Travelling to the heart of the Indian Ocean in the footsteps of sea turtles

Sea turtles, these ancient creatures, with a history spanning over 100 million years, fulfill several crucial functions essential for the well-being of our oceans.

TOURISMER highlights the vital role of sea turtles in marine ecosystems, which is both essential and intriguing.

These creatures are instrumental in maintaining the balance of marine environments. For example, green turtles primarily graze on seagrass, which requires regular trimming to thrive. By consuming seagrass, they help regulate its growth, thereby promoting the health of underwater meadows that serve as critical breeding and developmental habitats for various marine species.

Furthermore, sea turtles contribute to nutrient cycling. Their nesting activities on beaches, including the laying of eggs and the presence of unhatched eggs, enrich coastal ecosystems with essential nutrients that support a diverse array of plant and animal life. This process is crucial for the health and resilience of coastal areas. In addition, sea turtles play a role in controlling jellyfish populations. Leatherback turtles, in particular, feed primarily on jellyfish, thereby mitigating jellyfish blooms that could adversely affect other marine creatures and human activities.

Sea turtles Species in the Indian Ocean

Six species of sea turtles can be found in the Indian Ocean:

Green Sea Turtle (Chelonia mydas)

Green turtles are one of the largest sea turtle species, named for the green hue of their fat and characterized by a smooth, heart-shaped shell. They inhabit tropical and subtropical waters, feeding on seagrass and visiting coral reefs.

Key nesting sites include the Seychelles, Comoros, Madagascar, and the eastern coast of Africa.

Hawksbill Sea Turtle (Eretmochelys imbricata)

Hawksbill turtles are distinguished by their pointed beaks and the intricate, overlapping scales on their shells, historically sought after for tortoiseshell products. They prefer coral reef environments where they feed on sponges, anemones, and various invertebrates. Hawksbills also inhabit mangrove swamps and coastal lagoons.

Prominent nesting areas encompass the Seychelles, the Maldives, and the coastal regions of India and Sri Lanka.

Loggerhead Sea Turtle (Caretta caretta)

Loggerheads are characterized by their robust heads and powerful jaws. Their reddish-brown shells distinguish them, with a slightly smaller size compared to green turtles. Loggerhead turtles occupy diverse habitats, including open ocean, coastal waters, and bays. Their diet consists mainly of mollusks, crustaceans, and jellyfish.

Key nesting locations encompass Oman, which hosts a significant nesting population globally, and various regions along the Arabian Peninsula.

Leatherback Sea Turtle (Dermochelys coriacea)

The leatherback sea turtle is the largest and most migratory among sea turtle species. They are identifiable by their lack of a hard shell, replaced by a leathery, oil-saturated skin. Leatherbacks are distributed across tropical and temperate waters, undertaking long-distance journeys through the open ocean. Their diet predominantly comprises jellyfish.

Important nesting sites include the Andaman and Nicobar Islands, Indonesia, and segments of the eastern African coast.

Olive Ridley Sea Turtle (Lepidochelys olivacea)

Olive Ridleys, the smallest sea turtle species, sport an olive-colored shell. They are notable for their mass nesting events known as arribadas. Typically found in open ocean waters and coastal bays, Olive Ridleys feed on crustaceans, fish, and algae.

Major nesting sites include Odisha in India, Sri Lanka, and several islands in the Indian Ocean.

Flatback Sea Turtle (Natator depressus)

The flatback sea turtle features a flat, smooth shell and is endemic to Australian waters, exhibiting a pale grey to olive-colored shell. Flatbacks are primarily located in shallow coastal waters, favoring soft-bottom habitats like bays and estuaries. Their diet comprises various invertebrates and sea cucumbers.

While predominantly nesting on the northern coast of Australia, flatbacks are occasionally found in the waters of the eastern Indian Ocean.

Migration routes of sea turtles in the indian ocean

Marine turtles in the Indian Ocean travel great distances between their nesting sites and feeding areas. Turtles have an incredible sense of direction that allows them to return precisely to their birthplaces.

Green sea turtles migrate long distances for feeding, often visiting coral reefs and seagrass beds. For instance, Seychelles turtles may travel to the African coast or Madagascar, while those from the Cocos Islands head to Southeast Asia. Juvenile turtles inhabit various environments and shift from a carnivorous to an herbivorous diet as they mature, grazing on seagrass, which supports marine ecosystem health. Hatchlings face numerous dangers after emerging from nests, with few surviving to adulthood, highlighting the importance of preserving nesting and feeding areas. Conservation efforts are crucial in protecting green turtles by reducing bycatch, safeguarding nesting sites, and combating illegal trade, fostering hope for their future in the wild.

Hawksbill sea turtles often linked to coral reefs for its food (sponges), follows migratory routes in the western Indian Ocean. Hawksbill turtles from the Seychelles or Maldives often migrate to warmer waters, such as those of Madagascar or Mozambique.

