The green sea turtle (Chelonia mydas) has been a species of global concern for decades. In this study, heavy metals (mercury: Hg; Cadmium: Cd; Lead: Pb; Copper: Cu; and Zinc: Zn) were measured in blood and three egg fraction of green sea turtles nesting on the northern coast of Sea of Oman. Heavy metals concentrations in blood, yolk, albumen, and egg shell ranged between 0.16–36.78, 0.006–33.88, 0.003–4.02, and 0.002–6.85 μg/g (ww), respectively.

Sea turtles spend the majority of their immature and adult lives in foraging grounds, yet few studies have examined their abundance and condition in these areas when compared to more accessible nesting beach habitats. Here, a 5-year dive log, photo-identification (photo-ID) and surface encounter datasets were used to investigate the abundance, individual movements and distribution of sea turtles along 40 km of coastal reefs in southern Mozambique. A generalized linear model (GLM) was constructed with turtle sightings as the response variable.

Marine turtles are long-lived reptiles that appeared on Earth in the late Triassic. There are seven extant species worldwide, five of which can be found in the Red Sea: the green turtle, the hawksbill turtle, the loggerhead turtle, the olive ridley turtle and the leatherback turtle.

Vultures are a distinctive and important components of biodiversity. They also provide critical ecosystem services by cleaning up carcasses and other organic waste in the environment, which has huge ramifications in preventing the spread of diseases in both wild and domestic animals, and pathogenic risks to humans.

Including a management and monitoring system to conserve the species
