Underwater with Sri Lanka's sperm whales – in pictures

The sperm whale may be one of the most successful animals in the ocean, boasting a global distribution that survived the toll of the 20th century, when whaling factory fleets took three million gre

Public Awareness Program and Development of Education Toolkit for Green Sea Turtle Conservation in Sarawak, Malaysia

Nobody knows exactly what happened during "the lost years" of the turtles in the wild, thus a green turtle headstarting project was carried out at Pantai Pandan, Lundu, Sarawak, Malaysia from June 2014 until December 2015 to shed some lights on the growth of hatchlings during a small part of their "lost years". As a consequent, opportunity of small scale awareness campaigns on sea turtle conservation arises during this project. Activities include talk related to green turtles conservation, hands on experience on turtle-human interaction (supervised), and documentation via videography.

Using Photographic Identification To Monitor Sea Turtle Populations At Perhentian Islands Marine Park In Malaysia

Perhentian Islands Marine Park is home to foraging and nesting Green Turtles (Chelonia mydas) and Hawksbill Turtles (Eretmochelys imbricata) but little information is available other than nesting trends and hatching success. We used photographic identification (photo-ID) methods to identify individuals and to determine their sex ratios, habitat use, and site fidelity.

Low Genetic Diversity after a Bottleneck in a Population of a Critically Endangered Migratory Marine Turtle Species.

Hawksbill turtles (Eretmochelys imbricata), which are distributed throughout the world's oceans, have undergone drastic declines across their range, largely due to anthropogenic factors. Assessing sizes, genetic variability and structure of their populations at global and regional levels is critical to the development of conservation management strategies.

Evaluating the Threat of IUU Fishing to Sea Turtles in the Indian Ocean and Southeast Asia using Expert Elicitation

Illegal, unreported and unregulated (IUU) fishing is a pervasive issue that affects economic, social, regulatory and environmental systems in all ocean basins. Research on the ecological impacts of IUU fishing has been relatively underrepresented, with minimal investigation into how IUU fishing may negatively affect populations of marine megafauna, such as sea turtles.

Hatching success of Hawksbill sea turtles (Eretmochelys imbricata) in a protected hatchery site in Nakhiloo Island, Persian Gulf

Hawksbill sea turtle is one of the two important marine turtles, breeding and nesting regularly in the Iran beaches of the Persian Gulf. Hawksbill turtles are critically endangered and there is very little information regarding their Indian Northwest population. Thirty eight nests of Eretmochelys imbricata were monitored during the nesting season in Nakhiloo Island. Half of the nests were transferred into a protected hatchery site, in which there were no risk of predation and high-tide inundation. All nests were closely monitored during the incubation period.

Diversity, Habitat Distribution, and Indigenous Hunting of Marine Turtles in the Calamian Islands, Palawan, Republic of the Philippines

All of the world’s seven species of marine turtle are threatened by a multitude of anthropogenic pressures across all stages of their life history. The Calamian Islands, Palawan, Philippines provide important foraging and nesting grounds for four species: green turtles (Chelonia mydas), hawksbill turtles (Eretmochelys imbricata), loggerheads (Caretta caretta), and leatherbacks (Dermochelys coriacea).

Genetic Structure and Diversity of Green Sea Turtle (Chelonia mydas) from South China Sea inferred by mtDNA control region sequence

We analyzed 88 control region sequences of green sea turtle (Chelonia mydas) from around Hainan Island in the South China Sea. These sequences had a length of 489 bp and revealed 8 mtDNA haplotypes of which four haplotypes (CMC1, CMC4, CMC7, and CMC8) had not been discovered before. Haplotype diversity (h) and nucleotide diversity (π) were 0.45 ± 0.054 and 0.0035 ± 0.0014, respectively. Neighbor-Joining tree based on control region sequences revealed that genetic relationship between green sea turtles from the South China Sea and from Japan Sea were very close.

Indian man's fight to save whale sharks

Whale sharks are the world's largest fish, and are classified as endangered. In India, their survival has been put at risk by hunting or being caught in fishing nets.
