand
Theoretical analysis of rhythmical clustering in an intertidal gastropod
TLDR
A mathematical model of the intertidal snail Nerita textilis Gmelin is proposed, which takes into account the trail-following mechanism, the effect of cliff morphology and the semilunar rhythm, and the utility of the model in the estimation of parameter values is considered. Expand
Reproductive periodicity of the tropical intertidal chiton Acanthopleura gemmata at One Tree Island, Great Barrier Reef, near its southern latitudinal limit
TLDR
The reproductive pattern of A. gemmata at its southern limit is similar and 6 months out of phase to that reported for populations in the Gulf of Suez, at the northern limit of its distribution, which suggests that photoperiod may be an important factor in modulating reproduction. Expand

Movements of intertidal gastropods
TLDR
The model of movement was used to predict the effect of different percentage cover in small pools on the movement of A. constricta, which shows a preference for this micro-habitat, and increased availability of small pools reduced the mean distance moved by this species. Expand
Intertidal distribution and long-term movements of Littorina irrorata (Mollusca: Gastropoda)
TLDR
Despite a slight offshore movement during the fall and winter, the snails moved more parallel to the shoreline than perpendicular to it, and correlated with the presence of Spartina alterniflora and other plants in the upper intertidal zone. Expand
Field observations on the rhythmic behaviour of Nerita textilis (Gastropoda: Prosobranchia)
Field observations on Nerita textilis Dillwyn inhabiting rocky cliffs at Sar Uanle (Southern Somalia) revealed that during the resting phase some of the snails are scattered on the upper cliff andExpand
On the ecology of the Caribbean chitons Acanthopleura granulata Gmelin and Chiton tuberculatus Linné: density, mortality, feeding, reproduction, and growth
TLDR
Ecological studies on two tropical chiton species, including density, mortality, feeding, reproduction, and growth, were carried out along the shore on coral reefs in Puerto Rico and Panama. Expand
Behavioural adaptation of the gastropod Nerita polita L. on different shores at Aldabra Atoll

TLDR
The study showed that snails inhabiting different shores are behaviourally adapted to the actual morphology of the coast and its exposure to wave action. Expand
Foraging movements and homing in the limpet Patella vulgata L
TLDR
In two populations of Patella vulgata in the Isle of Man foraging activity is restricted to daytime high waters, with about 75 per cent of the population foraging on any one day, compared with that of the same species in Alderney, where foraging is limited to nocturnal low waters. Expand
The ecology of intertidal gastropods
TLDR
The chapter dwells on the competition and predation due to the distribution and abundance of population of intertidal gastropods, its reproductive biology, and the geographical distribution and influences of gastropod on the structure of interTidal communities. Expand
Studies on activity pattern of the patellid limpet Cellana toreuma (Reeve)
TLDR
Compared with a nocturnal limpet, C. nigrolineata (Reeve), the divergence in the behavioural patterns may be a function of the extent to which limpets are influenced by light. Expand
