Olive Ridley Sea Turtle is the smallest and most abundant among all sea turtles found in the tropical world. They are found mostly in warm and tropical water, primarily in the Pacific and the Indian Ocean.
Growing to about 2 feet in length and weighing around 35 kilos, Olive Ridley Turtle is best known for their behaviour of synchronized nesting in mass number, termed arribadas. Females return to the same beach from where they hatched to lay their eggs. They lay their eggs in conical nests about one and a half feet deep, which they laboriously dig with their hind flippers. Gahiramatha and Rusikulya Estuaries are the world’s largest mass nesting sites for olive turtles.
Mating often occurs in the vicinity of nesting beaches, but copulating pairs have been reported over 1000 km from the nesting beaches.
Olive Ridley Sea Turtles migrate in large numbers from the beginning of November every year for mating and nesting on the coast of Odisha. Within two months the nesting season starts.
However, though listed as vulnerable under IUCN and protected under the ‘Migratory Species Conservation’ there is a high rate of their mortality due to collision with boats, trawlers, gillnets ghost nets and longline fishing. In addition, coastal development, natural disasters, climate change and beach erosion have also become potential threats to nesting grounds.

There is also a lack of public awareness about Olive Ridley Turtles in Odisha. Both as ideas of beautification and generating awareness recently part of Bhubaneswar’s public walls were illustrated with cycles of their migration and nesting on Odisha coast.
The drive for beautification started in October 2018 with an eye on Odisha Hockey World Cup that was held in Bhubaneswar in the following months. The artwork was carried out by 15 groups of artists from Odisha Modern Art Gallery, Krutika, Konark Arts, Bakul Foundation and Sutra Advertising apart from several individual artists. Each of the groups had submitted proposals on themes focusing on wildlife, folk and urban lifestyles, hockey and tangible and intangible heritage of Odisha in general and Bhubaneswar in particular.
Bhubaneswar’s AG Square where murals are drawn is located at the heart of the city, at a distance of 2 km from the Airport and the Railway Station. Go in the early morning to avoid traffic. For Olive Ridley Turtle sighting the best place is however Ruikulya Estuary, 150 km from Bhubaneswar towards south on Berhampur Highway. February and March are the nesting seasons.
The AG Square area, which forms the city’s most prime location, was chosen for Olive Ridley Turtle and the work was assigned to artist Satyabrata.
Olive Ridley Turtle (Oly) was also the official mascot for Odisha Hockey World Cup 2018. One section of the walls focused on Oly as hockey players.
Today any passerby on the roads around AG Square is drawn for a moment to these beautiful murals and for children no doubt these together have become an open-air picture book to explore the world of Olive Ridley Turtle.
