A remarkable discovery occurred on Thursday, July 10, 2025, when a female Loggerhead Turtle (Caretta caretta) was found in the waters of the Thousand Islands National Park by a university student conducting a field internship program. The turtle, estimated to be between 30 to 40 years old, represents one of the rarer marine turtle species found in Indonesian waters, especially around the Thousand Islands area.
When discovered, the turtle exhibited an impressive carapace (shell) size measuring approximately 100 cm in length and 80 cm in width. Larger individuals of this species are known to reach up to 280 cm in length and weigh as much as 450 kg. Loggerhead turtles grow slowly, taking between 15 to 30 years to reach maturity and reproductive age. However, the condition of this particular turtle was less than ideal, as numerous barnacles were attached to its carapace, indicating it may have been in poor health or stranded for some time. Following its discovery, the turtle was evacuated to a local conservation center for further observation and medical assessment.
This finding serves as a significant biodiversity record for the area, given that Loggerhead Turtles are much less commonly encountered in Indonesia compared to Green Turtles (Chelonia mydas) or Hawksbill Turtles (Eretmochelys imbricata). The event also highlights the ecological importance of the Thousand Islands National Park as a vital habitat and refuge for protected marine species. Such discoveries emphasize the ongoing need for marine conservation and continued monitoring efforts in Indonesian coastal ecosystems.
The Loggerhead Turtle, scientifically known as Caretta caretta, is a widely distributed species inhabiting the Pacific, Atlantic, and Indian Oceans. It is listed as “Vulnerable” on the IUCN Red List, reflecting the global concern for its declining population due to habitat degradation, pollution, and incidental capture in fishing activities. One of the most distinctive characteristics of this species is its large head and powerful jaws, which enable it to feed on hard-shelled prey such as crabs, mollusks, and shellfish. These turtles are also highly migratory navigators, capable of traveling thousands of kilometers and returning precisely to their natal beaches to nest — a remarkable natural instinct that continues to intrigue marine biologists.
This discovery by the student not only contributes valuable data for marine biodiversity monitoring but also reinforces the importance of student participation in conservation research and practical field training. By engaging in such activities, students play an active role in supporting Indonesia’s broader efforts to protect endangered marine wildlife and maintain the balance of coastal ecosystems. The observation of this Loggerhead Turtle further underscores the ecological significance of the Thousand Islands National Park as a sanctuary for vulnerable marine species and as a living laboratory for environmental research and education.
