Hawksbills turtle – Extinction risk: Critically Endangered

© Jürgen Freund / WWF-Canon

Hawksbills are named for their narrow, pointed beak. They also have a distinctive pattern of overlapping scales on their shells that form a serrated-look on the edges. These colored and patterned shells make them highly-valuable and commonly sold as “tortoiseshell” in markets.

Hawksbills are found mainly throughout the world’s tropical oceans, predominantly in coral reefs. They feed mainly on sponges by using their narrow pointed beaks to extract them from crevices on the reef, but also eat sea anemones and jellyfish. Sea turtles are the living representatives of a group of reptiles that has existed on Earth and travelled our seas for the last 100 million years. They are a fundamental link in marine ecosystems and help maintain the health of coral reefs and sea grass beds.

WHY THEY MATTER
Hawksbills help maintain the health of coral reefs. As they remove prey such as sponges from the reef’s surface, they provide better access for reef fish to feed.  They also have cultural significance and tourism value.  For example, for local residents in the Coral Triangle, the flow of visitors who come to admire turtles is a vital source of income.

THREATS
Like other sea turtles, hawksbills are threatened by the loss of nesting and feeding habitats, excessive egg collection, fishery-related mortality, pollution, and coastal development. However, they are most threatened by wildlife trade.

ILLEGAL WILDLIFE TRADE
Despite their current protection under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and many national laws, there is still a disturbingly large amount of illegal trade in hawksbill shells and products. They are much sought after throughout the tropics for their beautiful brown and yellow carapace plates that are manufactured into tortoiseshell items for jewelry and ornaments. In recent decades, eastern Asia has provided an eager market for tortoiseshell.

WHAT WWF IS DOING

ADDRESSING WILDLIFE TRADE
WWF works with communities to reduce turtle harvesting and local trade in the Coral Triangle. In Malaysia, we help raise awareness about the threats hawksbills face and communicate the importance of protecting them. Exploitation  of  turtles is often driven by a lack of economic choices so WWF works to develop alternative livelihoods so that local people are no longer dependent on turtle products for income. WWF also works to stop the illegal trade of hawksbill products around the world through TRAFFIC, the wildlife trade monitoring network. We also train and equip local rangers to protect turtles from poaching and patrol nesting beaches.

ELIMINATING BYCATCH
WWF aims to reduce turtle bycatch by working with fisheries to switch to more turtle-friendly fishing hooks (“circle” hooks) and advocates for the use of special turtle excluder devices in nets. We run an international competition, known as Smart Gear, to attract creative new ways to solve bycatch problems and advance the best of those ideas. Winning devices have been designed to minimize the bycatch of turtles on tuna longlines and help turtles avoid gillnets. We track turtle movements using satellite to help prevent future interactions between fisheries and turtles. And we work with fishermen to save turtles caught in fishing gear.

PROTECTING SEA TURTLE HABITAT
WWF  works  around  the  world  to  establish  marine protected  areas (MPA)  to  ensure sea turtles have a safe place to nest, feed and migrate freely.  We encourage governments to strengthen legislation and provide funding for sea turtle protection. WWF  also supports  the  monitoring  and  patrolling  of  turtle nests  in  many  parts  of  the  world to equip local turtle conservationists. This often leads to ecotourism opportunities and offers alternative livelihoods.

SATELLITE TRACKING
Satellite telemetry allows researchers to track sea turtles as they swim from place to place. These satellite tags do not harm the turtles in any way and are designed to eventually fall off. The data will tell us where important feeding areas are, help us understand migration patterns, and anticipate where turtles may come in contact with fisheries and their gear.

My Reflection

My Reflection

This site is a tribute to Buddhism. Buddhism has given me a tremendous inspiration to be who and where I am today. Although I came to America at a very young age, however, I never once forget who I am and where I came from. One thing I know for sure is I was born as a Buddhist, live as a Buddhist and will leave this earth as a Buddhist. I do not believe in superstition. I only believe in karma.

Tipitaka: The pali canon (Readings in Theravada Buddhism). A vast body of literature in English translation the texts add up to several thousand printed pages. Most -- but not all -- of the Canon has already been published in English over the years. Although only a small fraction of these texts are available here at Access to Insight, this collection can nonetheless be a very good place to start.
