Última A study on the Gut contents of live Juvenile Loggerhead Turtles, Caretta Caretta (Linnaeus) (Reptilia, Cheloniidae), from the South-Eastern part of the North Atlantic Ocean, with emphasis on Coelenterate Identification Naturalis Nierop, M.M. van; Hartog, J.C. den. The gut contents of five juvenile individuals of the loggerhead turtle Caretta caretta (L.) from waters around Madeira, Selvagem Grande (Selvagens Islands) and São Miguel (Azores) were analysed macro- and microscopically. Macroscopic investigations showed that epipelagic salps (e.g., Pyrosoma atlanticum Péron) and gastropods (e.g., Ianthina spp. and Pterotrachea spp.) constituted an important part of the food remains present in these loggerheads. To a lesser extent this also holds for organisms such as goose-barnacles (Lepas spp.). and Idotea metallica Bosc, which live on drifting materials, including algae. Microscopic examination revealed the presence in all turtles of large numbers of nematocysts, deriving mainly from Siphonophora and to a lesser extent...

Ano: 1984 URL: http://www.repository.naturalis.nl/record/319311 A study on the Gut contents of six Leathery Turtles Dermochelys Coriacea (Linnaeus) (Reptilia: Testudines: Dermochelyidae) from British waters and from the Netherlands Naturalis Hartog, J.C. den; Nierop, M.M. van. Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have...
