Marine debris ingestion by Chelonia mydas (Testudines: Cheloniidae) on the Brazilian coast

Marine Pollution Bulletin, 2015
Chelonia mydas is distributed in several regions of the world and they are common in coastal regions and around islands. Between August 2008 and July 2009, 20 specimens of C. mydas were found dead on the beaches of Ubatuba, São Paulo, Brazil. The stomachs were removed and anthropogenic wastes were separated according their malleability and color.

Autumn Sightings of Marine Turtles (Cheloniidae) off South Texas

The Southwestern Naturalist, 1983
Based on sightings during low-altitude aerial surveys, 21-30 September 1979, the total number of marine turtles off South Texas-Aransas to Brownsville, inland coast to 18 m contour-was estimated conservatively as 19.0 ? .6. Turtles seen were probably loggerheads or Kemp's ridleys. One large turtle was seen in Laguna Madre adjacent to Mansfield Cut. All

Swimming in Sea Turtles of the Family Cheloniidae

Copeia, 1971
Cheloniid turtles swim by moving the blade of their pectoral flipper up and down along a line inclined from 40? to 70? from the horizontal plane. The leading edge of the blade is inclined anteroventrally on the downstroke and anterodorsally on the upstroke, and the tip of the blade usually inscribes a figure 8.

Electrophoretic characterization of a hybrid between Eretmochelys imbricata and Caretta caretta (Cheloniidae)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1990
Abstract 1. 1. An intermediate morphotype between Eretmochelys imbricata and Caretta caretta was studied in Praia do Forte, Bahia, Brazil. 2. 2. Three enzymatic systems were successfully analyzed: SOD, lactate dehydrogenase (LDH) and esterase (EST). Isoelectric focusing of total soluble proteins of muscle and transferrin were shown. 3.

Ovarian follicular development in the hawksbill turtle (Cheloniidae: Eretmochelys imbricata L.)

Journal of Morphology, 2012
AbstractOvarian follicular development is an essential process in the determination of maturation stages associated with size. This association acquires importance when managing populations of threatened species. We histologically processed 11 prepubescent ovaries, four pubescent ovaries, and one breeding adult ovary with vitellogenic follicles using ...

International migrations of South American sea turtles (Cheloniidae and Dermochelidae)

Animal Behaviour, 1973
Abstract Three species of sea turtles (the leatherback, Dermochelys coriacea ; the green turtle, Chelonia mydas ; and the olive ridley, Lepidochelys olivacea ) nest abundantly in the Guianas, especially on the beaches adjacent to the mouth of the Marowijne River. Tagging demonstrated that green turtles nesting in Surinam are recruited from feeding

Helminth Parasites of Juvenile Green TurtlesChelonia mydas(Testudines: Cheloniidae) in Brazil

Journal of Parasitology, 2015
The present study offers a parasitological analysis of juvenile individuals of the green turtle ( Chelonia mydas ) found on the Brazilian coast between 2004 and 2011. Helminths were found in 90 out of 136 individuals (66.2%, CI = 57.7-74.0).

Helminth Parasites of the Juvenile Hawksbill TurtleEretmochelys imbricata(Testudines: Cheloniidae) in Brazil

Journal of Parasitology, 2015
The helminth fauna of 31 juvenile specimens of Eretmochelys imbricata from the Brazilian coast was examined. Seventeen individuals were infected with helminths (54.8%). The helminths found were: Diaschistorchis pandus, Cricocephalus albus, Metacetabulum invaginatum, Pronocephalus obliquus (Pronocephalidae), Cymatocarpus solearis (Brachycoeliidae ...