Loggerhead sea turtles in the Indian Ocean travel vast distances, such as nesting in Oman and feeding along southern Africa or India. Their journeys highlight their navigational skills and ecological importance, as they support seagrass beds and coral reefs, benefiting marine life. However, they face threats like habitat destruction, accidental capture, pollution, and climate change.

Leatherback sea turtles, known to be the most migratory of sea turtles, crosse large portions of the Indian Ocean. They often migrate from the beach nesting areas of Indonesia, India or East Africa to more temperate waters to the south, in search of jellyfish, their main food source. These incredible journeys can span thousands of miles, showcasing the remarkable endurance and navigational prowess of these ancient mariners. Leatherback turtles are easily distinguishable by their lack of a hard shell; instead, they possess a leathery, flexible carapace that allows them to dive to great depths—sometimes over 1,000 meters—in pursuit of prey.

Olive ridley sea turtles in the Indian Ocean, while less migratory than other species, travel between nesting and feeding sites along the coasts of India, Sri Lanka, and the Maldives. They are vital for marine ecosystems, maintaining seagrass beds and coral reefs that support diverse marine life. During nesting season, females return to their birth beaches, guided by Earth’s magnetic fields, to lay over a hundred eggs in the sand. The hatchlings then face a dangerous journey to the ocean, with only a few surviving to adulthood, showcasing the species’ resilience.

Flatback sea turtles are primarily located in the waters surrounding Australia and Papua New Guinea, exhibiting limited migration patterns within the Indo-Pacific region. Nesting sites are predominantly found along the northern coast of Australia, including regions such as Western Australia, the Northern Territory, and Queensland, particularly at locations like Crab Island, Barrow Island, and the southern Great Barrier Reef. Following nesting, these turtles tend to forage in the adjacent shallow waters, primarily consuming sea cucumbers, jellyfish, and other soft-bodied organisms. They predominantly inhabit Australia’s coastal waters, steering clear of the deeper Indian Ocean. Their migrations, while spanning hundreds of kilometers, are largely confined to the northern continental shelf, notably within the Timor and Arafura Seas.

The dangers and protective measures

Dangers Facing Sea Turtles in the Indian Ocean include habitat destruction, pollution, and bycatch. Coastal development and human activities often lead to the degradation of nesting beaches, making it difficult for female turtles to lay their eggs. Additionally, light pollution can disorient hatchlings, leading them away from the safety of the ocean.

Pollution, particularly plastic waste, poses another significant threat. Sea turtles frequently mistake plastic bags for jellyfish, a favorite food source, which can lead to ingestion and often fatal blockages. Chemical pollutants can also affect their health and reproductive success.

Bycatch, the accidental capture of sea turtles in fishing gear, is another major issue. Turtles can become entangled in nets and fishing lines, leading to injuries or drowning. Efforts are being made to develop turtle-friendly fishing gear and implement stricter regulations, but the problem persists.

Climate change further exacerbates these dangers. Rising sea levels and increased storm frequency can erode nesting beaches, while higher sand temperatures can skew the sex ratio of hatchlings, as temperature determines the sex of the offspring.

Protective Measures to Conserve Sea Turtles in the Indian Ocean are crucial for maintaining the biodiversity and ecological balance of the region. One of the primary steps involves the establishment of marine protected areas (MPAs) where fishing and other disruptive activities are regulated or prohibited, providing a safe haven for sea turtles to feed, mate, and nest.

Additionally, community-based conservation programs can play a significant role. Engaging local communities in conservation efforts not only raises awareness but also fosters a sense of stewardship. These programs can include beach clean-ups, monitoring of nesting sites, and education on sustainable fishing practices.

Another effective measure is the implementation of turtle-friendly fishing gear, such as the use of turtle excluder devices (TEDs) in trawl nets. These devices allow sea turtles to escape while retaining the targeted fish species, significantly reducing bycatch and mortality rates.

Furthermore, international cooperation is essential. Many sea turtle species are migratory, traveling vast distances across the ocean. Collaborative efforts among countries bordering the Indian Ocean can ensure that conservation measures are standardized and enforced across national boundaries.

Public awareness campaigns and educational initiatives are equally important. By informing people about the plight of sea turtles and the importance of their conservation, we can garner broader support for protective measures. Schools, media outlets, and social platforms can be instrumental in spreading this message.

Finally, ongoing research and monitoring are vital. By studying sea turtle behavior, migration patterns, and population dynamics, scientists can make informed decisions and adapt conservation strategies as needed. This scientific approach ensures that conservation efforts are both effective and sustainable.

In summary, a combination of protected areas, community involvement, turtle-friendly fishing practices, international cooperation, public education, and scientific research forms a comprehensive strategy to conserve sea turtles in the Indian Ocean. By working together, we can help ensure that these magnificent creatures continue to thrive for generations to come.
