- W8307801 abstract "Natural diet and spatial distribution of six species ofnPortunidae (Crustacea : Brachyura) were studied in severalninter-tidal areas in Moreton Bay, Queensland. Thesenspecies, Portunus pelagicus (Linnaeus), Charybdis hellerin(A. Milne-Edwards), Thalamita admete (Herbst), T. crenatan(H. Milne-Edwards), T. danae (Stimpson) and T- Siman(H. Milne-Edwards), overlap little with respect to spatialndistribution except in the case of T. admete and T. danae. T. admete, however, is usually considerably smaller thannT. danae. All these portunid species are omnivorous inndiet except for P. pelagicus which is a carnivore, andnall eat a wide range of living or freshly-killed slow-movingnor sessile food organisms. Spatial partitioningnof the environment, overlap of food requirements, temporalnseparation of activity and size segregation of species arendiscussed in relation to sympatry within inter-tidal portunidncrabs in Moreton Bay.n Diets of P. pelagicus, T. crenata, T. danae and T. simanare largely unaffected by their size, sex, and reproductivenstate but they vary considerably according to local availabilitynof food and their molt cycle stage. That diet doesnnot change as crabs grow is attributed to diversity among suitablenfood organisms in Moreton Say.n During feeding crabs usually crush gastropod and bivalve shellsnto obtain the soft fleshy parts although Scylla serrata opensnsome large bivalves without crushing the shell valves. Innthe case of predation on other crabs, legs and chelae of thenprey are removed before it is eaten.n In Portunus pelaqicus, feeding behaviour is aroused bynchemical odour, followed by directional location of foodninvolving simultaneous comparison on stimuli on right andnleft sides and ohemotactile location and identification ofnfood by the mouthparts and dactyls of the walking legs.nP. pelagicus detects some chemical constituents of food,nparticularly those which occur in greatest concentration innits own tissues and that of its prey at very low concentrations.nChemosensory organs in P. pelagicus are situated on the antennaenand antennules (distance receptors) , and the mouthparts andndactyls of the second to fifth pereipods (contact receptors).n" @default.
