Concept notes: The Olive Ridley Turtle is a species of sea turtle known for its small size and abundance. It is one of the most common species of sea turtles and is particularly notable for its mass nesting events, known as arribadas, which occur on the coast of Odisha, India. This species is crucial for marine biodiversity and is a significant focus of conservation efforts.
Explanation: The Olive Ridley Turtle (Lepidochelys olivacea) is a species of sea turtle that is widely recognized for its small size and abundance. It is one of the smallest sea turtles, with adults typically measuring between 60 to 70 cm in length and weighing around 45 kg. The Olive Ridley Turtle is named for its olive-green colored carapace, which is heart-shaped and relatively thin compared to other sea turtle species.
This species is known for its unique nesting behavior, particularly the mass nesting events called arribadas. During these events, thousands of female Olive Ridley Turtles come ashore to lay their eggs simultaneously. The coast of Odisha, located in eastern India, is one of the most significant nesting sites for this species, hosting one of the largest arribadas in the world. The Gahirmatha Beach in Odisha is particularly famous for these mass nesting events, attracting thousands of turtles each year.
The Olive Ridley Turtle is classified as vulnerable by the International Union for Conservation of Nature (IUCN) due to various threats, including habitat destruction, pollution, and accidental capture in fishing gear. Conservation efforts in Odisha and other parts of the world are crucial to protect this species and ensure the continuation of its unique nesting behavior.
Understanding the Olive Ridley Turtle and its nesting habits is important for students of Odisha General Knowledge (GK) as it highlights the region's significant role in marine biodiversity and conservation. The species is a key indicator of the health of marine ecosystems and the effectiveness of conservation measures in the region. Therefore, the correct answer to the question is the Olive Ridley Turtle, as it is the smallest and most abundant sea turtle species with the coast of Odisha as one of its largest mass nesting sites in the world.
